新疆晚古生代裂谷中同生断裂的控矿问题

On Ore-controlling of Contemporaneou fault of the Late Paleozoic Rifts in Xinjiang

新疆晚古生代裂谷中同生断裂具有明显的控矿作用,体现出"三同一体"和多组断裂构造交会的区域构造特征。以构造的不同级别、期次,对矿带、矿田、矿床予以控制,在构造交会和构造复合地段使矿田或矿床就位。由于构造的近等距性发育,从而制约矿田或矿床的近等距分布,更由于裂谷同生断裂的多次开合和地质动力性质转换,形成了多层次、多形式、多矿种、多类型、且具有矿种分带性的综合矿产链。

The contemporaneous fault controls ore of Xinjiang late-palaeozoic rift. It is sharacterized by＂ three problem in one＂ and fault crossing. Ore belt. ore field and ore deposit are controled by the structure of diffient class and diffient peried. Ore field or ore deposit locates in crosing of structure and compounding of structure. Owing to tectonic growth of near equal range are resulting in relationship of the near equal range ore field and ore deposit. Basing on the polyopening-clossing of rift and the change conversions of geodynamic are composed compound ore zones of polyofemic ,poly-shape ,poly-ore ,poly- type and belting.
