摘　　要：为了实现金川岩浆型铜镍硫化物矿床深边部找矿工作的有力突破,对其两种主要成矿理论进行系统对比研究,发现对金川岩浆型铜镍硫化物矿床现今矿体深部就位位置的认识存在差异性。在深部熔离-贯入成矿理论中以归纳含矿岩体的推覆构造机理为主,以复原该含矿岩体异地就位位置的空间形态;在岩浆通道系统成矿理论中以现有矿体空间展布实际产状为主,以此构建整体岩浆上升通道及成矿有利空间,以研究现矿体深部原地就位位置的空间形态。In order to realize the progress of deep edge prospecting in Jinchuan magmatic copper-nickel sulfide deposit,the two main metallogenic theories were systematically compared and studied.It is found that there are differences in understanding the current location of ore bodies in the Jinchuan copper-nickel sulfide deposit.In the theory of sulfide segregation and injection,the main focus is on studying the nappe structure mechanism of ore-bearing rock masses,in order to restore the spatial morphology of the ore-bearing rock masses in different locations;In the theory of magma conduit metallogenic system,the actual occurrence of existing ore body spatial distribution is mainly used to construct the overall magma ascending channel and favorable mineralization space,in order to study the spatial morphology of the deep in-place position of the existing ore body.
