Quizplus · Accepted Answer

Kerogen is an organic substance that is found in black organic shales at temperatures below the oil window. It is a precursor to oil and natural gas and requires further heating and pressure to transform into these energy sources. Gold and keratin are not typically found in organic shales, and while coal is also an organic substance, it forms from different geological processes and at different temperatures than kerogen.
