The study of the Neogene sequences outcropping in the La Purisma area, Baja California Sur, Mexico, has demonstrated the presence of regional unconformities separating the main sedimentary bodies. On the basis of stratigraphic and structural analyses, we propose a new stratigraphic framework in terms of depositional sequences. The combined analysis of the stratigraphic and tectonic evidences is consistent with complex active wrenching along the Pacific margin. -from Authors

Abstract
The study of the Neogene sequences outcropping in the La Purisma area, Baja California Sur, Mexico, has demonstrated the presence of regional unconformities separating the main sedimentary bodies. On the basis of stratigraphic and structural analyses, we propose a new stratigraphic framework in terms of depositional sequences. The combined analysis of the stratigraphic and tectonic evidences is consistent with complex active wrenching along the Pacific margin. -from AuthorsI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
