Principal methane sources are

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

• Outgassing from earth's mantle through mud volcanoes
• decomposition of organic wastes
• natural sources (marshes): 23 %
• mineral fuel extraction: 20 %, see Coal bed methane extraction

Methane reacts with oxygen in volcanic areas and become carbon dioxide.

Methane is extracted from geological deposits as a mineral fuel which is associated with other hydrocarbon fuels sometimes accompanied by helium and nitrogen.
