摘　　要：铁板井镍矿床赋存于辉橄岩体中,辉橄岩体具有全岩矿化的特点,岩体及镍矿体的形成经历了三种不同的成矿过程:首先是岩浆深源液态重力分异作用,而后发生岩浆深源熔离-贯入(成岩、成矿)作用,形成岩体和镍矿体,最后在岩浆期后热液作用的叠加下完成整个成矿过程。该矿床是典型的主要由岩浆熔离作用形成的岩浆矿床。In Tiebanjing area,nickel ore deposit which are wholly mineralized saves in the Pyroxene-Pendotite body. This paper describes three kinds of different mineralizing processes of the formation of the rock body and nickel ore body： the gravity separation process of deep liquid state magma, the process of deep magma melting away and penetrating, the formation of rock body and nickel ore body. Based on the analyses of the three kinds of different mineralizing processes, the author concludes that, from the result of postmagmatic hydrothermal superimposition process, the whole mineralization course is a process of typical magma ore deposit formation due to the process of magma melting away.
