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
Isthm
