Abstract

In this work we report a magnetostratigraphic study of a Pliocene section at Villarroya basin. The correlation with the Geomagnetic Polarity Time Scale (GPTS) is tied by the existence of a well-defined paleontological locality (M N 1 6 b ) at the top of the profile . This correlation allows us to calculate sedimentary rates which satisfactorily match the expected rates from local paleogeographyc studies. The main contribution of this study is the precise magnetostratigraphyc dating of both the Villarroya paleontological locality at Reunion magnetozone (2,229-2,197 m.y.) and, specially, the climatic sedimentary break (3,325-3,221 m.y.) which occurred at the boundary of the two. identified TectoSedimeptary Units (TSU).
