Deformaciones recientes en el frente de la Cordillera Rifeña (Prerif, Marruecos)

Abstract

The Prerif ridges form pari of the foreland of the Rif Mountains. They are formed by superposed slices, with folds and faults, originated during the late Miocene WSWwards displacement of the Prerif units. At present, they thrust over the Plio-Quaternary formations of the Sa/'s and Charb basins. The analysis of the deformations in the Prerif ridges and the Plio-Quaternary lacustrine formations of the Sai'ss basin, as well as the thrust structures, indicates a recent tectonics with a N-S to NW-SE compression, subparallel to the trend of the present Iberian-Africa convergence
