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 ...

After the Burgess Shale site was registered as a World Heritage Site in 1980, it was included in the Canadian Rocky Mountain Parks WHS designation in 1984. In 2012, the discovery was announced of another Burgess Shale outcrop in Kootenay National Park to the south. In just 15 days of field collecting in 2013, 50 animal species were unearthed at ...
Shale is characterized by its tendency to split into thin layers less than one centimeter in thickness. This property is called fissility. [1] Shale is the most common sedimentary rock. [2] The term shale is sometimes applied more broadly, as essentially a synonym for mudrock, rather than in the narrower sense of clay-rich fissile mudrock. [3]
Mitchell was born to Greek immigrant parents in the port city of Galveston, Texas in 1919. [2] His father, Savvas Paraskevopoulos, was from the village of Nestani in Arcadia, tended goats before immigrating to the United States in 1901, arriving at Ellis Island at the age of 20. He worked for railroads, and gradually moved west.
[citation needed] Moreover, FMG is also rich in coalbed methane resources that total around 8.9 billion cubic metres (310 billion cubic feet). [3] However, there is a great risk for FMG to run the non-coal business for whose management system is a very state-owned company style.
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.
