Control tectónico sinsedimentario de la serie estratigráfica del sector de Güeñes (Albiense, Bízkaia)

Abstract

Careful geological mapping and cross section logging o f the Low er-Middle A lbia n succesios in the Guehes area resulted in the discovery of a unknown synsedimentary fault (Saratxaga). The fault had an extensional regime, and the easterly downthrown block recorded the coarsest and thickest sedimentary sequences. The N-S oriented fault originated within a complex strike-slip fault system that defines a small pull-apart sub-basin
