Abstract
The Mitrashinci deposit in Eastern Macedonia represents a unique type of metamorphosed Fe–
Ti deposits. Fe–Ti oxide mineralization was identified in amphibolites from the metamorphic complex of the
Serbo–Macedonian massif, which comprise two different stratigraphic horizons striking NW–SE. At
Mitrashinci, Fe–Ti oxide mineralization is hosted by deeply buried amphibolites of the second stratigraphic
horizon. Two types of amphibolites were recognized, almost barren garnet–biotite and mineralized garnet–
cummingtonite. The mineralized zone (varying in thickness from 20 to 300 m) has been traced for 12 km
within amphibolite host rocks. Several lens like ore bodies hosted by garnet–cummingtonite amphibolites
striking NW–SE have been intersected by mining operations at Kobilski Rid, Gromadna, Leskovica, Dolga
Poljana, and Bliznakov Cukar. The contents of Fe and Ti vary greatly in the ores (13–23% and 4–9.1%,
respectively). The ore bodies consist mainly of Fe–Ti oxides, such as magnetite, titanomagnetite, ilmenite,
and hematite (martite), and minor pyrite, chalcopyrite, pyrrhotite, rutile, titanite, leucoxene, and goethite.
The major ore minerals (ilmenite, titanomagnetite, and magnetite with a minor sulfide phase) were formed
during the magmatic phase of ore deposition and were not considerably affected by subsequent polyphase
metamorphism.
