Abstract：The deep source material mainly enters the sedimentary rock through volcanic activity or hydrothermal activity. The lower member of Xiguayuan Formation in Luanping Basin is a set of fine-grained sedimentary rocks affected by deep source material,so thin section observation and geochemical analysis were carried out to study the influence of deep source material on the environment and hydrocarbon accumulation in the study area. The results show that the deep source material in the lower member of Xiguayuan Formation mainly entered the sedimentary rocks through underwater volcanic eruptions and hydrothermal jet activities. Through the variation law of environmental indicators(Th/U,V/Cr,V/(V+Ni),CIW,Sr/Cu,etc.),it is found that hydrothermal jet activities have frequent and severe short-term effects on the environment,while underwater volcanic eruptions have occasional,weak long-term effects on the environment. By comparing the organic-rich layer with the hydrothermal strength index((Fe+Mn)/Ti,Al/(Al+Fe+Mn)),it is found that the organic-rich layer has high value of (Fe+Mn)/Ti,low value of Al/(Al+Fe+Mn)characteristics. According to the above studies,the participation of deep source materials has greatly improved the ancient productivity,and its eruption and jet flow mechanism has made the water body anoxic and stratified,providing good preservation conditions for organic matter.
