采用镍锍试金预处理中子活化分析方法，测定了冷水箐铜镍硫化物矿床的矿石和含矿围岩的铂族元素含量，探讨了岩浆演化和熔离作用过程中铂族元素的地球化学行为和贵金属配分型式。结果表明，冷水箐矿床的铂族元素配分型式与玄武岩浆有关的铜镍硫化物矿床相似，而明显不同于与科马提岩浆有关的铜镍硫化物矿床。认为冷水箐岩体镁铁－超镁铁岩的原始岩浆为玄武岩浆。
Nickel-matte gold pre-treatment neutron activation analysis was used to determine the content of the platinum group elements in the ore and the ore-bearing rocks in the Lengshuiju copper-nickel-sulfide deposit. The effects of magma evolution and melting on the Earth Chemical behavior and precious metal allocation type. The results show that the distribution pattern of the platinum group elements in the Lengshuijiao deposit is similar to that of basaltic magma copper-nickel sulphide deposits, but distinctly different from the Cu-Ni sulphide deposits related to the Komati magmatism. It is considered that the primitive magma of mafic-mafic-ultramafic rocks in cold-water 为 is basaltic magma.
