摘要 拉巴钼矿床位于格咱岛弧铜钼铅锌金银多金属矿集区,区域内岩浆构造活动非常强烈,成矿条件十分有利。矿体赋存于燕山晚期中酸性岩体-黑云母花岗闪长斑岩及其外接触带大理岩、矽卡岩和玄武岩中,矿床在时间上、空间上、成因上均与中酸性斑岩体有关。该矿床为受地层、构造和岩浆岩控制的斑岩型钼矿床。 Laba Mo deposit is located in the Cu-Mo-Pb-Zn-Au-Ag polymetallic ore-concentrated area of Geza Island Arc. With the intense magmatic-tectonic activities in this area, the deposit has favorable metallogenic conditions. The orebodies are hosted inside the late Yanshanian intermediate-acid intrusive bodies which include the biotite granodiorite-porphyry as well as marble, skarn and basalt in its outside contact zone. The deposit is in close relationship with the intermediate-acid porphyry in terms of time, space and genesis. The deposit is porphyry-hosted molybdenum deposit which is controlled by strata, structures and magmatic rocks.
