A Paleomagnetic Constraint on the Late Cretaceous Paleoposition of Northwestern Baja California, Mexico

Abstract

We present palaeomagnetic data for Cretaceous sedimentary rocks from the El Rosario formation of northwestern Baja California which imply a northward displacem.ent of 15.0 .± 3.8' and a 30.8 ± .4.2" clockwise rotation for the Baja Peninsula relative to the North Amencan craton smce Late Cretaceous time. Paired IRM acquisition, X -ray diffraction, and… (More)
