【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。
[Abstract]:The Dahutang Orefield is located in the middle of Jiuling tungsten polymetallic metallogenic belt in northern Jiangxi, with an area of about 200 km / m ~ 2. In this paper, geological prospecting markers such as geology, geophysical exploration, geochemical exploration and remote sensing are used as prediction factors, and mathematical statistical methods, such as comprehensive prospecting information and characteristic analysis, are used to calculate the favorable information and characteristic variables. Quartz vein (belt) and Yanshanian granite are important indicators for prospecting. Based on the MAPGIS platform, the secondary circle connection of the total information and the correlation contour of the grid unit is carried out. Through field geological investigation and borehole verification, a better geological prospecting effect has been obtained, which shows that the prediction method has certain reference and guiding significance for prospecting.
