This province does not fit the established concept of a metallogenic province. However, its geology and physiography seem to control certain metallogenic aspects related to tectonics and epigenetic hydrothermalism over an estimated 185,000 km2 (Salas, 1975, p. 107), an area that almost crosses the country from east to west: from the Los Tuxtlas volcanic complex in Veracruz on the Gulf of Mexico to the Bahia de Banderas on the Pacific Coast of the state of Jalisco (Fig. 1).
Figures & Tables
This volume was developed, produced, and privately printed in Mexico, in Spanish, by the late Ing. G.P. Salas in 1988, as a Mexican contribution to the Geology of North America, with the understanding that it would be translated into English for inclusion in the set. The translation is by Dr. Cecily Petzall of Caracas, Venezuela, with considerable figure translation and redrafting provided by GSA. Salas worked on the volume until his death, with much valuable help from Ing. Hugo Cortez Guzmán. The result is a valuable English-language synthesis of the information available to Salas in the early to mid-1980s about the geothermal, coal, and metal-mining sectors (and some non-metallic resources) of the economic geology of Mexico.
