... marine glauconitic sandstone unit ( Barcat et al., 1984 ), similar to that in the overlying Paleocene Salamanca sequence, is present in wells of the central basin area. No attempt was made to map the Tertiary cover because of the lack of an adequate database. Several unconformity-bound Tertiary...

... with the more ancient schists. It is believed that the eruptive cycle of Permo-Triassic was related to the formation of deposits of tungsten (Josefina mine), of chalcopyrite (Salamanca and La Barrera mines). During the Jurassic and Cretaceous the region maintained its elevation, and was subjected...
