On the prospects of identifying magmatoge ne-hydrothermal iron-ore deposits in the Ukrainian Shield

© À.A. Yushin, 2015

According to the analysis of literary materials and author's own observations in different regions of the world, a specific set of iron-ore and related deposits, won the international title of «hydrothermal iron-oxide-gold-copper deposits» (IOCG — Hydrothermal Iron Oxide Copper-Gold Deposits) has been described here. The most important feature of IOCG-type deposits are large masses of iron, often forming clusters of magnetite-rich (at least — hematite) ores of magmatogene and magmatogene- hydrothermal genesis. It is shown that the type of IOCG deposit can be discovered within the suture zones of the Ukrainian Shield on the example of the installation within the Krivoy Rog-Kremenchug structural and metallogenic zone of paragenetic association of hydrothermalmetasomatic mineralization of gold-polymetallic manifestations and certain types of rich iron-ore. Geophysical surveys must play the leading role.

Key words: deposits, magmatic, iron oxides, copper, gold, structures, the Ukrainian Shield.
