%X The Platinum-group elements ( PGE) geochemistry of rocks and copper-nickel sulfide ores from Jianchaling deposit is systemically studied by ICP-MS testing method. The Cu/Pd ratio of serpentinite is lower than that of original mantle magma, indicating that magmatic liquation is weak, and the Au/Pd ratio of the serpentinite reflects the post-magmatic emplacement metamorphic hydrothermal minealization is also responsible for the formation of the copper-nickel sulfide deposit. The Pd/Ir ratio of ores changes in a small range, showing the ores belong to magma-type, although magmatic action is relatively weak in the ore field, but the magma ore-forming process play an important role in the formation of copper-nikel sulfide ores. The Platinum-group elements characteristic parameter for the sulfide nickel deposit have transition feature, which is corresponding to transition tectonic setting of the minerlization, special magma composition, and complicated metallogenesis. The substances of the crustal source have contaminated during ore-forming process, the content of PGE for the rocks and ores are low. On the whole, this can be ascribed to weak magmatic liquation and undeveloped PGE mineralization.
