Investigating the complex interplay between tectonics and sedimentation is a key endeavor in modern earth science. Many of the world’s leading researchers in this fi eld have been brought together in this volume to provide concise overviews of the current state of the subject.
The plate tectonic revolution of the 1960’s provided the framework for detailed models on the structure of orogens and basins, summarized in a 1995 textbook edited by Busby and Ingersoll. Tectonics of Sedimentary Basins: Recent Advances focuses on key topics or areas where the greatest strides forward have been made, while also providingon-line access to the comprehensive 1995 book.
Breakthroughs in new techniques are described in Section 1, including detrital zircon geochronology, cosmogenic nuclide dating, magnetostratigraphy, 3-D seismic, and basin modelling. Section 2 presents the new models for rift, post-rift, transtensional and strike slip basin settings. Section 3 addresses the latest ideas in convergent margin tectonics, including the sedimentary record of subduction initiation, fl at-slab subduction, and arc-continent collision; it then moves inboard to fore-arc basins and intra-arc basins, and ends with a series of papers on basins formed under compressional strain regimes, as well as post-orogenic intramontane basins. Section 4 examines the originof plate interior basins, and the sedimentary record of supercontinent formation. This book is required reading for any advanced student or professional interested in sedimentology, plate tectonics,or petroleum geoscience.
Cathy Busby got her BS from Berkeley and her PhD from Princeton University, both in Geological Sciences.She mainly works on upper crustal rocks, combining stratigraphy, structural geology, geochronology, geochemistry and paleomagnetics to solve tectonic problems. Her papers also include process-oriented studies in submarine and subaerial volcanism, clastic depositional systems, and economic geology. Her research support has come from geothermal and gold exploration industries, as well as the petroleum industry, the U.S. Geological Survey, and the National Science Foundation.

Preface
The plate tectonic revolution of the 1960’s pro-vided the first unified framework formodels on theorigin of mountain belts and basins; this resultedin an outpouring of landmark papers in the 1970’sand 1980’s. When Ray Ingersoll and Cathy Busbytaught Tectonics of Sedimentary Basins in the late1980s (at UCLA andUCSB respectively), theywerefrustrated by a lack of textbooks or summarypapers on this topic. Instead, professors wereforced to compile impossibly long reading listsfor their students, and try to synthesize the mate-rial for them. For this reason, Professors Busby andIngersoll decided to edit a textbook on the topic forBlackwell, to be aimed at the senior undergraduateto professional geologist level. This was anexhaustive treatment that took five years to pro-duce, and it was published in 1995 (Busby andIngersoll, 1995). Online access to the 1995 book isprovided by the publisher, because it still providesa valid and complete introduction to the topic. Werecommend that the undergraduate geology stu-dent begin with the 1995 book, and that the grad-uate student and professional refer to it as neededwhile reading the new book.
Fifteen years later, there have been manyadvances in our understanding of the plate tec-tonic controls on basin formation and evolution.One large area of growth has been in the field ofactive tectonics, where advances in global posi-tioning and stratigraphic or surface dating tech-niques allow workers to compare present-dayplate motions with the growth of structures onthe time scale of thousands of years. Our under-standing of the sedimentary response to tectonicevents has been improved through numerical/analog modeling and detailed field observa-tions. Major advances have been made in stud-ies of the subsurface, through seismic surveysof crustal to upper mantle structure, as well as3D seismic surveys of basin fills, in some areasaugmented by cores. Isotopic studies of detritalminerals (e.g., U-Pb zircon) are now widely usedto reconstruct tectonic events, including large-scale basin translation, patterns of unroofing inregions around basins, and reconstruction of
sediment pathways across continents throughtime. Paleomagnetic methods are now verywidely employed for precise dating and correla-tion of strata, for determining sources and flowpaths of widespread volcanic units, and for eval-uating the importance of tectonic rotation.Another new approach to understanding tectonicproblems is the use of ArcGIS to manipulategeochronological, geochemical, biostratigraphic,and paleomagnetic databases, in concert withsatellite, air photograph, and geologic map data.At the same time, proliferation of detailed modelsfor complex volcanic-volcaniclastic dispersal-depositional systems has permitted detailed tec-tonic reconstruction of a wider range of basintypes, with dateable fill. Last but not least, numer-ical and analog modeling of geodynamic pro-cesses is more sophisticated than ever.
The new book presented here was producedin response to the demand for an update on thetopic, hence the title Tectonics of SedimentaryBasins: Recent Advances. Our mission was toassemble an all-star cast in the field of basintectonics, and give them a venue to present“cutting-edge” material. Unlike the 1995 book,this is not a comprehensive treatment of the entiresubject; that was useful 15 years ago, but onlineaccess to publications has reduced the need forsuch comprehensive treatment. Instead, we thinkour new book represents the state of the art inresearch on basin tectonics. This book was pro-duced very rapidly (in about two years), becauseit consist of numerous short chapters, most ofthem authored by only one or two people. Theauthors accomplished brevity by focusing onresults of global importance and key issues raisedover the last 15 years. Primary data are not gen-erally presented here, but primary data sourcesare well cited, so the reader has a guide to allof the important recent literature on each topic.We believe the resulting chapters showcasemeth-ods and results that use innovative approachesand have led to a new understanding of tectonicprocesses, being, furthermore, “transportable” toother regions. We offer a very brief summary of
xi
the main topics addressed in the book, giving therationale for their order of appearance.
