摘　　要：大秃顶子金矿床是改变找矿思路后在老锑矿区找金的突破,金与锑异位共生,在锑矿化系统倾斜延深发现金矿体。本文通过对金矿石成分、结构、构造等特征研究,结果表明该矿床矿石结构、构造比较简单,组分相对单一,是一个与银相伴生的含金构造蚀变岩型金矿床。随着对地质规律认识的总结和认识提高,丰富了二道甸子区金矿类型,为在古生界二叠系东南岔组层间构造中寻找金矿提供了依据。The Datudingzi gold deposit is a breakthrough in the old antimony mining area after the change of prospecting strategy. Gold and antimony coexist and are not in the same position,gold ore body was found in antimony mineralization system. Through the study on the composition,structure and tectonics of gold ore,the results show that the ore structure and tectonics of the deposit are relatively simple and the composition is relatively single. It is a gold-bearing structural altered rock type gold deposit associated with silver. With the summary and improvement of understanding of geological laws,the regional gold deposit types in Erdaodianzi area have been enriched,which provides a basis for searching for gold deposits in the interlayer structure of Dongnancha Formation of Paleozoic Permian.
