基于GIS的冈底斯东段铜多金属矿多元信息成矿预测与潜力评价
Mineralization Prediction and Potential Evaluation Based on GIS and Multi-Source Information for Copper Polymetallic Deposits in the Eastern Gangdise Belt,Tibet
摘要
Abstract
Based on a complete collection and analysis of geological,ore deposits,remote sensing data, and geophysical and geochemical data of east-em Gangdise in Tibet about 200,000km2 , we investigated the geologic conditions and metallogenic rules and established a porphyry copper deposit metal-logenic model for this area. And then the indexes of metallogenic prognosis are summarized. Using the characteristic analysis method of mineral resource assessment system( MRAS) based on the geographic information system ( GIS), the metallogenic prospect has been predicted for porphyry copper poly-metallic deposits. Following that, the copper reserves were estimated by the quantification theory type I method. The result of metallogenic prognosis shows that the delimitaed area of metallogenic prognosis includes mostly known large and medium-sized copper deposits and is in accordance well with the geological analysis. The result of copper reserves estimated shows that there still exists a great potential of porphyry copper deposits in the eastern section of Gangdise.关键词
