Abstract

Summary

Analysis of the subsidence evolution of the Central High Atlas basin, coupled to geochemistry of some REE, shows that this rift “failed” in Late Jurassic times most probably due to differential extension, the mantle being more stretched than the crust as suggested by volcanism, leading to uplift as predicted by non-uniform extension models. The thermal dome may have been active since that time. The straightforward implications are that any thermal evolution models should take into account the lithospheric evolution and the complex geodynamic history of the CHA.
