摘要: 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.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及贵金属矿是经深源熔离和脉动式多次成矿作用形成的.Abstract: Kalatongke sulphide copper and nickle deposit can be divided into three genetic types in intrusive sequence-liquation,injection and hydrothermal superposition types.The last two have a close relation to precious metal mineralization,especially the hydrothermal mineralization.For example, the precious metal(Au,Ag,Pt and Pd)is mainly enriched in high copper massive ore body that separated from the hydrothermal mineralized fluid.The deep melt time of ore-bearing magma in magma house is opposite to the intrusive sequence of each genetic type of ore body. Cu,Ni and precious metal ore body is formed through deep-liquation and mutiple pulsative mineralization.
