从所周知,元古代是多种金属矿产的重要成矿时代.已知国外元古界地层中形成的铁、铜、铅、锌多金属矿产资源,均占有重要地位,其中层控金属矿床更为重要.内蒙西部元古界地层分布区,是我国铁、稀土、铌和铜、铅、锌、硫铁矿等矿产重要成矿区之一. It is well-known that the Proterozoic is an important metallogenic epoch of various metallogenic minerals.It is known that the iron, copper, lead and zinc polymetallic mineral resources formed in the Proterozoic strata in foreign countries all play an important role, among which stratabound metallogenic deposits are even more Is important.The distribution of Proterozoic strata in western Inner Mongolia is one of the important mineralized regions of iron, rare earth, niobium and copper, lead, zinc and pyrite in China.
