摘要
笔者通过对新疆喀拉通克一号铜镍矿床的深入研究，得出了一些新的认识，即该矿床按侵位顺序可划分为岩浆熔离型、深熔贯入型和热液叠加型等成矿作用，其中后二者与贵金属的富集及成矿关系最为密切，尤其是热液作用最明显，例如：通过分析研究发现，贵金属Au、Ag、Pt、Pd主要在热液成矿流体分异形成的高铜块状矿体中富集；含矿岩浆在岩浆房中深熔的时间与各成因类型矿体侵位是反序的；Cu、Ni及贵金属成矿是经深源熔离和脉动式多次成矿作用而形成的．
This paper presents a thorough study on the Kalatongke sulphide copper and nickle ore deposit, the auther discovers that the deposit can be divided into three genetic types in instrusive sequence-liquation injected and hydrothermal superposition of which the last two have an important bearing on precious metal minerlization, and the hydrothermal mineralization is particularly important. It is also found that the precious metals (Au、Ag、Pt、Pd) are rich in high copper massive are body separated from the hydrothermal mineralized fluid; The deep-melt time of containing ore magma in magma house is opposite to the instrusive sequence of each genetic type of ore body; Cu、Ni and precious metal ore body is formed through deep-liquation and many-time pulsative mineralization.
