库尔斯克磁异常区(下简称库区)的富铁矿与前寒武铁硅质建造的风化壳的成因关系,未曾予以专门的探讨。这是由于矿体的地质构造和产状特征显然是同风化壳密切有关的缘故。如该区的矿体大多数成钟状,产在含铁石英岩风化剖面的上部,形成了一个厚度不等的带。 The genetic relationship between the iron-rich ore in the Kursk magnetic anomaly (hereinafter referred to as the reservoir area) and the pre-Cambrian siliceous weathering crust has not been discussed specifically. This is due to the fact that the geological structure and occurrence characteristics of the ore body are apparently closely related to weathering crusts. For example, most of the ore bodies in the area are bell-shaped, and are formed in the upper part of the weathering profile of iron-bearing quartzites, forming a zone of varying thickness.
