| 摘 要： | 白云金矿是辽东青城子矿田的一处大型金矿床，矿体赋存于辽河群盖县组碎屑岩中，受白云EW向断裂控制。构建矿床地球化学异常分带模型，总结找矿预测标志，有助于开展深部及矿区外围的找矿预测。通过对白云金矿床不同中段微量元素与烃类组分的含量变化及其在矿体周围的异常展布特征和富集规律进行分析总结，得出该矿床原生晕分带序列为：Hg、烃类（前缘晕）→As、Sb（矿头晕）→Au、Ag、Cu、Pb、Zn（近矿晕）→Co、Ni、Mo、Bi、Mn（尾晕）。研究表明，白云金矿床向深部仍有一定的找矿空间，矿床地球化学异常分带模型对区域上寻找同类型矿床具有一定的参考价值。

| Abstract: | Baiyun gold deposit is a large gold deposit located in Qingchengzi ore field of Liaoning Province.The orebodies occurred in the clastic rock of Gaixian Formation of Liaohe Group，controlled by Baiyun EW trending fracture.It is helpful to carry out deep and peripheral prospecting prediction by establishing geochemical anomaly zoning model and summarizing exploration indicators.The content changes of trace elements and hydrocarbon components in difference mid-section and its abnormal distribution characteristics and enrichment regularityaround orebody of Baiyun gold deposit was also summaried.It is concluded that the deposit for the primary halo zoning sequence：Hg、hydrocarbon（front halos） →As、Sb（ore roof halos） →Au、Ag、Cu、Pb、Zn（near to ore halos） →Co、Ni、Mo、Bi、Mn（tail halos）.Research shows that it is still has a certain space for prospecting in deep of the Baiyun gold deposit，ore deposit geochemical anomaly zoning model has a certain reference value for looking for the same type deposits on the area. |
