基于熵权法的新疆阿尔泰成矿区金矿床定位预测研究
Research on the Location Prediction of Gold Deposit in Altay of Xinjiang With the Entropy-Weighted Method
摘要
Abstract
This paper combines entropy and gray correlation degrees to study the relationship between geological variables and ore units to locate ore targets. The 87 key geological variables are obtained from geological, geochemical and geophysical data. Based on the theories and methods of metallogenic prognosis by using synthetic information, the study area (in Altay, Xinjiang) is divided to 16 gold deposit concentrated areas and 14 gold anomaly-concentrated areas. Then, this article introduces entropy-weighted method to deal with qualitative and quantitative variables, respectively, and then use the gray correlation to describe the similarities between the deposit units. The results show that gravitational gradient, aeromagnetic, and catchment are effective indicators to look for gold mines and unit number 6, 22, 18, 19 and so on contain a large gold deposit, respectively, which was confirmed by other means. This shows that the method can be effectively applied to delineate and assess ore-finding targets.关键词
