The Burgess Shale is a series of sediment deposits spread over a vertical distance of hundreds of metres, extending laterally for at least 50 kilometres (30 mi). [18] The deposits were originally laid down on the floor of a shallow sea; during the Late Cretaceous Laramide orogeny, mountain-building processes squeezed the sediments upwards to their current position at around 2,500 metres (8,000 ...
[11] [2] Typically raw oil shale particles between 12 millimetres (0.5 in) and 75 millimetres (3.0 in) in size are fed into the top of the retort and are heated by the rising hot gases, which pass through the descending oil shale, thereby causing decomposition of the kerogen at about 500 °C (932 °F) . Shale oil mist, evolved gases and cooled ...

The Piceance Basin contains one of the thickest and richest oil shale deposits in the world and is the focus of most on-going oil shale research and development extraction projects in the U.S. The Piceance Basin has an estimated 1.525 trillion barrels of in-place oil shale resources, and an estimated 43.3 billion tons of in-place nahcolite ...
The oil shale descends the retort as a moving bed. [1] [14] The oil shale is heated by the rising combustion gases from the lower part of the retort and the kerogen in the shale decomposes at about 500 °C (932 °F) to oil vapour, shale oil gas and spent shale. Heat for pyrolysis comes from the combustion of char in the spent shale.
Oil-shale deposits in Morocco. Morocco's total oil shale resources are estimated to contain 53.381 billion barrels (8.4869 × 10 ^ 9 m 3) of shale oil. [1] 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. [2]
