Abstract:

Based on chemical composition and stable carbon isotope data, this pa-per discusses the origin of CO2N2,He and gaseous hydrocarbon in SanShuiBasin, Guangdong Province. The CO2 mainly comes from deep-earth,N2 is the product of biochemical process and He is the product of the decay of radio-element. Gaseous hydrocarbon includes biochemical methane and thermodegr-adation hydrocarbon gas.
