摘要
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。
Investigation from 1986 to 1988 in the concentrated underground seawater of the area found geochemical anomaly of the minor elements. The causes are related to the sediments and the minor elements concentration in underground seawater of the Laizhou Bay.Because of the existence of ferromanganese nodule, the concentration of some minor elements in the concentrated underground seawater is much higher. The high uranium concentration in the concentrated underground seawater of the Laizhou Bay is probably due to the exi-stance of uranium in the sediments.Because of the relative constancy of water level and concentration, the concentrated underground seawater must have constant supplement.
