高地银多金属矿位于突泉林西华力西、燕山期铁（锡）、铜、铅、锌、银、铌（钽）成矿带内。矿区广泛发育晚侏罗世火山岩系，晚侏罗世—早白垩世中酸性岩浆侵入强烈，断裂构造较发育，化探异常重现性较好，视极化率异常与化探异常吻合。异常区已发现10条矿化蚀变带，均受断裂构造控制，并具有较好的银矿化显示。矿区具备了良好的成矿物质来源和活化、迁移及富集条件，岩浆热液型银多金属矿的找矿前景较好，应关注与大断裂派生的次级断裂及岩浆热液有关的银多金属矿床的找矿工作。%Gaodi silver polymetallic deposit is located in Tuquan Linxi metallogenic belt of iron (tin), copper, lead, zinc, silver and niobium (tantalum) in Variscan and Yanshan period. The upper Jurassic volcano sedimenta-ry rocks widely developed in this area. Intermediate acidic magma intrusived strongly in late Jurassic early Creta-ceous periods and faults developed well. Geochemical anomalies have good reproducibility, and the apparent polari-zation anomalies coincide with them. 10 mineralization and alteration zones with certain silver mineralization wre de-lineated in these abnormal areas, which controlled by faults. This Mining area has good ore forming material sources and conditions for ore forming material activation, migration and enrichment. It will be a good prospecting for hydrothermal silver polymetallic ore, and should focus on prospecting the silver polymetallic deposit which asso-ciates with Secondary faults derived from large faults and magmatic hydrothermal fluids.
