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
