摘要
Wulagen zinc-lead deposit in Xinjiang Province is located in north margin of Kashi sag.Large quantity of organic matter exists in the mining area and the periphery of Wulagen zinc-lead deposit,and the relationship between organic matter and zinc-lead mineralization has attracted the attention.By the organic extraction,family components separation and quantitative,saturated hydrocarbons chromatogram-mass spectrum,the chloroform bitumen "A" and biomarkers were analyzed,and the characteristics of the organic matter and its geological significances and the relationship between organic matter and zinc-lead mineralization were discussed.The chloroform bitumen"A" family components and main eigenvalues of biomarkers in the wall-rocks and the periphery of Wulagen zinc-lead deposit have a similar and smaller variational range(CPI=1.11-1.17;Pr/Ph=0.68-1.08;C27,C28 and C29 sterane has a pattern of C27>C28
