摘要
在总结宝丰地区已有铝土矿成矿规律的基础上,以综合信息矿产评价理论为指导,利用GIS平台提取了地质、地球物理、地球化学、遥感等多元地质找矿信息,采用证据权重法进行了多元找矿信息综合,对有利成矿区进行了圈定,共圈定了4个铝土矿资源远景区。预测结果显示,在宝丰及邻区有两条北东—南西向和两条北西—南东向的有利成矿区带,已知的86%的矿床集中于此地,表明该方法具有良好的预测效果。
Based on full understanding of characteristics of geological setting and mineralization regulation of bauxite deposits in Baofeng area, and directed by the comprehensive theory of geology, geophysics, geoehemistIy and remote sensing information extracted by GIS, a multi - prospecting information integrated by weight evidence method is proposed. And four favorable mineralization areas were predicted with the method above. The prediction results show that there are two NE - SW and two NW - SE favorable metallogenie areas, where 86% of the bauxite deposits in Baofeng area occur. This demonstrated that the method had good prediction effects.
