基于GIS和证据权重法在豫西南东山洼地区成矿预测中的应用

Based on GIS and the weights of evidence method in YuXiNa east in its forlornness up the application of the metallogenic prediction

通过对豫西南东山洼地区成矿地质条件和典型矿床的研究,综合地、物、化、遥等多元地质找矿信息,建立了东山洼地区银多金属矿综合信息找矿模型。在MORPAS平台中利用证据权重法对东山洼地区进行了成矿预测,共圈出2个Ⅰ级找矿靶区和4个Ⅱ级找矿靶区,为该区进一步找矿指明了方向。

By YuXiNa east in its forlornness up the metallogenic geological conditions and the typical study, synthetically and physical, chemical, remote multivariate geological prospecting information, such as set up in its forlornness up east silver polymetallic ore comprehensive information prospecting model. In the MORPAS platform using evidence weight method was carried out on the east in its forlornness up the metallogenic prediction, a total circle 2 grade I prospecting target areas and four class II prospecting target areas, pointed out the direction of the further prospecting in the region.
