摘　　要：为明确涪陵焦石地区悦来冒气点气体来源,分别由三家权威机构对4个冒气点进行取样,同时进行三个分析测试项目的测定,将所测得的结果进行分析比对。综合分析,冒气点的气体与涪陵龙马溪组气体差异较为明显,与茅口组具有很强相似性。因此,分析研究认为冒气点气体来源于二叠系茅口组。To ascertain the origin of the gas emissions at the gas vent points in Yuelai,Fuling,within the Jiaoshidaba area,samples were taken from four vent points by three authoritative institutions.Concurrently,measurements were conducted across three analytical test projects,and the acquired results were compared and analyzed.Comprehensive analysis revealed notable differences between the gases at vent points and the Fuling Longmaxi Formation gases,but showed strong similarities with the ones of the Maokou Formation.Consequently,the study concludes that the gas emitted from these vent points originates from the Permian Maokou Formation.