PART 1: “INTRODUCTION”
The first part of the book is an overview of the topicof this book, by Ingersoll (Chapter 1). This chapteris a thorough update on his grand overviews pub-lished in the Geological Society of AmericaBulletin in 1988, and in Tectonics of SedimentaryBasins (with Busby) in 1995. This chapter pro-vides the reader with an understanding of theprocesses and nomenclature common to all suc-ceeding chapters in the book.
PART 2: “NEW TECHNIQUESAND MODELING”
Everyone involved agreed that Tectonics ofSedimentary Basins: Recent Advances needed apart on techniques, because they have proliferatedand been refined so much in the past 15 years(the 1995 book did not have a part like this). Wemade a conscious choice to limit discussions ofapplications in these chapters, thereby keepingeach chapter as short as possible while providingreferences to applied studies. This part gives thereader an overview of themost important advancesin techniques applied to tectonic analysis of sed-imentary basins. Detrital zircon geochronologictechniques (Chapter 2) and terrestrial cosmogenicnuclide techniques (Chapter 3) have come intowidespread use. Meanwhile, magnetostratigraphictechniques, seismic interpretation techniques, andbasin/stratigraphic modeling techniques, whilenot entirely new, have become far more sophis-ticated (Chapters 4–8). This part of the book ismissing a chapter on the huge and diverse field ofchemostratigraphic techniques, which have beenevolving for decades, but a treatment of that topicwould require a second book.
The third and fourth parts of this book areorganized by tectonic setting, divided into broadlydivergent and broadly convergent margins.
PART 3: “RIFT, POST-RIFT,TRANSTENSIONAL, AND STRIKE-SLIPBASIN SETTINGS”
Part 3 opens with a chapter on the classic activeorthogonal rift in East Africa (Chapter 9). Itthen moves to transtensional rift basins in a
“successful” continental rift (Gulf of California,Chapter 10), and a transtensional rift that is stillin progress (Walker Lane, Chapter 11). Transformmargins are not dealt with here; for a global cata-logue and description of strike-slip fault systems,see the 142-page opus by Paul Mann, published in2007 (Geological Society of London Special Pub-lications, vol. 290). In keeping with our theme oftectonics and sedimentation, Part 3 of our bookalso includes the so-called passive margins thatshow evidence of deformation long after sea-floorspreading began (Chapters 12 and 13).
PART 4: “CONVERGENT MARGINS”
Part 4 is broadly organized tomove from the trenchto more inboard settings, and from sea-floor sub-duction settings to collisional settings. This beginswith an examination of processes involved insubduction initiation (Chapter 14), and continueswith new results from what is probably the best-studied modern subduction complex on Earth(Chapter 15). Part 4 then proceeds through astudy of forearc deformation by flat-slab subduc-tion (Chapter 16), and the basinal record of bring-ing arcs into continental subduction zones(Chapter 17). It continues on the theme of sea-floor subduction by examining an Andean forearcbasin (Chapter 18), as well as extensional andtranstensional intra-arc basins of the Southwest-ern USA (Chapter 19). An overview of both sub-duction-related and collisional foreland basinsfollows (Chapter 20). Then we look at basinsthat lie on top of orogens, referred to as “hinterlandbasins” (a term included in the revised nomencla-ture of Chapter 1). These are described from bothsubduction and collisional settings (Andes andTibet), on the time scale from millions of years(Chapter 21) to hundreds of thousands and thou-sands of years (Chapter 22). We then move to“intramontane” basins of the Betic Cordilleraof Spain, interpreted to be extensional basinsformed in a late orogenic setting due to mantledelamination and/or slab rollback or detachment(Chapter 23). Part 4 then moves inboard in tec-tonic setting, to the foreland. Chapter 24 exam-ines patterns of flexural subsidence in thewesternCanada foreland basin, inferred to be broadlycontrolled by oceanic plate subduction, and atthe Cordilleran scale controlled by terrane accre-tion events. Chapter 25 contrasts the elementsof a typical contiguous foreland basin (Bolivia)
xii Preface
with those of a broken foreland (Argentina).These case studies are followed by studies thatdeal with general kinematic models for thrustwedge-foreland systems (Chapter 26), and modelsfor growth fault-related folds in contractionalsettings (Chapter 27). Part 4 has an unfortunateabsence of oceanic/island arc convergent marginbasin tectonic studies; that, too, is deserving of aseparate book.
