Structure, cinématique et chronologie des déformations dans la dorsale du Haouz (Rif, Maroc)

Abstract

The complex thrust-slice structure of the Haouz Mountains was formed during the Neogene in several phases, in which we recognize: a- Paroxysmal tectonic events, occurred in the Early Miocene, responsible of the formation of the thrust slices verging towards the W and SW as well as backthrusts verging towards the E and NE. These backthrusts appeared after the blockage of the thrust slices by the Fiysch nappes situated in a more external position, and are interpreted as antiformai stack phenomena. b- Post - paroxysmal tectonic events with lesser importance, alternating as distensive and compressive phases, occurred during the Middle and Late Miocene
