WOil sands, tar sands, crude bitumen, or bituminous sands, are a type of unconventional petroleum deposit. Oil sands are either loose sands or partially consolidated sandstone containing a naturally occurring mixture of sand, clay, and water, soaked with bitumen, a dense and extremely viscous form of petroleum.
WBemolanga is a large oil sands deposit in the onshore Morondava Basin of Madagascar. The deposit was discovered in the early 1900s but was known to locals for centuries.

WMerkwiller-Pechelbronn is a commune in the Bas-Rhin department in Grand Est in north-eastern France.
WOil sands tailings ponds are engineered dam and dyke systems used to capture oil sand tailings. Oil sand tailings contain a mixture of salts, suspended solids and other dissolvable chemical compounds such as acids, benzene, hydrocarbons residual bitumen, fine silts and water. Large volumes of tailings are a byproduct of bitumen extraction from the oil sands and managing these tailings is one of the most difficult environmental challenges facing the oil sands industry.
WThe Orinoco Belt is a territory in the southern strip of the eastern Orinoco River Basin in Venezuela which overlies the world's largest deposits of petroleum. Its local Spanish name is Faja Petrolífera del Orinoco.
WTar Sands Blockade is a grassroots coalition of affected Texas and Oklahoma people and climate justice organizers who use peaceful and sustained civil disobedience to stop the Keystone XL tar sands pipeline. Tar Sands Blockade has utilized non-violent direct action to stop construction of the pipeline throughout East Texas including banner drops, lockdowns, and tree sits.

WIn the United States a large supply of oil sands are found in Eastern Utah. These deposits of bitumen or heavy crude oil have the ability to generate about 12 to 19 billion barrels from a number of prominent sites.
