Manifestations of regional uglerodizatsii in the etamorphiccomplex are Riphean age of the northern part of Khankaisky terrane. Using various methods of physicochemical analysis reveals elevated concentrations (10-4-10-6 wt.%) of gold and platinum group lements (PGE) in all petrographic varieties of rocks of this complex. According to x-ray fluorescence analysis of described a wide range of geochemically different types of rare and traceelements: Ti, V, Ni, Cr, Pt, Pd, Re, Rh,Os, Ir, Cu, Hg and Au, Ag, Ta, Nb, Sr, Rb, Zr, La, W, Sn, Pb, Zn has been distinguished. In this connection, the development of technique of extracting of gold and platinum group metals from high-carbon rock off the Khankaisky area, is very important.
