在进行大面积区域调查或干旱地区水化学找矿时,由于水源点稀少,会给远景区评价带来一定困难,查清古水文地质条件可以弥补不足。众所周知,铀是亲大陆性的,目前世界上无论老地层还是中、新生代地层中,几乎90％左右的铀矿床形成,都是用铀被地表水、地下水(含热水)淋滤、搬运和沉淀、富集来解释。因此,结合放射性水化学资料,加强对古水文地质条件与铀的地球化学关系的研究,特
During large-area survey or water-chemical prospecting in arid areas, the scarcity of water source points will cause some difficulties in the assessment of the vista. It is not possible to find out the paleo-hydrogeological conditions. It is well-known that uranium is pro-continental. At present, nearly 90% of the uranium deposits are formed in the old strata, middle-to-younger Cenozoic strata in the world and are all leached with uranium by surface water and groundwater (including hot water) And precipitation, enrichment to explain. Therefore, combined with radioactive aquatic chemical data to strengthen the ancient hydrogeological conditions and the relationship between uranium geochemistry, special
