serpentinite, peridotite, orthopyroxe~ite, metagabbros, fine-grained diorite and YOQnger gabbros cover a considerrable·part of the studied area of EI-Genena El-Gharbia.

Systematic sampling of the different rock unites was carried out from the exposed outcrops a~d drilled borehols.
The petrographic study were corroborated by complete chemical analysis of representative s&~ples from the most cownon rock types. Semi-qua~titative spectrographic anaalysis was also carried OQt for some hundred rock samples.
