A geophysical investigation of the southern Jalisco block in the State of Colima, Mexico

Abstract

Geological mapping and potential field studies in the State of Colima, Mexico, were conducted to study previously interpreted neotectonic extension across the Colima graben. Little, or no, extension has occurred south of Volcan de Colima and that the features previously inferred to be extensional structures are instead erosional landforms related to older deformation and downcut streams due to rapid sedimentation from Volcan de Colima. -Authors
