The Eocene to Quaternary volcanic rocks associated to these structures range in composition either from subalkaline basalts to basanites or from basaltic andesite to rhyolites, and were emplaced during five magmatic events. New trace element analyses obtained by the ICP-QMS method show that the three oldest ones, ranging in age from middle Eocene to late Oligocene, emplaced potassic calc-alkaline intermediate to evolved lavas. These originated from subduction-related mafic magmas through open-system fractional cristallization coupled with assimilation and possibly melting of the continental crust. The two youngest volcanic phases (Miocene and Quaternary) emplaced intraplate subalkaline to alkaline basalt and basanites derived from variable melting degrees of enriched mantle. 2012 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56823341007 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.3 Vol.51 |
