Recentl,a mantele mineral assemblage consisting ofdiamond,coesite, Si-rutile,native elements,alloys,oxides,sulfides and sulfo-arsenides was found in chromitite of Luoobusa ophiolite in the Yarlung Zangboophiolite zone,Tibet.The sulfides and sulfo-arsenides with specific compositions occur as inclusions inbasemetal and PGE alloys.Based onchemical analyses,the authors have found that the elements comprising the minerals are mainly S,Ar,Te,Fe,Ni,Co,Cu,Pt,Pd,Os,Ir,Mn and Ti.Thirty different sulfide and sulf-arsenides mineral species in chromitite of the Luobusa podiform chromitite were identified,which include named and unnamed minerals: FeS,NiS,(Ni,Fe)S,Fe3S2,Ni3S2,(Ru,Os,Ir)s2,RuS2,Rh7As3,Rh5Ni(Cu)As4,Pd4Rh3As3,Pd8As2,Pd3Te3As,Pd7Te3,RuAs,PtAs2,Ni4Rh3As3,Rh(As,S)2,RuS2, Rh7As3,, Rh5Ni(Cu)As4, Ed4Rh3As3, Pd8As2, Pd3Te3As, Pd7Te3, AuAs, PtAs2, Ni4Rh3As3, Rh(As, S)2, (rh, Ir)(As, S)2, Ir(As, S)2, MnS, Ti7S3, Ti7N3, Rh3.5Se3.5cuS2, RhS, Ir2S3, (Ir, Cu)2S3, (co, Ni, fe)2(As, s)3, (Ir, Pt)(As, S)2, Ru3(As, S)7 and (BM)x(PGE)yS10-(x+y. As mineral crystals are too small(<25 um), and X-Ray analytical data remain very insufficient for unnamed minerals, much research work remains to be done in future.