PART 5: “PLATE INTERIOR BASINSAND WIDESPREAD BASIN TYPES”
The last part of the book treats sedimentary basintectonic topics that do not fit neatly into divergentor convergent plate tectonic settings. Plate inte-rior poly-phase (PIP) basins are important fortheir size and long-term structural and strati-graphic record (Chapter 28). The vast sedimen-tary record of the Grenvillian tectonomagmaticevent is described in the context of superconti-nent assembly (Chapter 29). In Chapter 30, cra-tonic basins are described as long-lived circularor elliptical crustal sags on thick, relatively stablecontinental lithosphere, and are interpreted tobe primarily formed by protracted plate-widestretching at low strain rate. Last, Chapter 31describes the distinctive stratigraphic and sedi-mentary facies characteristics that are common toendorheic (internally drained) basins in a widevariety of tectonic settings.
There were at least a few additional topics thatwere garnering increasing attention at the time thisbook was being produced. The halokinetic basin,important for commonly containing petroleum, isnow included in Ingersoll’s revised nomenclature(Chapter 1), and it deserved its own chapterhere. New techniques are rapidly evolving todeduce paleo-elevations from sedimentary basinfills, using stable isotopes in paleosols, fossils,silicates, and volcanic glasses, but these are treatedelsewhere (e.g., see Reviews in Mineralogy &Geochemistry, 2007, vol. 66). A very rapidlyexpanding, huge field of research uses global seis-mic tomography studies to infer linkages betweenmantle and surface processes. For example, howimportant is the role of “mantle/lithospheric drips”in causing surface subsidence (e.g., the Tulare LakeBasin of the San Joaquin Valley, California)? Arethey too small and too transient to be important?How does the subduction of huge oceanic plateauscontrol uplift and subsidence events on continents?
And how do surface tectonic basin processes pro-vide a record of tomographically imaged subduc-tion processes? Slab rollback is discussed in thisbook, but what are the effects of other processes,such as stalled slabs and broken slabs?
Like all geologic research, this book is a“progress report” on our understanding of thetectonics of sedimentary basins, which we thinkhas advanced greatly in recent years. We hope youfind the book useful. We give our sincere thanks tothe many reviewers who worked hard to give usvaluable feedback (listed below).
We thank the Spanish Ministry of Education forgranting Cathy Busby funds to work with AntonioAzor in the Department of Geodynamics at theUniversity of Granada in 2007–2008 and in2010. Without that support, this book would nothave been possible.

Tectonics of sedimentary basins, with revised nomenclature
RAYMOND V. INGERSOLL
Department of Earth and Space Sciences, University of California, Los Angeles, California
ABSTRACT
Actualistic plate-tectonic models are the best framework within which to understandthe tectonics of sedimentary basins. Sedimentary basins develop in divergent, intra-plate, convergent, transform,hybrid, andmiscellaneous settings.Within eachsetting areseveral variants, dependent on type(s) of underlying crust, structural position, sedimentsupply, and inheritance. Subsidence of sedimentary basins results from (1) thinning ofcrust (2) thickening of mantle lithosphere (3) sedimentary and volcanic loading (4) tec-tonic loading (5) subcrustal loading (6) asthenospheric flow, and (7) crustal densifica-tion. Basins vary greatly in size, life span, and preservation potential, with short-livedbasins formed in active tectonic settings, especially on oceanic crust, having lowpreservation potential, and long-lived basins formed in intraplate settings having thehighest preservation potential.Continental rifts may evolve into nascent ocean basins, which commonly evolve into
active ocean basins bordered by intraplate continental margins with three types ofconfigurations: shelf-slope-rise, transform, and embankment. Continental rifts that donot evolve into oceans become fossil rifts, which later become sites for development ofintracratonic basins and aulacogens. If all plate boundaries within and around an oceanbasin become inactive, a dormant ocean basin develops, underlain by oceanic crust andsurrounded by continental crust.Sites for sedimentary basins in convergent settings include trenches, trench
slopes, forearcs, intra-arcs, backarcs, and retroarcs. Complex dynamic behavior ofarc-trench systems results in diverse configurations for arc-related basins. Mostnotable is the overall stress regime of the arc-trench system, with resultingresponse along and behind the magmatic arc. Intra-arc rifting in highly extensionalarcs commonly evolves into backarc spreading to form new oceanic crust.Backarcs of neutral arcs can contain any type of preexisting crust that was trappedthere at the time of initiation of the related subduction zone. Highly compressional arcsdevelop retroarc foldthrust belts and related retroforeland basins, and may develophinterland basins; in extreme cases, broken retroforelands may develop in formercratonal areas.As nonsubductable continental or arc crust is carried toward a subduction zone,
collision generally initiates at one point and the resulting suture propagates awayfrom this point of initial impact. Remnant ocean basins form on both sides of theinitial impact point, and rapidly fill with sediment derived from the suture zone. Ascollision continues, the flux of sediment into the remnant ocean basin(s) increasesconcurrently with shrinkage of the basin until final suturing and obduction of theaccreted sediment occur. Concurrently with collision, proforeland basins form oncontinental crust of the subducting plate and collisional retroforeland basins formon the overriding plate. Impactogens, broken forelands, and hinterland basins alsomay result.In transform settings and along complex strike-slip fault systems related to convergent
settings, changing stress regimes related to irregularities in fault trends, rock types, andplate motions result in transtension, transpression, and transrotation, with associatedcomplex, diverse, and short-lived sedimentary basins.

