Indications of uranium have been identified in virtually all areas of the country, from the precambrian to the quaternary. They are essentially related, and vein type anticlines in precambrian granite (Anti-Atlas) and hercynian (High Western Atlas, Jebilet, Rehamna, Central Morocco, Morocco High Moulouya and North East).
Exploration for uranium is currently concentrated in the Anti-Atlas and the southern provinces.
Coal exploration in Morocco began early last century and were almost entirely focused in the coal regions, especially after the discovery of deposits of anthracite at Jerada in 1928.
Today, the regions of Morocco which are most favorable for the search for coal are the high plains and the Zag Basin.
