| Abstract: | It is held that the CO2 gas pools in Songliao Basin are mainly of mantle origin by the analysis of the components,the carbon isotope composition and the helium isotope composition of the gas in ten CO2 gas pools found.The main characters of the CO2 gas pools are δ13CCO2>-8‰ and R/Ra=1.9~7.2.The analysis of geological background and fluid inclusion indicates that the CO2 pools in Changling,Dehui and Gulong fault depressions are mainly formed lately.The reasons are as follows:Firstly,the CO2 inclusions are late period fluid inclusions,which distributes in the cracks of transecting quartz grain or transecting widen quartz.Their homogenization temperature is 120~140 ℃.So,the forming stage of CO2 may be mainly between 72 Ma and 48 Ma.Secondly,the formation and distribution of CO2 is related to many kinds of faults,including lithosphere faults,crust fractures,basement rifts and overburden faults,especially related to NE-NNE deep faults which have strike slip motion in late stage.These kinds of faults mainly control depression formation in early stage and have NE-NNE left-lateral strike slip motion in late stage.Also,volcano erupted with amazing amount of CO2 in this stage and the faults became the migration channel of the CO2 ,which prompted the formation of the CO2 pools. |
