| 摘 要： | 从矿田现代温热水入手，运用水文地球化学、同位素水文地质等手段，结合地热基础理论与方法，剖析了典型矿床地温特征，对温热水的补给源、热源进行了研究；结合铀成矿机理分析，探讨了热水与铀成矿作用的关系．认为相山矿田温热水属隆起断裂型热水，大气降水为温热水的主要补给源，地下水深循环及放射性生热为温热水获得热量的主要途径，热水活动对铀成矿作出了重要贡献，铀源主要来自水-岩作用，形成了受基底构造和火山盖层构造联合控制的地温高场、温热水及铀矿化于一体的空间组合．

| Abstract: | Xiangshan uranium orefield is one of the largest volcanic rock type hydrothermal uranium orefield in China. Beginning with modern warm hot-water in the orefield, and applying hydrogeochemistry and isotopic hydrogeology, this paper (analyzes) the geothermal characteristics of typical deposits, studies supply and heat sources of warm hot-water, and discusses the relation between hot-water and uranium mineralization according to the mechanism of uranium metallogenesis. The warm hot-water in Xiangshan orefield is hot-water of uplift fault type, meteoric water is the major supply source of warm hot-(water); deep circulation of groundwater and radioactive heat are the main channels for warm hot-water to obtain heat energy; hot-water activity made an important contribution to uranium metallogenesis; the uranium source mainly comes from water-rock interaction; a space unit is formed on integration with geothermal high field, warm hot-water and uranium mineralization which are controlled by base tectonics and volcano cover structure. |