Two previously unnamed basin types that have received increasing attentionrecently are halokinetic basins (related to salt tectonics, especially along intraplatemargins with embankment configurations) and bolide basins (resulting from extrater-restrial impacts). Sediment accumulates in successor basins following cessationof basin-controlling processes, whether in divergent, convergent, transform, orhybrid settings.The ultimate goal of classifying and reviewing all types of sedimentary basins is the
improvement of paleotectonic and paleogeographic reconstructions through the appli-cation of actualistic models for basin evolution. Interdisciplinary studies that test andrefine these models will improve our knowledge of Earth history.
Keywords: basin nomenclature; plate-tectonic settings; subsidence mechanisms;preservation potential; paleotectonic reconstruction
INTRODUCTION
It has beenmore than adecade since I reviewedandrevised my original basin classification (i.e., Inger-soll, 1988; Ingersoll and Busby, 1995), which wasbased primarily on Dickinson’s (1974b, 1976a)statement of fundamental principles that shouldguide discussion of the tectonics of sedimentarybasins. Many new insights and models have beendeveloped recently; in addition, nomenclature hasevolved in complex ways. Therefore, now is anappropriate time to consolidate, revise, and dis-cuss how to communicate about the tectonics ofsedimentary basins.
As inmypreviouspapers on this subject, I followDickinson’s (1974b, 1976a) suggestions thatnomen-clature and classification be based on the followingactualistic plate-tectonic processes and character-istics, which ultimately control the location, initi-ation, and evolution of sedimentary basins indiverse tectonic settings. Horizontal motions ofplates, thermal changes through time, stretchingand shortening of crust, isostatic adjustments,mantle dynamics, surficial processes, and evenextraterrestrial events influence sedimentarybasins. Additional study of sedimentary basins,inevitably, leads to greater complexity of modelsto explain them. Although we should search forunifying principles that lead to deeper under-standing of processes and results, the complexityof the real world dictates that enhanced knowledgeabout sedimentary basins results in more complexmodels. Thus, new types of sedimentary basins areadded to the list provided in Ingersoll andBusby (1995) because these are actual featuresthat need to be understood. Gould (1989, 98)stated, “Classifications are theories about thebasis of natural order, not dull catalogues compiled
only to avoid chaos.” I hope that my discussionserves the dual purposes of reducing nomencla-tural chaos and suggesting a framework withinwhich to understand the complex controls on theorigin and evolution of sedimentary basins.
NOMENCLATURE
First-order criteria for classifying sedimentarybasins (Dickinson, 1974b, 1976a) are (1) type ofnearest plate boundary(ies) (2) proximity of plateboundary(ies), and (3) type of substratum. Thus,the first-order classification, based on criteria (1)and (2) is divergent, intraplate, convergent,transform, hybrid, and miscellaneous settings(Table 1.1). Within each of these categories areseveral variants, dependent on type of substratum(oceanic, transitional, continental, and anomalouscrust), as well as structural position, sedimentsupply, and inheritance.
Basin classification and nomenclature arebased on characteristics of a basin at the time ofsedimentation. Thus, many stratigraphic succes-sions are multidimensional andmultigenerationalin terms of plate-tectonic controls on theirevolution. A single stratigraphic succession mayrepresent several different tectonic settings. “Theevolution of a sedimentary basin thus canbe viewed as the result of a succession of discreteplate-tectonic settings and plate interactionswhose effects blend into a continuum of devel-opment” (Dickinson, 1974b, 1).
It is important to realize that “basin,” as usedherein, refers to any stratigraphic accumulationof sedimentary or volcanic rock; the three-dimensional architecture of basins may approxi-mate saucers, wedges, sheets, and odd shapes.

Also, basinsmay formby subsidence of a substrate,development of a barrier to transport of sediment,filling of a preexisting hole, or relative movementof source and sink.
SUBSIDENCE MECHANISMSAND PRESERVATION POTENTIAL
Surfaces of deposition may subside due to thefollowing processes (Dickinson, 1974b, 1976a,1993; Ingersoll and Busby, 1995) (Table 1.2):(1) thinning of crust due to stretching, erosion,andmagmatic withdrawal (2) thickening ofmantlelithosphere during cooling (3) sedimentary andvolcanic loading (local crustal isostasy or regionallithospheric flexure) (4) tectonic loading of bothcrust and lithosphere (5) subcrustal loading of bothcrust and lithosphere (6) dynamic effects ofasthenospheric flow, and (7) crustal densification.Figure 1.1 illustrates that crustal thinning domi-natesduring early stages of extension (e.g., rifts andtranstensional basins), and mantle-lithosphericthickening dominates following the initiation ofseafloor spreading (during the rift-to-drift transi-tion along divergent margins which evolve intointraplate margins). Sedimentary loading domi-nates along continental-oceanic crustal bound-aries which are supplied by major rivers anddeltas (e.g., continental embankments and rem-nant ocean basins). Tectonic loading dominatesin settings where crustal shortening dominates(e.g., trenches and foreland basins). The otherthree types of subsidence mechanismsare generally subordinate.
