Definition
Oil shales are fine-grained sedimentary rocks formed in many different depositional environments (terrestrial, lacustrine, marine) containing large quantities of thermally immature organic matter in the forms of kerogen and bitumen . If defined from an economic standpoint, a rock containing a sufficient concentration of oil-prone kerogen to generate economic quantities of synthetic crude oil upon heating to high temperatures (350–600 °C) in the absence of oxygen (pyrolysis ) can be considered an oil shale.
Introduction
The term oil shale is often described as a misnomer, in that the organic component is primarily kerogen, not oil and the mineral matrix is not necessarily clay mineral-rich, but can include a variety of different phases (Miknis and McKay 1983). Oil shales are essentially a type of petroleum source rock, the key differences being that: (1) oil shales have...
