Geochemical characteristics of abiogenic gas and its percentage in Xujiaweizi Fault Depression, Songliao Basin, NE China
Gases with different origins occur in the Xujiaweizi Fault Depression. Among them, the abiogenic gases have a typical carbon isotopic reversal trend (δ13C1>δ13C2>δ13C3>δ13C4), the carbon isotope of methane greater than −30.0%, and the R/Ra greater than 0.5. According to the simulative calcu...
