Structure of the southern Jalisco subduction zone, Mexico, as inferred from gravity and seismicity
Contenido principal del artículo
Resumen
Un modelo característico de la estructura geológica de la zona de subducción de Jalisco (JSZ) es determinado por la comparación de las anomalías gravimétricas a lo largo de un perfil perpendicular a la costa de Jalisco cerca de Barra de Navidad con la anomalía calculada de una sección geológica transversal restringida por datos de sismicidad. El espesor de la corteza continental del bloque de Jalisco es en promedio ~38 km, y aumenta gradualmente hacia el este hasta un espesor máximo de 44 km. La densidad de la parte superior de la litosfera en subducción aumenta a una profundidad de ~30 km, reflejando quizá una transición de fase de basalto a eclogita como se ha propuesto para la zona de subducción de Chile. El manto superior al oeste de la trinchera muestra densidades menores relativamente al resto del manto superior. Esta zona de baja densidad es más gruesa cerca de la Cordillera del Pacífico Este (EPR) y disminuye hacia el este en direccíon de la Trinchera Mesoamericana, y esto puede reflejar una zona extensa de magma emplazada a lo largo del EPR, similar a la observada en el EPR a los 16°S.
