Environmental impacts of oil shale Oil shale can be extracted via surface, underground, or "in-situ" mining, in which kerogen is heated underground and pumped to the surface. All these techniques demand significantly more energy than what's required for conventional liquid oil, producing more air and global warming pollution as a result.

Named by. James Hall, 1839. The Marcellus Formation or the Marcellus Shale is a Middle Devonian age unit of sedimentary rock found in eastern North America. Named for a distinctive outcrop near the village of Marcellus, New York, in the United States, [3] it extends throughout much of the Appalachian Basin.This property is called fissility. [1] Shale is the most common sedimentary rock.
