摘要
The study of No.58 ore body is notonly very important forunderstanding the formation and distribution of the Cu-Ni sulfide ore bodies at Jinchuan but also significant for further exploration.Studies indicate that the geology and siderophile and chalcophile element geochemistry of No.58 ore body are different from those of No. 24,No.1 and No.2 ore bodies.The NNE-striking elongate No.58 ore body wasemplaced in the hanging wall of SegmentⅢand dips northwestward.Compared with other major ore bodies of the Jinchuan deposit,No.58 ore body has higher Cu,Ni and PGE content and its sulfide was produced by secondary sulfide segregation picritic magma slightly depleted in PGE,with the sulfide experiencing fractional crystallization in various degrees.
