Abstract

The geology, tectonics and seismicity of the Venezuelan Andes are Briefly reviewed. The possible origin and distribution of rocks of major geologic time intervals are discussed. Most of the rocks described are marine sediments, which have been metamorphosed and ocasionally intruded or extruded by granitic and basaltic rocks during periods of orogeny. During the Quaternary the region was affected by glaciation in its higher parts, while in the lower parts uplift- and climatic changes discccted alluvial sed.ir:nents to form. spectacular terraces.
