Abstract:The paragenesis phenomenon between V—Ti magnetite deposits and sulfide deposits has not yet been found all over the world. Although it was deemed a PGE—Cr enriched layer in the bottom of the ore body at Hongge deposit, the consequence by analyzing lots of drilling samples is not really as the prior viewpoint in Hongge mining area which is in the west of Sichuan province. However, we find the existence of a large amount of massive sulfide deposits ore which can form Fe—Co—Ni paragenetic orebody after piercing into iron orebody in Baicao mining area in at Hongge deposits. The major compositioningredients of massive sulfide ores are pyrrhotite (94%), pentlandite and chalcopyrite, and a few ingredients of augite, sahlite, bronzite, hornblende, phlogopite, magnetite, ilmenite, and andesine, etc. The tenoramount of Ni is 0.72%~0.90%, while the tenoramount of Co is about 0.10%. These two elements mainly exist in the pyrrhotite. The experimental analysis of Platinum Group Elements indicates that the Cu/Pd ratio is between 12908 and 15109 in massive sulfides, while it is about 24520 in iron ore with 3% penetrated sulfide. These Cu/Pd ratios are much higher than primitive mantle source value which implies the tiny amounts of sulfide residue in magmatic source. Meanwhile, sulfide phase separations have of the sulfide occurred before the iron ore form. In Hongge area, Pd/Ir ratios of samples ranging from 2.8 to 30, mainly concentrated between 8 and 14, suggestshow it might experience a strong magmatic crystallization. An obvious fractionation phenomenon of Platinum Group Elements in Hongge deposit suggests that sulfide deposit and iron may accumulate simultaneously in fluid. It is difficult to explain the obvious differences of PGE contents by the same magma chamber among different mining areas which can be the product of magmatic evolutions in multistage magma chambers. It may imply that there is awill be a subsurface magma chamber where exists Ni—Cu—PGE deposits and Fe—Ti—V deposits in deepth.