The diversity of tectonic and structural settingsof sedimentary basins dictates that they varygreatly in size, life span, and preservationpotential (Fig. 1.2) (Ingersoll, 1988; Ingersoll andBusby, 1995; Woodcock, 2004). Many sediment
accumulations are destined to be destroyed rela-tively soon after deposition (e.g., most basinsresiding on oceanic crust or in rapidly upliftingorogenic settings). In contrast, basins formed dur-ing and following stretching of continental crust(e.g., continental rifts that either evolve into sea-floor spreading or fail to do so) have high preser-vation potential because they subside and areburied beneath intraplate deposits following rift-ing. On the other hand, stratigraphic sequencesalong intraplate continental margins are destinedto be partially subducted as they are pulled intotrenches, thus preserving thematmoderate to deepcrustal levels as highly deformed and metamor-phosed terranes. Such metasedimentary andmetavolcanic terranes, along with voluminoussediments deposited in remnant ocean basins,are major rock bodies involved in the constructionof continental crust, although their substrates(oceanic crust) are mostly subducted (e.g., Grahamet al., 1975; Ingersoll et al., 1995, 2003).
DIVERGENT SETTINGS
Sequential rift development and continentalseparation
The relative importance of “active” (mantle-convective-driven) versus “passive” (litho-spheric-driven) processes during initiation of con-tinental rifting is debated (e.g., Sengor andBurke, 1978; Ingersoll and Busby, 1995; Sengor,1995). Regardless of the mechanisms of initiationof rifting, continental rifts may experience two lifepaths: “successful” rifting that evolves into sea-floor spreading to form nascent ocean basins(Ingersoll and Busby, 1995; Leeder, 1995), whichthen evolve into active ocean basins with pairedintraplate margins (Fig. 1.3), or “failed” rifting,which does not evolve into nascent ocean basins,

different life paths during and after continentalrifting. Here, I highlight changes in nomenclatureand models involved in the evolution from conti-nental rifts to intraplate margins (the rift-drifttransition).

Intraplate con-tinental margins have high preservation potential inthe sense of retaining their basement, but are likely tobe highly deformed and metamorphosed beneath andwithin suture belts, and may be difficult to recognizein ancient settings.

10 Part 1: Introduction
Continental rifts
The most common basins associated with conti-nental rifts (Fig. 1.3b) (“terrestrial rift valleys” ofDickinson, 1974b; Ingersoll, 1988) are half grabensdeveloped on the hanging walls of normal faults(Leeder and Gawthorpe, 1987; Leeder, 1995;Gawthorpe and Leeder, 2000). Gawthorpe andLeeder (2000) summarized conceptual modelsfor the tectono-sedimentary evolution of continen-tal rift basins, including their three-dimensionaldevelopment. They discussed structural, geomor-phic, climatic, and lake/sea-level influences onbasin development.
All of the models presented by Gawthorpe andLeeder (2000) involve high-angle normal faults. Inthese half grabens, most sediment is derived fromthe hanging wall, whereas the coarsest material,which is derived primarily from the footwall, isrestricted to small steep alluvial fans or fan deltasalong the faulted basin boundary. In contrast,supradetachment basins (formed above low-angle normal faults) receivemost of their sedimentfrom the breakaway footwall and tend to be dom-inated by coarse-grained detritus (Friedmann andBurbank, 1995). Additional variants on theGawthorpe and Leeder (2000) half-graben modelinclude development of accommodation zones,relay ramps, anticlinal-full-grabenbasins, and syn-clinal-horst basins (Rosendahl, 1987; Faulds andVarga, 1998; Ingersoll, 2001; Mack et al., 2003).
Nascent ocean basins and continental margins
As continental lithosphere is stretched andthinned, mantle asthenosphere eventually risesclose to the surface (Fig. 1.3c). During the transi-tion from continental rifting to seafloor spreading,transitional crust forms, either as stretched conti-nental crust (quasicontinental) or sediment-richbasaltic crust (quasioceanic) (Dickinson, 1974b;Ingersoll, 2008b). Continental rifting evolves intoseafloor spreading only in the absence of signifi-cant sediment so that oceanic crust is the only solidmaterial with which rising asthenospheric meltscan interact (Einsele, 1985; Nicolas, 1985). Thus, asignificant width of transitional crust typicallyforms on the margins of nascent ocean basinsprior to initiation of true seafloor spreading.
As these transitional types of crust form andthe two continental margins move apart, anascent ocean basin develops (“proto-oceanicgulf” and “narrow ocean” of Dickinson (1974b);
“proto-oceanic rift trough” of Ingersoll (1988)).The Red Sea is the type nascent ocean basin,with active seafloor spreading, clastic andcarbonate sedimentation along the margins, anduplifted rift shoulders along the continentalmargins (Cochran, 1983; Bohannon, 1986a,1986b; Coleman, 1993; Leeder, 1995; Purser andBosence, 1998; Bosworth et al., 2005). Thick evap-orite deposits may form during the transitionfrom rift basin to nascent ocean basin, as well asduringmuchof the history of nascent oceanbasins,given the right combination of arid climate, limitedcommunication with other marine bodies, andlack of detrital input (Dickinson, 1974b). TheGulf of California is an example of a transtensionalnascent ocean basin (e.g., Atwater, 1989;Lonsdale, 1991; Atwater and Stock, 1998; Axenand Fletcher, 1998).
