ABIOTIC METHANE ON EARTH

ABIOTIC METHANE ON EARTH

Over the last 30 years, geochemical research has demonstrated that abiotic methane (CH4), formed by chemical reactions which do not directly involve organic matter, occurs on Earth in several specific geologic environments. It can be produced by either high‐temperature magmatic processes in volcanic...

Zusammenfassung:Over the last 30 years, geochemical research has demonstrated that abiotic methane (CH4), formed by chemical reactions which do not directly involve organic matter, occurs on Earth in several specific geologic environments. It can be produced by either high‐temperature magmatic processes in volcanic and geothermal areas, or via low‐temperature (
