The Zitacuaro Volcanic Complex, Michoacan, Mexico: magmatic and eruptive history of a resurgent caldera

The Zitacuaro Volcanic Complex (ZVC) rises on a basement of metamorphic rocks of Late Jurassic-Early Cretaceous age, and volcanic rocks, limestones, and red beds of Cretaceous age. Volcanic activity related to the Trans-Mexican Volcanic Belt started during Early Miocene with the eruption of calc-alk...

Volcanic activity related to the Trans-Mexican Volcanic Belt started during Early Miocene with the eruption of calc-alkaline andesites that formed a primitive stratovolcano covering an area about 30 km x 15 km. A major change in eruptive style occurred during Middle Miocene, when a caldera structure formed, "Las Tres Chicas Caldera", approximately 30 km in diameter and dated about 12 Ma. Post-caldera activity consisted of three eruptive episodes of intra-caldera dome resurgence around 12 Ma, 5 Ma, and 0.5 Ma. Each episode featured the intrusion of dacitic central domes, the generation of pyroclastic flows and peri-caldera andesitic lava flows. The activity at the ZVC features recurrent volcanic episodes, the most recent one with emplacement of young resurgent domes such as Cacique. Local seismic activity in the area felt at Zitacuaro, is persistent. The ZVC should be considered as a potentially active volcanic zone.El Complejo Volcánico de Zitácuaro descansa sobre un basamento mesozoico constituido por rocas metamórficas (Jurásico Tardío-Cretácico Temprano), rocas volcánicas, calizas y capas rojas del Cretácico. La actividad volcánica propia del Cinturón Volcánico Mexicano comenzó en esta zona durante el Mioceno Temprano con la formación de un estratovolcán (30x15 km) constituido por rocas andesíticas calcialcalinas. Para el Mioceno Medio (12 Ma), un cambio importante en la . actividad volcánica del edificio provocó la formación de una caldera denominada "Las Tres Chicas", la cual tiene un diámetro de 30 km aproximadamente. La actividad post-caldérica consistió de tres eventos eruptivos de resurgencia dómica que ocurrieron hace 12 Ma, 5 Ma y 0.5 Ma respectivamente. Cada evento estuvo caracterizado por la intrusión de domos dacíticos y la generación de flujos piroclásticos que se emplazaron en el interior del recinto calderico, y por la emisión de flujos de lavas pericaldéricos. La periodicidad de la actividad volcánica, la presencia de domos relativamente jóvenes (e.g. Cacique) y la actividad sísmica registrada en la zona, son evidencias que sugieren que el Complejo Volcánico de Zitácuaro debe ser considerado como un área potencialmente activa.Universidad Nacional Autónoma de México.
