Реферат:	eng: Experimental studies of the Fe-0-(Mg, Ca)CO3-S system were carried out during 18-20 h at 6.3 GPa, 900-1400 degrees C. It is shown that the major processes resulting in the formation of free carbon include reduction of carbonates upon redox interaction with Fe-0 (or Fe3C), extraction of carbon from iron carbide upon interaction with a sulfur melt/fluid, and reduction of the carbonate melt by Fe-S and Fe. S-C melts. Reconstruction of the processes of graphite formation indicates that carbonates and iron carbide may be potential sources of carbon under the conditions of subduction, and participation of the sulfur melt/fluid may result in the formation of mantle sulfides.