INTRAPLATE SETTINGS
Intraplate continental margins
Nascent ocean basins evolve into wide (Atlantic-type) oceans as two continents diverge alongspreading ridges. During this evolutionary pro-cess, the newly rifted continental margins withuplifted rift flanks cool and subside as theymove away from the spreading ridge. This processis referred to as the “rift-to-drift” transition, as adivergent setting evolves into an intraplate setting(Dickinson, 1974b, 1976a; Ingersoll, 1988; Bondet al., 1995; Ingersoll and Busby, 1995). Withjacket al. (1998) discussed complications in timing andprocess during this transition.
Subsidence mechanisms evolve from (1) thin-ning of continental crust by stretching and erosionduring doming and rifting, to (2) thermal subsi-dence following rifting as the intraplate marginmoves away from the spreading ridge, to (3) bothlocal crustal and regional lithospheric sedimentloading during the later history of the intraplatecontinentalmargin (Bondet al., 1995; Ingersoll andBusby, 1995). Lower-crustal and subcrustal flowand densification can locally modify subsidence.
Shelf-slope-rise configuration
Most mature intraplate continental margins con-sist of a seaward thickeningwedgeof shelf depositson top of continental crust, which is thinner sea-ward (Fig. 1.3d). Transitional crust (both quasicon-tinental and quasioceanic; Dickinson, 1974b,
Tectonics, with revised nomenclature 11
1976a) underlies the seaward transition from thickshelf deposits to thin slope deposits, which, inturn, merge into thick turbiditic rise and abyssal-plain deposits on oceanic crust (Bond et al., 1995;Ingersoll and Busby, 1995). Most modern Atlanticcontinental margins have this configuration, withcarbonate environments dominating at lower lati-tudes devoid of extensive clastic input.
Transform configuration
Intraplate continental margins that originate alongtransform boundaries rather than rift boundarieshave narrower sediment prisms and transitionalcrust (Fig. 1.3e). Tens ofmillions of years may passbetween the time of initiation of transform motion(coincident with the rift-to-drift transition onadjoining margins) and the time of intraplate sed-imentation (following passage of the spreadingridge along the transform boundary) (e.g., Bondet al., 1995; Turner et al., 2003;Wilson et al., 2003).The southern coast of West Africa exemplifiesthese characteristics; the latest Proterozoic -early Paleozoic Alabama-Oklahoma transformmargin is an ancient example (e.g., Thomas, 1991).
Embankment configuration
Major rivers along intraplate continental marginscommonly are localized by fossil rifts trending athigh angle to themargins (Burke and Dewey, 1973;Dickinson, 1974b; Audley-Charles et al., 1977;Ingersoll and Busby, 1995). The best examplesare the Niger Delta (Burke, 1972) and the Missis-sippi Delta (Worrall and Snelson, 1989; Salvador,1991; Galloway et al., 2000), where the shelf edgehas prograded over oceanic crust because themax-imum sediment thickness allowed by isostaticloading (16–18 km; Kinsman, 1975) has beenreached inland of the shelf edge (Fig. 1.3f).In the case of the USA Gulf Coast, several riversin addition to the Mississippi have contributed toconsiderable progradation of the continental mar-gin over a wide area; this is the type example of acontinental embankment, a distinctly differentconfiguration than either the shelf-slope-rise ortransform configuration.
Intracratonic basins
Most intracratonic basins (e.g., Michigan basin)overlie fossil rifts (e.g., DeRito et al., 1983;Quinlan, 1987; Klein, 1995; Sengor, 1995; Howell
and van der Pluijm, 1999) (Fig. 1.3a). Renewedperiods of subsidence in cratonic basins can gen-erally be correlated with changes in lithosphericstress related to orogenic activity in neighboringorogenic belts (DeRito et al., 1983; Howell and vander Pluijm, 1999). Subsidence occurs when litho-spheric rigidity lessens, allowing uncompensatedmass in the upper crust (remnants of fossil rifts) tosubside over a broad area. Between times of oro-genic activity, the lithosphere strengthens so thatattainment of local isostatic equilibrium is inter-rupted. Thus, an intracratonic basinmay take hun-dreds of millions of years to reach full isostaticcompensation (DeRito et al., 1983; Ingersoll andBusby, 1995; Howell and van der Pluijm, 1999).
