| 摘 要： | 通过总结桂西北地区超微粒型金矿地质特征及成矿地质条件，为利用DPIS软件进行该区综合信息成矿预测提供了理论支撑。运用DPIS软件在桂西北金矿区提取对成矿有利的地质信息，并筛选地层、构造、化探异常和金属矿产等有用的找矿指示标志，进行信息量法统计预测，从而自动生成信息量色块图和信息量等值线图。基于信息量法统计结果，圈定出3处A级找矿预测区、2处B级找矿预测区和3处C级找矿预测区，简述了各找矿预测区的地质特征及找矿方向，为今后在桂西北地区寻找超微粒浸染型金矿指明了方向。

| Abstract: | Summarization about the geological characteristics and metallogenic geological conditions of the supermicrograin-type gold deposit in northwest of Guangxi provided the theoretical support for using DPIS software for comprehensive information metallogenic prediction in the area.The informative color chart and the informative isogram would be generated by using DPIS software to extract mineralization favorable geological information, screening useful prospecting indicator in stratigraphy,structure,geochemical anomalies and metal ores,and statistical forecasted for the amount of information in northwest Guangxi gold deposit.Based on the statistical results of the amount of information,three A grade ore prospecting area,two B grade ore prospecting area and three C- class ore prospecting areas are delineated.The authors outlined the geological characteristics and the prospecting direction for the future in every ore prospecting areas,and specified the direction for looking for the supermicrograin-type gold deposit in northwest Guangxi in the future. |
