Resumen:
Stratigraphy and structure of the central sector of the Mexican Volcanic Belt and adjoining areas were investigated in order to evaluate its Plio-Quaternary tectonic evolution, the stress directions, and their relative values. Three main periods, characterized by different mechanisms of deformation limited to the MVB area, may be grouped in a single deformation cycle. The kinematics and the uniformity of the stress trajectories during Plio-Quaternary times suggest plate tectonic control and a passive mode of rifting. In this framework the large amount of magma extruded is believed to be produced by a thermal anomaly induced by the rifting and affecting also the subducted slab. -from Authors
