Multiple Information Metallogenic Prediction Based on the Analytic Hierarchy Process:A Case Study of the Lhozhag Area in Tibet
摘要
Abstract
This paper presents multiple information metallogenic prediction for the Lhozhag area in Tibet where a project of basic geological and miner-al surveys is underway. The SPOT-6 and ETM+ data are selected for geologic interpretation of remote sensing imagery. From the ASTER data,the re-mote sensing alteration anomalies are extracted. A 1:50000 drainage sediment survey allows us to obtain geochemical anomalies. Combined with existing geological data and other information,this work determines the influence factors of the regional mineralization,which are then analyzed by the analytic hi-erarchy process(AHP), and the weight values of each factor are calculated. Using the GIS platform, all weight factors are analyzed by stack, and six prospect areas of mineralization are delineated. In light of this prediction,copper and lead mineralization sites are found through field investigations,pro-viding technical support to geological and mineral resource surveys in this region.关键词