Continental platforms
Cratonal stratigraphic sequences primarilyreflect global tectonic events and eustasy (e.g.,Sloss, 1988; Bally, 1989), although mantle dynam-ics, and local and regional events also influencecontinental platforms (e.g., Cloetingh, 1988;Burgess and Gurnis, 1995; van der Pluijmet al., 1997; Burgess, 2008). In contrast to intracra-tonic basins, platforms (Fig. 1.3a) accumulate sed-iment ofuniform thicknessover continental scales.Platformal stratigraphic sequences are transitionalinto continental margins, intracratonic basins,foreland basins, and other tectonic settings alongcontinental margins (Ingersoll and Busby, 1995;Burgess, 2008). The distinction of distal forelandand platform sequences may be arbitrary, espe-ciallyduring times of high sea level, high carbonateproductivity, and broad foreland flexure. Eustati-cally induced cyclothems are best expressed onplatforms (e.g., Heckel, 1984; Klein, 1992; Kleinand Kupperman, 1992), and paleolatitude andpaleoclimate signals are best isolated in platformalsequences (Berry and Wilkinson, 1994). Platformshave generally experienced exposure and erosionduring times of supercontinents, and have experi-enced maximum flooding approximately 100My after supercontinent breakup (Heller andAngevine, 1985; Cogne et al., 2006).
Active ocean basins
The systematic exponential thermal decay of oce-anic lithosphere as it moves away from spreadingridges is expressed by increasing water depthwith age of oceanic crust (Sclater et al., 1971;Parsons and Sclater, 1977; Stein and Stein, 1992)
12 Part 1: Introduction
(Fig. 1.3g). As oceanic crust subsides with age anddistance from spreading ridges, systematic pelagicand hemipelagic deposits accumulate (Berger,1973; Heezen et al., 1973; Winterer, 1973; Bergerand Winterer, 1974). Carbonate ooze accumulatesabove the carbonate compensation depth(CCD), which is depressed under areas of highbiologic productivity; silica ooze accumulatesabove the poorly defined silica compensationdepth (SCD); and only abyssal clay accumulatesbelow the SCD. The result is a dynamic and pre-dictive stratigraphy relating the age, depth, andpaleoaltitude of oceanic crust to oceanic deposi-tional facies. Volcaniclastic and turbidite depositsnear magmatic arcs and continental marginscomplicate predicted stratigraphic sequences onoceanic plates (e.g., Cook, 1975; Ingersoll andBusby, 1995).
Oceanic islands, seamounts, aseismic ridges,and plateaus
Islands, seamounts, ridges, and plateaus thermallysubside as oceanic plates migrate away fromspreading ridges. Thermal anomalies independentof spreading ridges (e.g., hot spots) create newislands, ridges, and plateaus, which may havecomplex subsidence histories, dependent ontheir magmatic histories. Clague (1981) dividedthe post-volcanic history of seamounts into threesequential stages: subaerial, shallow water, anddeep water or bathyal (Ingersoll, 1988; Ingersolland Busby, 1995). As an island is eroded andsubsides, fringing reefs and atolls may form,depending on latitude, climate, and relativesea level (e.g., Jenkyns and Wilson, 1999;Dickinson, 2004). Oceanic features, which maybecome accreted terranes at convergent margins(e.g., Wrangellia of the North American Cordillera;Ricketts, 2008), range in size from small seamountsto large mafic igneous provinces, such as theOntong Java Plateau and related features (e.g.,Taylor, 2006).
Dormant ocean basins
Dormant ocean basins are floored by oceanic crust,which is neither spreading nor subducting; inother words, there are no active plate marginswithin or adjoining the basin (Ingersoll andBusby, 1995) (Fig. 1.3h). This setting contrastswith active ocean basins, which include at leastone active spreading ridge (e.g., Atlantic, Pacific,
and Indian oceans), and remnant ocean basins,which are small shrinking oceans bounded by atleast one subduction zone (e.g., Bay of Bengal andHuonGulf). The term “dormant” implies that thereis no orogenic or taphrogenic activity within oradjacent to the basin; “oceanic” requires thatthe basin is underlain by oceanic lithosphere,in contrast to intracratonic basins, which are typ-ically underlain by partially rifted continentallithosphere (Ingersoll and Busby, 1995).
