The geology of Cuba differs significantly from that of other Caribbean islands because of ancient 900 million year old Precambrian Proterozoic metamorphic rocks in the Santa Clara province and extensive Jurassic and Cretaceous outcrops.
Western and central Cuba are a deformed orogen, that came about due to the collision of an island arc in the Cretaceous with the Florida-Bahamas platform. As a result, the Cuban ophiolite zone became obducted and a northward verging fold and thrust belt formed. A second small orogeny took place in the Paleocene and Eocene. Eastern Cuba, southeast of the Cauto Basin, by contrast has a Cenozoic volcanic arc complex, with ophiolites north and east of the Sierra Maestra as Mesozoic-age orogen rocks overlain by Paleogene sedimentary rocks and tuff. Sedimentation due to the tectonic activity continued into the Oligocene.[1][2][3][4]
Structural Geology
- Pinar Del Rio Block:
- Esperanze zone: Thin belt of Jurassic and Cretaceous limestone, dolomite and evaporite in the west found in Cayo Coco and Los Remedios zones. Deformed by thrust faulting into three nappes.
- Sierra del Rosario zone: Antiformal arrangement of three nappes with Jurassic-Cretaceous ophiolites, siliceous slates, mafic and intermediate lava. The Quinones subzone in the component Bahia Honda subzone includes Maastrichtian limestone in thrust sheets. The Cinco Pesos subzone is the south-dipping limb of the Roasario antiform.
