LEGENDOVERLAP ASSEMBLAGES PALEOCENE
Ruby Range (ca. 64-54 Ma)medium to coarse-grained equigranular, light grey to white biotite +/- horneblende granodiorite to quartz-diorite; locally contains garnet; generally massive and weakly to moderately foliated near contacts
LATE CRETACEOUSmedium-coarse grained quartz, biotite, plagioclase, horneblende granodiorite to quartz-diorite; almost protogneissic locally with some banding that appears more felsic or mafic
compositionally layered medium to coarse-grained locally mylonitic brownish biotite, quartz, plagioclase, horneblende +/- garnet diorite gneiss interlayered with creamy white quartz plag tonalite with trace biotite throughout; locally grades into coarse grained garnet amphibolite
EARLY-LATE CRETACEOUS Blanchard River Assemblage (120 Ma and younger)
fine-grained dark grey to rusty weathered quartz, biotite schist with primary bedding features preserved; locally abundant in garnet, staurolite and aluminosilicates (kyanite, sillimanite and locally andalusite); locally more fissile or blocky depending on proportions of garnet and biotite; foliation is parallel to bedding; throughout unit there is an ~5-7 cm layer of quartz, horneblende, plagioclase tonalite (?) of unknown affinity
YUKON TANANA TERRANE PROTEROZOIC TO DEVONIAN
Snowcap Assemblagefine to medium-grained well foliated amphibolite schist with garnet porphyroblasts <1 mm to 3 mm diameter; generally green/black with rusty-brown weathering surfaces; locally dark green to black massive metabasalt
fine to medium-grained quartz, muscovite, garnet psammitic schist; locally abundant kyanite porphyroblasts
fine to medium-grained quartz, muscovite, garnet schist with locally abundant kyanite and sillimanite porphyroblasts; grey to rusty weathering appearance

LEGENDOVERLAP ASSEMBLAGES PALEOCENE
Ruby Range (ca. 64-54 Ma)medium to coarse-grained equigranular, light grey to white biotite +/- horneblende granodiorite to quartz-diorite; locally contains garnet; generally massive and weakly to moderately foliated near contacts
LATE CRETACEOUScompositionally layered medium to coarse-grained locally mylonitic brownish biotite, quartz, plagioclase, horneblende +/- garnet diorite gneiss interlayered with creamy white quartz plag tonalite with trace biotite throughout; locally grades into coarse grained garnet amphibolite
EARLY-LATE CRETACEOUS Blanchard River Assemblage (120 Ma and younger)
fine-grained dark grey to rusty weathered quartz, biotite schist with primary bedding features preserved; locally abundant in garnet, staurolite and aluminosilicates (kyanite, sillimanite and locally andalusite); locally more fissile or blocky depending on proportions of garnet and biotite; foliation is parallel to bedding; throughout unit there is an ~5-7 cm layer of quartz, horneblende, plagioclase tonalite (?) of unknown affinity
YUKON TANANA TERRANE PROTEROZOIC TO DEVONIAN
Snowcap Assemblagebrown-rusty weathered and highly deformed; dark grey metavolcanic sandstone and rusty weathered conglomerate with rounded clasts up to 4 cm; dark grey-green garnet-biotite metabasalt; interlayered with marble of the Snowcap assemblage ({5Sc)

LATE CRETACEOUSmedium-coarse grained quartz, biotite, plagioclase, horneblende granodiorite to quartz-diorite; almost protogneissic locally with some banding that appears more felsic or mafic
compositionally layered medium to coarse-grained locally mylonitic brownish biotite, quartz, plagioclase, horneblende +/- garnet diorite gneiss interlayered with creamy white quartz plag tonalite with trace biotite throughout; locally grades into coarse grained garnet amphibolite
coarse-grained, dark brown-black horneblende +/- biotite, plagioclase, pyroxene, gabbro
fine to coarse-grained hornblende diorite to tonalite with abundant garnets
EARLY-LATE CRETACEOUS Blanchard River Assemblage (120 Ma and younger)
fine-grained dark grey to rusty weathered quartz, biotite schist with primary bedding features preserved; locally abundant in garnet, staurolite and aluminosilicates (kyanite, sillimanite and locally andalusite); locally more fissile or blocky depending on proportions of garnet and biotite; foliation is parallel to bedding; ~5-7 cm layers of quartz, horneblende, plagioclase tonalite (?) of unknown affinity appear
