Permian volcanic Chougrane-El Had the Bouhsoussène complex (central Morocco), manifested primarily by volcanic rocks rhyodacites nature and basalt intercalated in the clay-greso-conglomeratic permian deposits. These are rocks texture in general microlitic to porphyry. Basalts consists of a primary paragenesis formed of plagioclase, pyroxene, olivine and quartz and a secondary mineral assemblage consisting of muscovite, calcite, chlorite and quartz. The rhyodacites show primary paragenesis formed of plagioclase, pyroxene and quartz and a secondary mineral assemblage consisting of calcite and sericite. Petrographic characteristics of these rocks are comparable to those of the Permian volcanic complex Khénifra and Tiddas-Sebt Ait Ikkou (Central Morocco). Area Chougrane-El Had the Bouhsoussène created on intracontinentale tear in the Asturian phase (Michard, 1976) recorded three volcanic episodes, two major eruptive episode and a third in vein deposit mode.

The AguelmamAzegza lake is located in the Middle Atlas mountain range, this region consists of carbonate rocks of Lias. It is the best-watered and richest region in Morocco in terms of wetlands, especially natural lakes, rivers and fresh springs. The lake’s water supply is ensured by the inflows of water in the form of underwater sources fed by precipitation (rain and snow) following tectonics and the genesis of karstic formations by the dissolution of carbonate rocks. The declining trend in lake levels in recent years results from the decrease in precipitation which decreases during these years.
