| Abstract:The Panan Cu-Mo-W deposit is located in the Zedang ore field on the eastern section of the Gangdese metallogenic belt in Tibet. It has
favourable geological conditions for hosting large-scale porphyry and skarn Cu-Mo-W mineralization. The short wave infrared spectrum mineral analyser
(BJKF-1), made by the Nanjing Zhongdi Instruments Company Ltd, was applied to undertake the alteration mineral mapping at the Panan. Phyllic and
propylitic alteration are identified at the surface, with locally developed argillic alteration which is clearly structurally controlled and is supergene. Based
on the alteration zoning and the geochemical data, it is interpreted that the south-western part of the mapping area is very likely to be the centre of the por鄄
phyry mineralization. Drilling is recommended to test the centre of the phyllic alteration, and drill hole PZK701 intersected four mineralization zones. |
