n the rocks of Bobruisk ring structures (Republic of Belarus) distributed native and intermetallic compounds, alloys containing C, Si, Fe, Cr, Cu, Pb, Sn, Zn, Mo, Al, Ag, Ni, Co, W, B. V. the Most common are moissanite, graphite and native iron (0-11% Cr), chromferide (12-13% Cr), and alloys of Fe-Cr (14-75% Cr). To areas of their development are confined polymineral aggregates folded iiitm, magnetite, maghemite, hematite, escalator in the form collaborating units. Fixed transitions from native and intermetallic phases. The formation of these associations in rocks of different composition and age reflects the deep mantle vosstanovitelnuyu the nature of the fluids caused the mineral formation.
