| 摘 要： | 长塘岭钨多金属矿区的土壤地球化学特征表明，该区W、Sn、Bi等高温成矿元素异常强度低，规模小，吻合性差；而Mo、Pb、Zn、Cu等，尤其是Mo的异常强度高，规模大，且吻合性较高，具有较好的找矿潜力。该区成矿元素异常主要受似斑状黑云母二长花岗岩与二云母钾长花岗岩的接触带控制，为含矿热液沿不同岩性接触带充填交代引起的异常。

| Abstract: | Soil geochemical characteristics of the Changtangling tungsten polymetallic ore district show that anomalies of high temperature elements such as W,Sn and Bi are weak,relatively small and rather inconsistent,whereas anomalies of such elements as Mo,Pb,Zn and Cu are characterized by high intensity,large scale and consistency,suggesting fairly good ore-prospecting potential.The anomalies of ore-forming elements are mainly controlled by the contact zone between the porphyroid biotite adamellite and the two-mica K-feldspar granite and were formed by the filling and replacement action of the ore-bearing hydrothermal fluid along the contact zone between rocks of different lithologic characters. |
