Iron deposits in the precambrian iron-ore formations of the Aldan-Stanovoy shield

The article provides brief information about the distribution of the iron ore formation on the continents, with which the largest iron ore deposits are associated. It is indicated that a signifi cant component of the ferruginous quartzites of many deposits of the world, as deposits of rich iron ores of other formations formed due to them, are noble metals, which act one of the largest unconventional sources of associated gold and platinum mining in the 21st century. The common features of iron deposits of iron ore formation on diff erent continents are outlined. Information is provided on the identifi ed iron ore deposits of this formation in diff erent countries and on the territory of Russia, in particular, on the Aldan-Stanovoy shield, where they are developed in its iron ore regions, identifi ed, for the most part, in the Precambrian strata along deposits of iron ore rocks formations. As examples, geological descriptions of several of the most signifi cant deposits of ferruginous quartzites discovered on the territory of the Sutam block, which form the Sutam iron ore region of ASCH, are given. A brief description of the mineral composition of the ores of these iron deposits is given. The deposits of this region, according to the author, when they are involved in iron mining, will play an importent role in the economic development of South Yakutia.
