| 摘 要： | 吉家洼金矿床是一个产于熊耳山金矿田内的中小型金矿床，属于构造蚀变岩型金矿床.通过对吉家洼金矿床地质特征及围岩蚀变特征的研究，认为该矿床金矿化与硅化、黄铁矿化关系密切，金的载体以金属硫化物为主.围岩蚀变分带较明显，与金矿化密切相关，蚀变带中心位置金矿化最强.

| Abstract: | The small-medium sized Jijiawa gold deposit of tectonic altered rock type is located in the Xiong'ershan gold field. Research on the geology and wallrock alteration of the deposit shows that the gold mineralization is closely related to silicification and pyritization. The gold carrier is dominated by metal sulfides. The wall rock alteration zoning,with strongest gold mineralization in the center,is obvious. |
