新疆巴仑台铁铜矿赋存于华力西期中酸性侵入岩与碳酸盐的接触带上，矿体形态以似层状、透镜状为主。围岩蚀变主要有矽卡岩化、绿泥石化、绿帘石化、硅化。矿石矿物以磁铁矿、黄铁矿、黄铜矿为主，脉石矿物中有典型的矽卡岩矿物透辉石、石榴子石。矿床成因类型为矽卡岩型。该矿床的成矿作用主要为热液交代作用，其过程分为矽卡岩期、石英硫化物期和表生期3个成矿时期。
新疆巴崙檯鐵銅礦賦存于華力西期中痠性侵入巖與碳痠鹽的接觸帶上，礦體形態以似層狀、透鏡狀為主。圍巖蝕變主要有矽卡巖化、綠泥石化、綠簾石化、硅化。礦石礦物以磁鐵礦、黃鐵礦、黃銅礦為主，脈石礦物中有典型的矽卡巖礦物透輝石、石榴子石。礦床成因類型為矽卡巖型。該礦床的成礦作用主要為熱液交代作用，其過程分為矽卡巖期、石英硫化物期和錶生期3箇成礦時期。

Baluntai iron-copper deposit of Xinjiang hosts in the contact belt of Variscan intermediate-acidic intrusive rocks and carbonate rocks, ore body form is given priority to with layered, lenticular. Alterations of wall rocks are mainly skarnization, chloritization, epidotization and silliifcication. Ore minerals are mainly magnetite pyrite and chalcopyrite and gangue minerals consist of typical skarn type minerals such as diopside and garnet. The genetic type of this deposit is of skarn type and it's mineralization is mainly hydrothermal replacement with three ore-forming stages:skarn stage quartz-sulifde stage and supergene stage.