Dormant ocean basins are created by two con-trasting processes: (1) spreading ridges of nascentocean basins cease activity (e.g., Gulf of Mexico;Pindell andDewey, 1982; Pindell, 1985; Dickinsonand Lawton, 2001), or (2) backarc basins (eitherextensional or neutral) are not subducted duringsuturing of continents and/or arcs (e.g., Black Sea;Okay et al., 1994) or South Caspian basin (Brunetet al., 2003; Vincent et al., 2005). The origin ofdormant oceanbasinsmaybedifficult todeterminebecause basement and original strata commonlyremain deeply buried for hundreds of millionsof years following cessation of seafloor spreading(e.g., Tarim and Junggar basins of western China)(e.g., Sengor et al., 1996). Following cessation ofplate activity within and around the basin, sedi-ment loading is the dominant subsidence mecha-nism, although lithospheric thickening due toresidual cooling may be important (Ingersoll andBusby, 1995). Dormant ocean basins may have lifespans of hundreds of millions of years and mayvary considerably in size. The modern Gulf ofMexico, the largest known dormant ocean basin,is filling rapidly along its northern margin (thecontinental embankment of the Gulf Coast), butstill contains oceanic crust with thin sedimentcover in the south (e.g., Buffler and Thomas, 1994;Galloway et al., 2000; Dickinson and Lawton,2001). The South Caspian Basin is small and par-tially filled with sediment (locally over 20 kmthick; Brunet et al., 2003), andyet still is an oceanicbasin. In contrast, the Tarim basin has a compara-ble sediment thickness, but is completely filled.These three basins are likely underlain by oceaniccrust, or in the case of Tarim, an oceanic Plateau(Sengor et al., 1996); their long histories of coolingmeans that they are also underlain by thick andstrong mantle lithosphere (Ingersoll andBusby, 1995). When a dormant ocean basin isfilled to sea level, it may superficially resemblean intracratonic basin. The former, however, con-tains 16–20 km of sedimentary strata on topof strong oceanic lithosphere, whereas the latter
Tectonics, with revised nomenclature 13
contains a few km of sedimentary strata underlainprimarily by continental crust, with one or morefossil rifts beneath the basin center. Thus,when in-plate stresses affect dormant oceanbasins and theirsurroundings, deformation usually occurs alongtheir weak boundaries, whereas deformation ofintracratonic basins is concentrated along the fos-sil rifts underlying their interiors. Foreland basinsmay form above the edges of dormant ocean basinsduring contractional deformation (e.g., the mar-gins of the modern Tarim basin). Intracratonicbasins may experience renewed subsidence orinversion tectonics (e.g., the modern North Sea)(Cooper andWilliams, 1989; Cameron et al., 1992).
CONVERGENT SETTINGS
Arc-trench systems
Arc-trench systems may be categorized into threefundamental types: (1) extensional (2) neutral, and(3) compressional (Dickinson and Seely, 1979;Dewey, 1980) (Fig. 1.4). Arc-trench systems withsignificant strike slip may be considered a fourthtype (Dorobek, 2008); strike-slip faults may occurin all types of arc-trench system, but they areespecially common in strongly coupled systemsexperiencing oblique convergence (Beck, 1983).Many parameters determine the behavior of arc-trench systems, but the most important factorsappear to be (1) convergence rate (2) slab age,and (3) slab dip (Molnar and Atwater, 1978;Uyeda and Kanamori, 1979; Jarrard, 1986;Kanamori, 1986), based on analyses of modernarc-trench systems (although see Crucianiet al., 2005, for an alternative interpretation). Amajor question arises from these analyses of con-temporary Earth: is the present arrangement ofspreading ridges and arc-trench systems typicalof Earth history or an unusual configuration?Almost all modern east-facing arcs (e.g., Marianas)are extensional,with subductionof old lithosphereat steep angles. Almost all west-facing arcs (e.g.,Andes) are compressional, with subduction ofyoung lithosphere at shallow angles. Most south-facing arcs (e.g., Aleutians) are neutral, with sub-duction of middle-aged lithosphere at moderateangles. There are no north-facing arcs. Thus, it isvery difficult to separate the covarying parametersof slab age, slab dip, facing direction, and type ofarc-trench system. There is growing consensus(although see Schellart, 2007, 2008, for a contraryview) that facing direction of arc-trench systems
may be the fundamental determinant of thebehavior of arc-trench systems because of west-ward tidal lag of the eastward rotating planet (e.g.,Bostrom, 1971; Moore, 1973; Dickinson, 1978;Doglioni, 1994; Doglioni et al., 1999). If this isthe case today, then it should have been the casethroughout Earth history because of the constancyof eastward planetary rotation. Therefore, modelsfor ancient arc-trench systemsmust account for theazimuth of their facing directions when they wereactive. Lack of recognition of this fundamentalcharacteristic of arc-trench systems has resultedin many invalid analog models of ancient moun-tain belts (Dickinson, 2008).
Dickinson (1974a, 1974b), Ingersoll (1988),Ingersoll and Busby (1995) and Dorobek (2008)summarized tectonic settings and subsidencemechanisms of the diverse basin types related toarc-trench systems. Ingersoll and Busby (1995),and Smith and Landis (1995) also discussed con-struction and erosion of arc edifices that providemost sediment to neighboring basins.
The distinction of forearc, intra-arc, and backarcbasins is not always clear. Intra-arc basins aredefined as thick volcanic-volcaniclastic andother sedimentary accumulations along the arcplatform, which is formed of overlapping or super-posed volcanoes. The presence of vent-proximalvolcanic rocks and related intrusions is critical tothe recognition of intra-arc basins in the geologicrecord, since arc-derived volcaniclastic materialmay be spread into forearc, backarc, and otherbasins. A more general term, “arc massif,” refersto crust generated by arc magmatic processes(Dickinson, 1974a, 1974b), and arc crust mayunderlie a much broader region than the arc plat-form. The distinction of forearc and intra-arcbasins is also discussed by Dickinson (1995).Many backarc basins form by rifting within thearc platform (Marsaglia, 1995), and were intra-arc basins in their early stages. Also, forearc,intra-arc and backarc settings change temporallyand are superposed on each other due to bothgradual evolution and sudden reorganization ofarc-trench systems resulting from collisionalevents, plate reorganization, and changes inplate kinematics.
