Kremenchug Magnetic Anomaly

Kremenchug Magnetic Anomaly


a large iron-ore region in the Ukrainian SSR; a continuation of the Krivoi Rog “Iron Ore Basin to the north (the northern part of the Krivoi Rog-Kremenchug iron ore belt, about 45 km) across the Dnieper (Poltava Oblast, Ukrainian SSR). The anomaly is composed of a Precambrian iron-ore formation similar to the Krivoi Rog formation.

There are four known deposits in the Kremenchug Magnetic Anomaly: the Gorishni-Plavni, Lavrikovka, and Eristovka deposits are ferruginous quartzites, primarily of magnetite com-position, with iron contents of 34.8, 35.3, and 34.7 percent, respectively, and total reserves to a depth of 300 m in categories A + B + C1 of 1.22 billion tons; the Galeshchino (Kremenchug) deposit contains rich ores, primarily martite and martitehematite, partially carbonatized, with an average iron content of 58.2 percent, among oxidized ferruginous quartzites. The rich ores form small stratified, lenticular, and irregularly shaped bodies within the ferruginous quartzites, which were subjected to ancient weathering. The bodies of rich ores are traced down to 600–1,000 m on the dip. Reserves of rich ores down to a depth of 1,000 m in categories B + Ci are 167.1 million tons.

Exploration is under way at the new Belany deposit of ferruginous quartzites down to a depth of 300 m and at the Gorishni-Plavni deposit in the range of depths from 300 to 500 m.
