当前世界各国对矿产资源的需求与日俱增,而易识别矿越来越少,找矿难度越来越大(张磊,2009;毛先成等,2010)。如何快速有效地处理和利用与成矿有关的信息进行成矿预测,是当今地矿行业探讨的热点问题(张再天等,2012;郭栋,2012)。在成矿预测时,GIS以其强大的空间信息管理和分析功能,受到广大地质专家的青睐(矫东风等,2003;刘艳宾等,2012;Hosseinali
At present, the demand of all countries in the world for mineral resources is increasing day by day, while fewer and fewer identifiable mines are more and more difficult to find. (Zhang Lei, 2009; Mao Xiancheng et al., 2010). How to quickly and effectively process and use metallogenic information for metallogenic prediction is a hot topic in the field of geology and mineral resources (Zhang et al., 2012; Guo Dong, 2012). GIS is favored by a large number of geologists with its powerful spatial information management and analysis functions during ore-forming prediction (Jiao Dongfeng et al., 2003; Liu Yubin et al., 2012; Hosseinali
