| 摘 要： | 对老和尚帽地区区域地质背景、控矿因素、遥感及物化探特征的综合分析后认为,矿源层、NWW向次级正断层、燕山期岩浆岩、重磁场歧变带、遥感环带状影像区及Ag衬值异常强度和异常面积的大小都是该区银多金属矿床的很重要的找矿信息。通过分析,确立了综合找矿标志,并采用矿床模型法,依据资源总量进行找矿靶区的定位预测。圈定了七处可供进一步普查的银多金属找矿靶区。

| Abstract: | It is considered that source layer,NWW trending divergent zones of gravity-magnetic field, remote sensing ring image zone and the strength and area of Ag contrast anomaly are all important information for prospecting, based on the comprehensive analysis on regional geological background, ore controlling factors, remote sensing and geophysical-geochemical exploration. A comprehensive information model for prospecting was established by way of analysis and localization prediction of the prospecting target was carried out according to total reserves by use of deposit modeling. 7 silver polymetallic ore prospecting targets were outlined for further reconnaissance survey. |
