西北地区幅员广大,地质条件优越,沉积了各个时代和不同岩性的地层,地质构造复杂,岩浆活动频繁,火山岩及各个时期的酸性、基性及超基性侵入岩广泛发育,这些给成矿创造了有利条件,也是控矿的主要因素。解放后,在毛主席和党中央的英明领导下,进行了大量的区域地质调查和矿产普查勘探,发现了许多矿点、矿化点,探明了一批铁矿床,积累了丰富的地质资料。遵照毛主席关于“在生产斗争和科学实验范围内,人类总是不断发展 The vast area of ​​the northwestern region, superior geological conditions, deposition of various epochs and lithology of different strata, geological structure is complicated, magmatic activity is frequent, volcanic rocks and various periods of acid, basic and ultrabasic intrusive rocks widely developed, which give the mineralization Created favorable conditions, but also the main factor of ore control. After the liberation, under the wise leadership of Chairman Mao and the Party Central Committee, a large number of regional geological surveys and mineral prospecting surveys were conducted, many ore points and mineralization sites were discovered, a number of iron ore deposits were discovered, and abundant geology was accumulated data. Following Chairman Mao’s statement that "mankind always develops continuously in the context of the struggle for production and scientific experimentation
