摘要
吉家洼金矿是熊耳山地区一个构造蚀变岩型金矿床。Ａｕ的丰度由区域—矿区—构造岩—矿体呈几何级数递增。矿体中Ａｕ与ＳｉＯ２相关，与亲硫元素和重矿化剂元素强相关，元素具明显的轴向分带。矿体不同部位的元素组合和元素对比值具指示意义。矿体头部中低温和高温元素共存，显示多期次叠加矿化特征，指示矿体有大的延深。
Jijiawa gold deposit is an altered tectonic breccia type gold deposit in Xiongershan area, the abundance of Au element increases in geometric progression from the region to ore field,tectonic belt, to ore bodies. Au is correlated to SiO 2 and close correlated to sulfophile elements and heavy mineralizer elements in ore bodies. Elements are axial zoning obviously. Paragenetic association of elements and elementsratios in different location of orebody have indicating signification. The co existing of middle low and high temperature elements in the tops of the ore bodies shows the multi stages superimposed mineralization, indicating ore bodies longly down ward extension.
