Abstract

The geology of Sinaola state consists of Precambrian metamorphic rocks(Sonobari Complex), two Paleozoic units(lower non-differentiated metamorphic rocks and upper Carboniferous sedimentary rocks), five Mesozoic units(metavolcanic, clastic, and calcareous rocks), Cenozoic volcanic rocks, and Quaternary clastic sediments and volcanic flows. The Sinaola state is potentially rich in metallic mineral resources with lower degree of non-metallic mineral resources. They are related to a variety of geological environments and are mainly physiographically located on the Sierra Madre Occidental. Mainly known mineral deposits are of gold and silver followed by zinc, lead, copper and some iron. The state also has deposits of molybdenum, tungsten and bismuth that have been occasionally exploited. There is a reference of nickel and cobalt mineralization, but these deposits have been exploited only at a small scale.
