| 摘 要： | 分析了砂岩型铀矿的国内外研究现状和发展趋势，尝试从成矿系统演化论的角度提出新的研究思路：即，以系统观为指导，以物质迁移的动力学为主线，从区域地质背景演化，特别是构造动力演化、岩相古地理等方面入手，恢复矿前期、成矿期、矿后期的区域古地形格局。运用融入了地下水流动系统理论的古水文地质分析方法，重建区域演化进程中各地质时期的古流场。着重从区域尺度上研究矿质的源-迁移-汇（成矿）-保存的动力学过程。

| Abstract: | The research and current development trends of sandstone-type uranium deposit at home and abroad are analyzed. A new study idea is put forward in the view of evolution of metallogenetic system i.e. taking the dynamics of matter transportation as main clue to restore the regional palaeo-topography at pre-ore stage, ore forming stage and post-ore stage under the principle of system theory in the way of background evolution of regional geology, especially tectonic dynamic evolution and lithofacies and palaeogeography. Palaeo-flowing field at different geological periods in the processing of regional evolution is reestablished by the usage of palaeohydrogeological analysis combined with the theory of groundwater flowing system. Dynamical process of source-transportation-accumulation- reservation of metallogenetic matter is focused on region scale. |
