The Application Of Weights-of-Evidence To Assessment Of Mineral Resources Of Copper In East Tianshan Mountain Region

East Tianshan Mountains is located in the Talimu plate interface place with Kazakhstan- Jungar plate,this region occupies extremely important position in the process of Eurasian plate formation.This region have experienced a long range geologic process. Have formed the complicated geology phenomenon. Have the very rich mineral resources potential. It's a very important mineral resources perspective region in China's western part. In this region hold in store rich mineral resources, Over 50 kind mineral such as copper, nickel, gold, silver, iron, lead, zinc, manganese, petroleum, potassium compound coal. And, the ore concentrates kind relatively. Carrying out the assessment of mineral resources of copper in East Tianshan mountain region,To further strengthens the geological investigation. Have important practical or immediate significance to the sustainable development promoting mining industry economics in this area.By collects and sums up the prehominid's research results,make use of the ArcGis software to build the geology information data base. And, information carries out quality inspection on record geology in entering a data base. Improve the accuracy of mineral resources assessment. Study the area geology data by analysis, To ascertain the copper mineral ready-made an ore being beneficial to a key element of this region.By use space analyses function of GIS software, to extracted favorable evidence layer for prospecting, make use of the Arc-WofE module to carry out excellent selections on evidence thematic layer. Calculate weight value of every evidence layer and the post-probability value of every cell in study area. At last generates cell posterior probability picture,and analysis the result to divide a grade of the posterior probability picture.By using the method of Weights-of-Evidence to assessment of mineral resources of copper in East Tianshan mountain region,find out five copper ready-made an ore being beneficial to area,analysis forecast result discovering answer to geology reality thing basic. Provide direction further for area's turn to look for an ore, forecasting achievement is more penetrating. Have improved this area copper mineral deposit resource forecasting the efficiency working. Union the father research results,Discover that method getting fine forecast effect of assessment of mineral resources of copper in East Tianshan mountain region.
