摘要
区域铜的高背景带为矿床的区域地球化学找矿标志，多宝山组一段为矿源层；由矿带内→外有Ｃｕ，Ｍｏ，Ａｇ→Ｐｂ，Ｚｎ的水平分带，矿体轴向分带为：（上）Ｓｂ－Ａｓ－Ｚｎ－Ｐｂ－Ａｇ－Ｃｕ－Ａｕ－Ｍｏ－Ｂｉ－Ｗ（下），属于正常序列；根据该序列统计了矿体前缘、矿体头部、矿体中部及矿体尾部的单元素、元素对比值、元素累加后比值判别标志。并建立了区域、矿田及矿床的地球化学找矿层次模型（Ｍ）。
The copper higher background zone and lower background zone are signs of regional geochemical exploration. Duobaoshan Group(O2d1) is the ore source bed. The horizontal zoning is, from its inner to outside, Cu-Mo-Ag→Pb-Zn. And the axial zoning is, from the top to the bottom of ore body,Sb→AS→Zn→Pb→Ag→Cu→Mo→Bi→W.It belongs to the ordinary succession. According to this succession, signs of different parts of ore bodies about single element, ratio of two elements ratio of elements after being plusing are given. The regional geochemical exploration level model of the ore field and the ore deposit has been set up.
