Geology of Honduras (original) (raw)

The geology of Honduras includes Paleozoic metamorphic rocks, such as the Cacaguapa Schist as its basement rocks. Together with Nicaragua and El Salvador it is underlain by the Chortis Block continental fragment. Currently, the Valle de Catacamas basin extends along the Guayape fault for 290 kilometers. Early tectonic research in 1977 suggested a possible origin for the underlying land in the Pacific Ocean rather than on the Caribbean Plate. An extensive mapping project with keys in English was conducted by the University of Texas-Austin in the early 1970s.
