Crustal thickness, heat flow, arc magmatism, and tectonics of Mexico-preliminary report
Contenido principal del artículo
Resumen
Se presentan mapas preliminares de espesor cortical y de flujo térmico y una discusión breve sobre la estructura cortical, tect6nica y provincias magmáticas en México. Las isopacas siguen aproximadamente la línea de la costa en el margen Pacifico y en el Golfo de México. La corteza es más gruesa (>- 40 km) en la porción central-sur del Altiplano y en la porción central-este de la Faja Volcánica Trans-Mexicana.El flujo térmico es generalmente mayor que 1.5 UFT, excepto sobre los terrenos precámbricos-Paleozoicos del sur de México y en la porción norte de Ia planicie costera del Golfo de México (-1.0 UFT). Se observan valores altos de flujo térmico en la Sierra Madre Occidental y en la Faja Volcánica Trans-Mexicana, las cuales representan provincias magmáticas del Mesozoico-Cenozoico Temprano y del Cenozoico, respectivamente.
