Quick Summary

Organic geochemistry is the study of organic compounds found in geological materials and meteorites, including those with potential biological origins. It is a branch of geochemistry that explores topics such as the origin of petroleum and life itself. Organic chemical reactions play a role in many geochemical processes, including rock weathering, soil production, and the transformation of sediments into sedimentary rocks.12

The field also investigates the nature and chemical transformations of biological material present in deposits like coal, petroleum, and natural gas. Understanding these processes is crucial for comprehending Earth's history and the cycles of elements within its systems.23

…aspects of geochemistry, generally termed organic geochemistry and biogeochemistry. Major problems of organic geochemistry include the question of the chemical environment on Earth in which life originated; the modification of the hydrosphere, and particularly the atmosphere, through the effects of life; and the incorporation of organic materials in rocks, including
