Geology and Evolution of the Habana-Matanzas Region, Cuban Thrust Belt

G. Barcelo-Carol, J. G. Lopez-Rivera, J. Alvarez-Castro, R. Garcia-Sanchez, O. Rodriguez-Moran

The Habana-Matanzas region is a 100 kilometer sector of the Cuban Thrust Belt, extending to the East of the city of Havana. It has a complex alpine style structure developed during the upper Cretaceous and Paleogene, on the collisional boundary formed by the Zaza volcanic arc and the southern margin of continental North America.

The Zaza tectono-stratigraphic unit (TSU) rocks, composed of ophiolites and volcanics, were thrusted and imbricated over the continental margin Placetas TSU rocks, which in turn were also thrusted and imbricated over the Camajuani TSU continental margin rocks forming the foreland basin. The sedimentary cover has become detached just above the sediment-basement contact.

The geologic evolution for this interesting region and the possible formation of a triangle zone are discussed.
