The Role of Iron Ores of the Sutamsky District in the Economic Development of the East of South Yakutia and Their Characteristics

Abstract

In the 80th years of the last century the works on systematization and generalization of the geological materials with a view to prospects for iron of the Aldan iron ore province were completed. As a result of these works, in addition to well-known iron ore deposits of the Chara-Tokkinsky and Central Aldan groups lying in the Upper Archean complexes of the region, a number of promising manifestations of ferruginous quartzites in the Sutam iron ore region associated with the deep metamorphosed oldest Early Archean formations of the Aldan Shield were established. This assessment of the Sutam district allows to put it on the third place in the Aldan Province with preliminary reserves of 3.5-4.0 billion tons of magnetite quartzites, suitable as a raw material for powder metallurgy, which determines a practical interest in the development of the deposits.
