| Abstract | Petrographic and geochemical zonation of a basic enclave in a magmatic breccia of N'Kob sector (south-eastern Siroua, central Anti-Atlas, Morocco). The study of a basic enclave and its Proterozoic enclosing granodiorite in the N'Kob area, shows the existence of a petrographic and geochemical zonation wich results from different physical and chemical processes which, first occurred between magmas, and afterwards between rocks. These processes are thermal diffusion, reflected by sinuous contacts between the host-rock and the enclave, fine-grained margins, and limited and selective chemical diffusion. |
