| 摘 要： | 本文将豫、陕熊耳群火山岩的岩石学特征、地球化学特征、形成的构造环境等方面详细对比，总结了豫西熊耳群中金矿的矿床类型、分布规律、成矿物质来源及控矿构造等地质特征，并将其与陕西熊耳群相比较，认为缺失下熊耳群许山组陆相大山岩这一重要含金层位和成矿层位是陕西熊耳群中缺乏大型金矿床的主要原因，同时，从成矿物质来源的多源性、控矿构造的相似性对陕西熊耳群的找矿方向和前景作了分析。

| Abstract: | The detail comparison of the rocks, geochemistry and. tectonic environrnent for Xiongergroup have been made between the west Henan and Shaanxi. The gold deposit types, distribution, source bed, ore-controlling structure and other geological characteristics of west of Henan are summarized. It is concluded that the main reason of short of large gold deposits is due to little lacuua in the lower Xionger group. Having comparied the source bed and similarity of ore-controlling tectonics, the potential source and prospecting in Shaanxi are analysised in this paper. |

| Keywords: | the Xionger group source bed ore-controlling structure detachment fault |
