Abstract
The High-Moulouya granites from Aouli and Bou-Mia contain magmatic str uctures, generated during emplacement in the crust, which provide evid ence for laccolithic injection. The first magmas, injected along norma l faults, were gabbroic in composition and cause a partial melting of pelitic country-rocks. Evidence for magmatic mixing is provided by var ious enclaves in the granitoids. Granitoid emplacement in the oriental Meseta occurred in structural transtensional environment, compatible with the structures of the occidental Meseta.
