摘要
经透射电镜研究,在祁雨沟金矿床的冰长石中发现有自然铜超显微包体。作者认为这种超显微包体是在低fs_2、fo-2、富Cl的条件下形成,Cu是以CuCl-2^-络合物形式搬运。晶出的自然铜被正在结晶的冰长石捕获,使其封闭起来,未受到后来富fs_2流体的作用。
The ultramicro inclusions of native copper were discovered in adularia in the Qiyugou gold deposit, Henna Province. Its crystallization proceeded under low fs_2, fo_2 and abundant Cu conditions. Cu is considered to have heen transported in the form of CuCl_2. The crystallized native copper had been trapped by adularia under crystallization, and thus was not subjected to the influence of later fluids.
