Timahdit oil shale deposit
The Timahdit oil shale deposit is an oil shale deposit located about southeast of Rabat near Timahdite, Fès-Meknès, Morocco. It is the second largest oil-shale deposit in Morocco. Geologically, it comprises two basins: "El koubbat" and "Angueur" synclines. The oil shale formation is about long and wide. The volume of the "El koubbat" syncline formation is about ; the "Angueur" syncline area is about . The deposit is estimated to consist of 42 billion tons of oil shale, containing of shale oil. The oil shale formation's thickness varies from . Its moisture content is 6–11% and  sulfur content is about 2%. On average it yields of shale oil per one ton of oil shale. As the Timahdit deposit is located near Ifrane National Park and Haut-Atlas Oriental National Park, oil extraction is an environmentally sensitive issue. The Timahdit deposit was discovered during the 1960s. The deposit was researched and tested during the 1970s and 1980s. The Moroccan Office of Hydrocarbons and Mining (ONHYM) developed and tested a shale oil extraction process called T which in 1984–1986 produced approximately 400 tons of shale oil at Timahdit.
