| 摘 要： | 阿舍勒铜锌矿床原生晕和次生晕均受矿体、中泥盆统阿舍勒组第二岩性段地层、近ＳＮ向一断裂控制。阿舍勒铜锌矿床的成矿、成晕作用是多期次的，其成矿、成晕直接（矿体）指示元素为Ｃｕ，Ｐｂ，Ｚｎ，Ａｕ，Ａｇ，Ｂａ等。前晕指示元素为Ａｓ，Ｓｂ，Ｈｇ等；尾晕指示元素为Ｓｎ，Ｍｏ等。利用这些异常元素的地球化学特征，不仅可确定该矿床的矿化类型和矿体剥蚀深度（或埋深），而且也可确定与该矿床相似的成矿靶区（即异常区），并对成矿靶区进行预测评价。

| Abstract: | The Primary and secondary haloes of copper-zinc deposit in Ashele are controlled by ore body,the seeond lithological section(D2as2)and nearly S-to-N fault.The mineralization and halo activities are of mulitphase.With diirect index elements of Cu,pb,Zn,Au,Ag and Ba,the fore-halo index elements include As,Sb,Hg and so on.and the back-halo index elements including Sn and Mo.The geochemical characteristics of above abnormal elements are used to determine the mineralization type erosion depth of ore body(or burial )and also t o determine the mineralization target(anomaly area)of similiar deposits,for the prediction and e valuation of mineralization target. |
