| 中文摘要:文章依据放射性水文地球化学找矿理论，运用花岗岩热液铀矿水异常晕与铀矿化之间的关系，采用R型逐步聚类分析方法，通过对下庄矿田北部330矿床及其外围水化学资料的统计整理，对铀矿床水分散晕指示元素(或指标)的组成及其分带性进行了初步探讨，认为该矿床水分散晕指示元素和指标由U、SO2-4、F-、Al3+、Mg2+、Cr、Ni、Mo、Pb、As、Bi、Mn、M(矿化度)等组成，而且，这些元素和指标具有分带规律。 |

| Abstract:The rational appraisal of water anomalies is a key technology in the radioactive hydrogeochemical prospecting. Based on radioactive hydrogeochemical prospecting theory, utilizing the relationship between water anomalous halos and uranium mineralization in the granitic hydrothermal uranium deposit, and adopting R type successive cluster analysis method, the authors arranged the hydrogeochemical materials of 330 deposits in the north of the Xiazhuang orefield and its periphery, and preliminarily discussed the composition of the indicator elements in water dispersion halos of the uranium deposit and their zoning. It is considered that the indicator elements of water dispersion halos in such a deposit consist of U, SO2-4, F-, M, Al3+, Mg2+, Cr, Ni, Mo, Pb, As, Bi, Mn etc., which also exhibit zonation. |
