摘　　要：通过对辽宁白云金矿区典型的Ⅰ-1号金矿体11线的地表及井下不同标高进行系统采样,分析各指标异常在空间上与金矿体之间的对应关系,弄清白云地区地表土壤次生晕与坑道原生晕的关联性,发现烃气测量法在辽宁景观条件下完全适用,总结出了本区进行找矿预测的地质和地球化学找矿标志。通过对姚家岭北部地区进行烃类组分及部分微量元素异常展布特征分析,并结合异常分布区的地质条件进行了综合找矿潜力评价,圈定了相关找矿有利区。The authors systematically collected samples from the surface of the 11 prospecting lines aboveⅠ-1 ore body and from dif-ferent elevations in theⅠ-1 ore body within the Baiyun gold deposit, Liaoning Province. Analysis of the correspondence between the spatial distribution of the abnormal indexes and the ore body was conducted so as to reveal the relationship between the secondary halos and primary halos. It is found that the hydrocarbon technique can be used in this area. In this paper, the authors summarized the geo-logical and geochemical prospecting criteria of this area. By analyzing the hydrocarbon components and the abnormal distribution of some trace elements in northern Yaojialing together with the geological conditions of the abnormal areas, the authors made a comprehen-sive evaluation of prospecting potential and delineated the prospective areas.
