The Metallogenic Map and Provinces of the Republic of Mexico (Salas. 1976, 1980) was the end result of prolonged work to which many contributed: Genaro Gonzalez Reyna. Ruben Pesquera Velasquez, German Arriaga Garcia, Moises Martinez Manrique, Hugo Cortes Guzman, and many other members of the Mineral Resources Council (Consejo de Recursos Minerales) and of the Geological Institute (Institute Geologico, UNAM). The publication stressed the importance in metallogenesis of the geochronological epochs during which the mineral deposits originated and their correlation with petrograph ic. metallogenic. And orogenic provinces.
There is no specific definition of a metallogenic province. Many authors share basic concepts; more recently. others. Using more adva nced and sophisticated techniques. have found geo- chemical or metalliferous consanguinity in certain deposits located within certain petrographic provinces.
