The San Cayetano Formation is an assemblage of terrigenous sedimentary rocks, predominantly quartzo-feldspathic sandstones, siltstones, and argillites estimated to be approximately 3,000 m in thickness. The estimated thickness may be suspect since the entire formation is characterized by numerous overthrust slices. Of limited but widespread distribution within the sandstone-argillic are beds of chert, limestone, and dolomite, as well as thick black shale units which host the Zn-Pb deposits. The presence of ripple marks and crossbedding in the arenite suggests an estuarine, possibly deltaic, environment. That interpretation may be supported by the presence of the dolomite and chert layers interbedded with the siltstones and argillites. The black shales, on the other hand, are characteristic of local deeper sub-basins. The tectonics of Cuba and concluded that the terrigenous rocks, which include the San Cayetano Formation and the overlying Esperanza Formation, were deposited in a marginal basin floored by thin granite crust that passed northward into the Bahaman platform. The Cretaceous-Paleogene collisional event referred to above was also responsible for thrusting the Esperanza Formation over the San Cayetano Formation and the latter over the Paleogene sedimentary unit.
