Trace element composition (Zn, Pb, In, Cd, Ag, As, Sb, Se, Te, Mo, Sn, Ru, Rh, Os, Ir, and Pt) of sulfide inclusions in garnets was studied with a proton microprobe HIAF. The PGE contents of sulfides are 15-300 chondrite values. This is several times lower than that of sulfide globules from olivines and diamonds. The sulfides have similar chondrite-normalized PGE patterns with a clearly pronounced Ru minimum which is not typical of sulfides from diamonds and olivines.
