The Green River formation of this mineral is a potential source of crude oil.
Albertite is a type of asphalt formed from this type of mineral. The Green River formation of this mineral is a potential source of crude oil. Types of this argillaceous mineral include the "black" type, which contains a large amount of carbonaceous material and is also especially rich in organic material. It is similar in composition to marl and (*) mudstone, containing clay minerals and silt-sized fragments of other minerals, but unlike mudstone, it is highly fissile, splitting easily along cleavage lines. Over the last decade, the use of fracking to obtain natural gas from formations of this mineral has become increasingly common. Metamorphism can turn this mineral into slate.
