变质岩铁矿是世界上最重要的铁矿类型,其储量在我国铁矿总储量中占50%以上,在国外铁矿总储量中占60%以上.铁矿资源丰富、矿石产量大的国家,都拥有规模大的变质岩铁矿,特别是大型变质岩富矿.目前,我国除个别省(区)外,均已发现有变质岩铁矿;而且规模大的变质岩铁矿较多,并有与热液作用有关的大型富矿.因此,加强这种类型铁矿的普查与勘探,开展其区域 Metamorphic iron ore is the most important type of iron ore in the world, its reserves account for more than 50% of China’s total iron ore reserves and more than 60% of the total iron ore reserves in foreign countries. Iron ore rich in resources, large ore countries , All have large-scale metamorphic rock iron ore, especially large-scale metamorphic rock rich ore.At present, except for some provinces (autonomous regions) in China, metamorphosed rock iron ore has been found, and the large-scale metamorphic rock iron ore is more There are large-scale rich ore related to the hydrothermal effect.Therefore, to strengthen the census and exploration of this type of iron ore, to carry out its region
