Abstract
It is considered that source layer,NWW trending secondary normal fault,Yanshanian magmatites,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.
