摘要
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 lithologie characters.
