【摘要】 为了提高找矿决策部署的科学性,优先要解决找矿远景区的优选问题。文章以江西找矿远景区优选研究为例,从全省矿产资源潜力评价成果数据入手,对预测资源量进行可信度分析,并补充近期找矿效果,然后通过MapGIS空间分析平台,系统提取全省18个矿种的"查明资源量、预测资源量及其可信度、最小预测区面积、近期找矿效果"等综合因素,定量分析全省成矿强度与矿化规模,勾绘出江西省综合成矿强度等值线,并按矿化规模从大至小排序,实现找矿远景区优选。研究结果表明,赋春—塔前地区为江西省首选的找矿远景区,其综合成矿强度值为108 573 t/km~2,矿化规模达36个大型矿床数,主攻矿种钨、铜。更多还原

【Abstract】 In order to makeing prospecting decision more scientific,the optimization problem of prospecting area is urgent.Taking preferably prospecting area in Jiangxi as an example,starting from the mineral resources potential evaluation data,forecasting analysis on the amount of resource reliability,adding the recent prospecting effect,and then through the MapGIS spatial analysis platform,consider the identify resources,predicted resources and its confidence values,minimum prediction area,the prospecting effect and other factors,quantitative analysis of the mineralization intensity and mineralization scale,draw the contour lines of comprehensive mineralization intensity,according to the mineralization scale from large to small order,realize the prospecting area optimization.Research shows that Fuchun-Taqing area is the first choice of prospecting area in Jiangxi,its comprehensive mineralization intensity value is 108 573 t/km2,mineralization scale is 36 large scale deposit,the main minerals are tungsten,copper.更多还原
