摘　　要：罕达盖铁铜矿床是近几年内蒙古国土资源大调查工作中新发现的一个小型铁铜矿床。矿床产于石炭纪石英二长闪长岩与中奥陶统多宝山组地层外接触带的矽卡岩中,矿体的形态及空间分布受接触带控制,矿体的产状随着岩体与地层的接触带及矽卡岩总体产状的变化而改变,属典型的矽卡岩型铁铜多金属矿床。本文通过对区域地质、矿区地质、物化探异常特征及矿体的特征进行研究,总结了矿床地质特征及找矿标志,并对控矿因素和矿床成因进行了探讨,对今后矿区及其外围的找矿工作具有指导意义。The Handagai ore deposit is a small-size iron- copper deposit discovered during the landsurvey in Inner Mongolia.The iron- copper deposit originated from Carboniferous quartz monzodiorite and Middle Ordovician Duobaoshan Formation in the outer contact zone of skarn, form and spatial distribution of the ore bodies controlled by the contact zone, the occurrence of the ore bodies as the rock mass and the formation of the contact zone and overall attitude change with the change of the skarn, it is a typical skarn type iron and copper polymetallic deposit. By studying the regional geological, ore field stratum, geophysical-geochemical anomaly characteristics and ore characteristics, it has summarized geological characteristics and ore prospecting criteria of the deposit, and discussed ore-controlling factors and origin of ore deposit. It has guiding significance for the mining area and its peripheral prospecting in the future.
