Geomorphotectonic approach to geology of the Viñales National Park, Cuba

Abstract

The geological substratum of Viñales National Park is crossed by fractures and over-thrusts. It includes siliciclastic (Jurassic San Cayetano Formation), carbonate (Late Jurassic to Early Eocene Jagua, Guasasa, Pons and Ancón Formations) and olistostrome (Early-Middle Eocene Manacas Formation) rocks, covered by Quaternary deposits. Cartographic methodology includes Fundamental maps (geologic formations, Quaternary, tectonics and geomorphology) and Auxiliary maps (substratum-structures-drainage, slopes and lithology). Auxiliary maps provide basic information, whereas fundamental maps contribute, by means of superposition and selection, to elaborating the final geomorph-tectonic map as an essential part of the geological map. Results and conclusions are derived from the various cartographies.
