摘要: The baseline methane for shallow groundwater can provide an important evidence to interpret possible stray associated with shale gas exploration. This study investigated and traced content its origin of in a karst aquifer the Fuling block, SW China. results show that contents are all less than 0.01 mg L−1 volumetric dissolved ranges from not detected 0.0064%. δ13C-CH4 −74.4 −49.1‰, suggesting biogenic origin. For first time, 3He/4He end-numbers were determined.
