Geochemical specific features of ores and ore minerals of two titanomagnetite deposits (Big Seiim and Kuranakh) and the associated Kalar gabbro-anorthosite massif are given. The first deposit is located in gabbroids, while the second one in anorthosites. Increased manganese, cobalt, scandium concentrations are typical of ilmenite, while vanadium, chrome, nickel contents are observed in magnetites. Ore minerals in the gabbroids and anorthosites differ in iron group element concentrations. This results from different settings of ore formation. The ores are complex (apatite-i1menite-titanomagnetite) at the Big Seiim deposit. Phosphorus is mainly concentrated in fluorine apatite. There is no correlation between titanium and phosphorus. The “clearing” of ore from admixture elements in the process of metamorphism improves their properties.
