中文摘要:
      黔中断裂带形成于早古生代之前,是黔中重要的控岩-控矿构造复合带。本文通过对该断裂带特征及铀成矿关系分析研究,运用现代热液成矿理论,打破以往沉积-表生成矿思维束缚,认为断裂带内铀成矿的核心是构造和热液作用的叠合,成矿机制是幔源含U流体活动的参与和深部热液流体多次叠加改造,铀源主要为富铀的黑色岩系和晚中生代玄武岩;铀矿体主要赋存部位为断裂带上盘次级构造、层间破碎带,其次为断裂带局部,构造与热点复合地段是很好的铀成矿部位。
英文摘要:
      The fault zone of the centre Guizhou was formed before the Early Paleozoic and it’s an important rock-control,ore-control,structural complex zone in central GuiZhouIn this paper,based on the analysis and study from the fault zone characteristics and its uranium mineralization relationship,using modern hydrothermal metallogenic theory,breaking the shackles of sedimentary-surface metallogenic thinking in the past,it’s thought that the core of fault zone uranium mineralization is the superposition of tectonic and hydrothermal processesAnd the metallogenic mechanism is the participation of mantle-derived U-bearing fluids and the multiple superimposition and transformation of deep hydrothermal fluidsThe uranium sources are mainly uranium-rich black rock series and late Mesozoic basaltsThe main uranium ore bodies are located in secondary structures in the upper plate of fault zone and interlayer fracture zone and secondly local fault zoneEspecially,the composite zone of structure and hot spot is very good uranium mineralization location
