摘　　要：作者对研究区做了多次踏勘与详细检查,对塔什库尔干县一带铁多金属矿床的成矿地质特征获得了一些新的认识。区内已发现的34处铁多金属矿产地多为中-小型规模,矿化类型以沉积变质型、矽卡岩型及岩浆热液脉型为主。通过对典型矿床的对比研究,并结合航磁异常解释和化探异常分析,认为研究区内各类型矿产分布具一定的规律性,且成矿范围广、矿化集中、品位较富。表明研究区成矿地质背景优越,具有较好的找矿前景和资源潜力。Taxkorgan area is one of the important mineral prospects in Southern Xinjiang. As the national geological survey and geological prospecting works proceed, a lot of geological prospecting achievements have been obtained in this area. Geochemical and aeromagnetic survey indicates this area is a promising prospecting target. 34 iron polymetallic deposits have been discovered during the preliminary investigation and detailed investigation, most of which are small to medium sized metamorphosed sedimentary type （Tahaxi iron deposit, Zankan iron deposit, Laobing iron deposit, Tahaman iron deposit）, post magmatic superposition filled vein skarn type （Kangdaer Zn-bearing magnetite, Waqia copper lead and zinc deposit） and magmatic hydrothermal vein type （Kekeshenlaoke lead-zinc deposit, Dabudaer beryl） deposits. Comparative researches show that this area is a favorable prospecting area for diverse mineralization of rich ores.
