我们在1986—1988年调查研究莱州湾沿岸平原地下浓缩海水中的铀浓度时,发现该地区铀的浓缩倍数与海水浓缩倍数不成正比,有的要比后者高出几十倍。这种异常现象不仅是铀,其它微量元素也存在。研究地下浓缩海水中微量元素的地球化学异常行为,对研究地下浓缩海水形成的原因及扩大地下浓缩海水和化学资源的来源、开发利用均具有重要的意义。 When we surveyed the concentration of uranium in concentrated seawater in the plains along the Laizhou Bay from 1986 to 1988, we found that the uranium enrichment fold in this region is not proportional to the fold of seawater, but some tens of times higher than the latter. This anomaly is not only uranium but also other trace elements. Studying the geochemical anomalies of trace elements in underground concentrated seawater is of great significance for studying the reasons for the formation of underground concentrated seawater and for expanding the sources, development and utilization of underground concentrated seawater and chemical resources.
