| 摘 要： | 乌拉根铅锌矿床位于新疆喀什凹陷北部,矿区及外围发育大量有机物质,有机质与铅锌成矿的关系备受关注。文中采用有机质抽提、族组分分离、定量及饱和烃色谱-质谱等实验分析方法对铅锌矿区有机物质及外围油砂中氯仿沥青"A"和生物标志物进行分析,研究铅锌矿区及外围有机质特征及其地质意义,并对有机质与铅锌矿化的关系进行了探讨。结果表明,近矿围岩和外围油砂中氯仿沥青"A"族组成及其饱和烃的主要生物标志物特征均较相似,CPI=1.11～1.17,Pr/Ph=0.68～1.08,C27、C28、C29规则甾烷具有C27>C28 |

| Abstract: | 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 |
