摘要
大湖塘矿田位于江西北部九岭钨多金属成矿带中部,面积约200 km^2。本文以地质、物探、化探、遥感等地质找矿标志作为预测因子,运用综合找矿信息量、特征分析等数理统计方法进行成矿有利信息量、特征变量计算,认为石英脉(带)及燕山花岗岩是找矿的重要标志。利用MAPGIS平台,对网格单元找矿总信息量及关联度等值线进行了二次圈连。共圈定找矿可行地段2个,通过野外地质调查及钻孔验证,取得较好地质找矿效果,说明该预测方法对找矿具有一定的参考和指导意义。
With a size of 200-odd square kilometers, Dahutang ore field is situated in the middle ：section of Jiuling tungsten polymetallic metallogenic belt. Using the various geological prospecting signs,~ including geology, geophysical prospecting, geochemical exploration and remote sensing, as prediction factors, we suggest that quartz veins （belt） and Yanshan granite are important signs of prospecting by applying mathematical statistics. MAPGIS platform is utilized to perform the secondary circle on the grid unit prospecting information and correlation degree contour. Two feasible prospecting the forecasting method has certain plot was determined. Field geological survey and drilling verification proved that reference and guidance significance to tungsten prospecting.
