The Origin of Petroleum: Abiogenic Processes or Organic Matter?

This research aims to determine whether petroleum is formed through abiogenic processes deep within the Earth or from sedimentary organic matter. It explores geochemical evidence such as carbon isotopes, optical activity, and biomarkers found in organic-rich shales.
