摘要：

Three Mesozoic anorogenic magmatic episodes have affected the Moroccan Haut-Atlas. The Triassic transitional to tholeiitic episode indicates an incipient distensional regime and was produced by partial low melting of a sub-continental mantle with crustal contamination. The Lower Liassic episode was marked by continental tholeiites produced by a higher rate of partial melting of the sub-continental upper mantle. The Jurassic-Cretaceous alkaline episode resulted from a small degree of partial melting of a different mantle source.
