Question

Quizplus · Accepted Answer

Kerogen is a type of organic substance that is found in black organic shales at temperatures below the oil window. It is a precursor to crude oil and natural gas and can be converted into these hydrocarbons through processes such as thermal maturation. Coal, on the other hand, is formed from different types of organic matter (such as plant material) and is typically found at greater depths and higher temperatures than black organic shales. Keratin is a protein found in hair, nails, and other animal tissues but is not related to the formation of hydrocarbons.
