摘要
阐述了中新生代山间坳陷盆地——新疆和什托洛盖盆地的水文地质、水文地球化学特征,认为该盆地具有完整独立的地下水补给、径流、排泄系统,为正向水文地质、水文地球化学分带的渗入型盆地.盆地经历了长期的水文地质淋滤作用,存在含铀含氧水不断渗入补给,认为在地下水交替缓慢的水动力区有利于形成砂岩型铀矿,分析了盆地的铀成矿条件,并优选出铀成矿的有利地段.
This paper elaborates the hydrogeologic, hydrogeochemical characteristic of the Heshituoluogai basin. The author considers that the basin is a intemontane depression Meso-cenozoic basin, it have the integrity independent groundwater replenishment,runoff and discharge system, it is a positive zoning infiltration type basin of hydrogeologic and hydrogeochemical. It experienced a long-term hydrogeologic leached function. Uraniferous and oxygenic groundwater continuously infiltrates through the basin and replenish it, and the slow-moving hydrodynamic zoning of the groundwater alternation is advantageous to forming a sandstone-type the uranium mineral. The text analyzes uranium metallogenic condition of the basin and provides the beneficial zoning of uranium mineral prospect.
