| 1. | From the characteristic of district geochemistry , we can figure out , cu , ag , pb , zn abnormality main spread along the west branch river set and close to border layer , and the rock chemistry analysis prove , west branch river set have the higher ag chemical element abundance , the cu have the characteristic of asymmetry distribute , and display the migration of element in the late multiphase tectonic activity
从区域地球化学特征可以看出， cu 、 ag 、 pb 、 zn等元素异常主要沿西岔河组及相邻层位分布，岩石化学测量证明，西岔河组在区域上具有较高的ag元素丰度值， cu元素具不均匀分布特征，显示出元素在后期的构造活动中的活化迁移。 |
