- •
Isotopic and molecular compositions of coalbed methane and production waters in karstic collapse column area, northern Qinshui basin were analyzed.
- •
Karstic collapse columns can make carbon isotopes of CH4 and CO2 heavier in northern Qinshui basin.
- •
Thermogenic methane is dominant in Taiyuan Formation of northern Qinshui basin, mixed with minor amounts of biogenic gases.
