铁矿床是地壳演变中发生发展的,在时间上与地壳发展的一定阶段相联系,空间上与一定的大地构造相依存。地壳演化的规律性,决定了铁矿空间和时间分布上的规律性;在地壳演化过程中,构造岩浆活动的差异,原始地幔的分异和演化以及海陆变迁和气候变化等因素,又决定铁矿类型的多样化。在多种多样矿床之间,即互相联系又互相区别,故可以进行分类。鉴于以往分类多从成因类型考虑的,常忽略地质发展中矿床生成之间的联系,孤立地
The development of the iron deposit occurred during the evolution of the crust. It is associated with a certain stage of crustal development in time and is space-dependent with certain tectonics. The regularity of the evolution of the crust determines the regularity of the spatial and temporal distribution of the iron ore. During the evolution of the crust, differences in tectonic magmatism, differentiation and evolution of the original mantle, changes in land and sea, and climate change also determine the iron Diversification of mine types. In a variety of deposits, that is, mutual contact but also different from each other, it can be classified. In view of the past classification more from the genetic type considered, often neglected geological formation in the relationship between the formation of deposits, in isolation
