The GIS-Based Mineralising Factors Appraisal Of Copper In The Lancang River Area Of Yunnan Province

The Lancang River area in Yunnan Province is our workaround ,which is geotectonically belonged to the Tri-River Deposit Zone. In this study, we have collected a mass of pertinent data, such as the geological ,the mineral,the geophysical and the geochemical,etc., Then researched the regular pattern of the mineralizing in this area. The spatial databank was built through GIS, which was used in mineral prediction. The fuzzy logic overlay analysis module was improved. And I successfully acquired the advantage blocks of the mineralising factors in this area.
