    摘要:

    赞比亚北部班韦乌卢地块受到古元古代乌本迪构造带、新元古代基巴拉构造带、新元古代伊鲁米德构造带及泛非期卢弗里安构造带的影响,主要分布有金、锰和金刚石矿床(点)。金矿床(点)主要赋存于姆波罗科索盆地东部姆巴拉组以紫红色砾岩—砂岩为主的碎屑沉积岩中,并且有较好的矿化线索。锰矿床主要分布在曼萨周围,可分为沉积型和构造型两类。班韦乌卢地块东部边缘发育含金刚石的钾镁煌斑岩和金伯利岩,在伊索卡地区前人利用重砂方法找到金刚石,推测地块内部可能寻找到含金刚石的钾镁煌斑岩和金伯利岩。因此,作者通过研究班韦乌卢地块的演化及其矿产资源现状,认为该地区具有较好的找矿潜力,可为中资矿业企业的矿权登记及矿产开发等方面提供基础的地质资料和科学依据,符合国家实施的矿产资源勘查开发“走出去”战略和“一带一路”战略。

    Abstract:

    Bangweulu Block of northern Zambia is affected by Paleoproterozoic Ubendian tectonic zone, Neoproterozoic Kibaran tectonic zone, Neoproterozoic Irumide tectonic zone and the Pan African Lufulian tectonic zone and there have gold,Manganese and diamond deposits (occurrence). Gold deposits(occurrences) mainly exist in Mbala Formation which include purple red conglomerate—sandstone clastic sedimentary rocks in eastern Mporokoso Basin and we find good gold mineralization clues.Manganese deposits are mainly distributed around Mansa which include sedimentary type and tectonic type. Bearing diamond lamproites and Kimberley are distributed in Bangweulu Block edge and predecessor found diamond using Heavy mineral method in Isoka area, therefore we think bearing diamond lamproites and Kimberley will be found inside Bangweulu Block. The authors study geodynamic evolution and mineral resources present research in Bangweulu Block and think the area has a good prospecting potential.We can provide geological data and scientific basis for the expansion of Chinese mining enterprises and mineral exploitation right registration which are fit for mineral resources exploration and exploitation of “go global ” strategy and “One Belt and One Road ” strategy of national implementation.
