    Review of geology, alteration and origin of iron oxide

    Highlights The iron oxide–apatite deposits in the Ningwu basin are magmatic–metasomatic origin. These deposits are similar to the Kiruna-type deposits in Scandinavia and elsewhere. They were formed in a rift or extensional environment. The mineralization is associated with alkaline magmatism. The time interval between magmatism and related mineralization is very short.
