Intercalación de un sistema turbidítico siliciclástico entre carbonatos de plataforma: implicaciones tectónicas (Aptiense-Albiense, cabo Ogoño, Bizkaia)

Abstract

A turbidite (channel-levee) siliciclastic system replaced vertically a mixed carbonate and terrigenous platform, and it in turn was replaced by litoral sandstones and bank carbonates (Aptian-Albian, Ogoño, Bizkaia). An E-W composite stratigraphical section shows that an inversion in subsidence tool< place approximate/y around the Ibarrangelua N-S paleogeographic line during the process. Therefore, the action ofa deep-seated, probab/y wrench fau/t is invoked to account for the origin ofthe turbidite system in this unusual context
