GUYANA SHIELD

Paleoproterozoic and

Neoproterozoic high-grade

metamorphic and felsic

intrusive rocks, part of the

Amazonian Craton

FORELAND BASIN

Mesozoic and Cenozoic

sedimentary rocks,

tectonic response to uplift

of the Andes and rifting of

the Amazon basin, with

the Amazonian craton as

basement

EASTERN CORDILLERA

Mesozoic and Cenozoic

sedimentary rocks as part

of a thrust-and-fold

deformation belt, with a

metamorphic-igneous

Paleozoic and Mesozoic

basement, inverted basin.

CENTRAL CORDILLERA

Active volcanic arc from

subduction of the Nazca Plate

under the South American Plate,

low to medium grade

metamorphic rocks act as host

rock for Mesozoic and Cenozoic

intrusions

WESTERN CORDILLERA

Cretaceous oceanic crust

accreted to the South American

Plate, which serves as basement

for Cenozoic intrusions and

volcanism

BAUDÓ-PANAMÁ ARC

Cenozoic volcanic arc and

associated rocks, accreted to

South America, possibly as part of

the accretion of the Panamá

STRATEGIC MINING AREAS

GEOSCIENTIFIC KNOWLEDGE ON STRATEGIC MINING AREAS

AREAS SELECTION

WHY AREAS SELECTION

To get geophysical, geochemical and geological information

needed to offer the first areas according to the following

requirements:

Best information

Areas without any difficulty to detailed exploration and

to develop future mining projects
