Abstract:The line-6 copper(PGE)-rich orebody of Jinchuan Cu-Ni sulphide deposit is considered as the product of postal magmatic hydrothermal superimposed mineralization by some researchers. From study, the orebody is controlled by fault structure in space and it is same with adjacent magma liquation 1# orebody in aspects as ore fabric, mineral composition and sulfur isotopic composition. The orebody shows characteristics of magmatic mineralization. In element geochemistry, prospecting line 6 copper(PGE)-rich orebody Cu, Ni, Pt and Pd contents and Cu/Ni value appears obviously higher than 1# main orebody, whileas, Os, Ir, Rh and Ru contents appears obviously lower than the latter. Comparatively, the former has rich LREE and differentiation of light and heavey lanthanon is higher than the latter. Based on Metal Elements distribution rules and lanthanon characteristics during the period of sulfide crystallization differentiation, this paper demonstrated prospecting line 6 copper-rich (PGE) orebody as magma condiut type orebody, it is the products of the late stage crystallization of liquid magmatic sulfide. In the Midwest of the mining area, Cu, Ni, Pt, Pd and Au contents are high. In the zone of Os, Ir, Rh and Ru low contents where is the advantage location to prospect for magma condiut type orebody.
