El Magmatismo Básico en La Cuenca Fameno-Dinantiense de Sidi Bettache (Marruecos Hercínico Noroccidental): Nuevos Datos

Abstract

Commonly is held up that the Sidi Bettache Basin corresponds to the collapse of a large block of the middle Devonian carbonate platform with subsequent magmatic injections emplacement along its boundaries. Previous studies of one of us (A.L.) and those in progress show instead that this magmatism is primarily controlled by distensional activity of NNW-SSE to NW-SE faults before Middle Visean time. These faults affect throughout the 60 km wide western part of the basin which is also characterized by its Famennian-Lower Visean sedimentary evolution and by a complex variscan polyphasic structuration
