Isotope geochemistry was the key to determining that the hydrocarbon and hydrogen gases deep in Precambrian Shield rocks are produced not by conventional mechanisms but by abiogenic reactions.
However, this conclusion is now being reconsidered in the light of recent research demonstrating that abiogenic hydrocarbon formation via chemical reactions between water, dissolved inorganic carbon and minerals is not only capable of producing reduced organic carbon, but that this organic carbon is strongly isotopically depleted with respect to its inorganic source.
