    摘要:

    东天山-甘肃北山北带分布着众多镁铁-超镁铁质岩体,共同受控于康古尔-黄山大断裂,已证实该区带是岩浆型Cu-Ni-(PGE)硫化物矿床的重要产地,区域成矿地质条件良好。甘肃省地矿局第三勘查院在北山北带通过实施省地质勘查基金项目,首次发现了一处小型岩浆熔离型铜镍矿床,矿体形态复杂,深部矿化有待进一步验证,已具备成为中型铜镍硫化物矿床的潜力,该矿床的发现对拓展北山北带铜镍矿找矿思路和找矿方向具有重要意义。

    Abstract:

    There are many Mafic - ultramafic rock masses distributed in the Beishanbei belt of East Tianshan-Gansu Province, which are jointly controlled by Kangguel-Huangshan fault. It has been proved that this belt is an important origin of magmatic Cu-Ni- (PGE) sulfide deposit with favorable regional metallogenic geological conditions. The Third Exploration Institute of Gansu Provincial Bureau of Geology and Mineral Resources, through the implementation of the provincial geological exploration fund project, discovered for the first time a small magmatic melting type Cu-Ni deposit in the Beishan North Belt. The ore form is complex, the deep mineralization needs to be further verified, and it has the potential to become a medium Cu-Ni sulfide deposit. The discovery of this deposit is of great significance to expand the prospecting idea and direction of the Cu-Ni deposit in the Beishan North Belt.
