Structural geomorphology of the south-western shell of Cuba with regard to the problem of oil and gas prospecting

Abstract

According to the structural-geomorphic subdivision of the SE shelf of Cuba and adjacent parts of the island itself two regions were identified: Cuban fold-block structure and Caiman geoanticlinal zone. The Cuban structure is subdivided into Central Cuban uplift zone, South Cuban trough zone and marginal uplift zone of the southern shelf, the Caiman zone is divided into Manzanillo-Guantanamo trough zone and Sierro-Maestra anticlinorium. The boundary of the regions in its western part coincides with large fault revealed by seismo-acustic profiling. 37 structures of medium and small size have been identified, regions are outlined which can be of interest for oil and gas prospecting.
