Oil shale in Morocco represents a significant potential resource. The ten known oil shale deposits in Morocco contain over of shale oil. Although Moroccan oil shale has been studied since the 1930s and several pilot plants have extracted shale oil from the local formations, commercial extraction was not underway as of 2011. ==Reserves== Morocco's total oil shale resources are estimated to contain of shale oil.〔 According to the United States Department of Energy, the oil shale deposits in Morocco constitute about 3.5% of the world's known oil shale resources.〔 〕 There are ten known oil shale deposits in Morocco.〔 〕 Most of the local deposits were laid down during the Upper Cretaceous era and are marinites. The most important of these are located at Tarfaya (in the south-westernmost part of Morocco) and Timahdit (in the Middle Atlas Mountains).〔 〕 The largest known oil shale deposit in Morocco is located at Tarfaya. The deposit is estimated to consist of 80 billion tons of oil shale, containing of shale oil.〔 The deposit is divided into two flanks on each side of Tazrha ''sabkha''. The volume of the west flank area is over ; the east flank area's volume is over .〔 The average depth of the formation is . Its moisture content is about 20% and its sulfur content is about 2%. It yields about of shale oil per one ton of oil shale.〔 〕 The second largest deposit is located at Timahdit, about southeast of Rabat.〔 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 third largest deposit, consisting of , is located near Tanger. The deposit is estimated to contain of shale oil. The oil shale formation's maximum thickness is . It yields of shale oil per one ton of oil shale.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Oil shale in Morocco」の詳細全文を読む スポンサード リンク
