Organic geochemistry

This article is about the subject organic geochemistry. For the academic journal, see Organic Geochemistry.

Organic geochemistry is the study of the impacts and processes that organisms have had on the Earth. It is mainly concerned with the composition and mode of origin of organic matter in rocks and in bodies of water.[1] The study of organic geochemistry is traced to the work of Alfred E. Treibs, "the father of organic geochemistry."[2] Treibs first isolated metalloporphyrins from petroleum. This discovery established the biological origin of petroleum, which was previously poorly understood.[3] Metalloporphyrins in general are highly stable organic compounds, and the detailed structures of the extracted derivatives made clear that they originated from chlorophyll.
