Relocation of syngenetic uranium may explain a characteristic feature of the deposits.

同生铀的重新分布可以用来解释矿床的一个典型特征。

The results show that thermoluminescent anomalies, whose two edges are higher and the middle is lower, indicate the uranium deposit, the rapidity step of natural voltage indicates the transitive section of oxidation-reduction.

通过室内和野外实测，结果表明土壤天然热释光异常曲线矿体边缘高值，矿体上方低值异常的曲线特征反映了铀矿化存在的可能；中间低值段越宽，起伏变化越小，矿化相对较好；低值段宽，但起伏变化相对较大，则矿体连续性变差；中间低值段狭窄，反映了矿化较差或没有矿化。

They reported the abnormal uranium content of waters issuing from tuffaceous rocks.

The results suggest that the uranium content and 234U/238U ratio s in the sandstone of the redox transition zone are generally higher than those of the oxidation and reduction zones,while the Th/U ratios of the transition zon e are lower than those in sandstone of the oxidation zone and the reduction zone .234U/238U and 230Th/238U ratios in uran ium ore samples are in the range of their ratios in the redox transition zone.

研究表明，与氧化带、还原带相比，氧化-还原过渡带具有较高U含量和234U/238U比值，较低Th/U比值；矿石样品中的234U/238U、230Th/ 238U比值位于过渡带范围内，234U/238U比值偏高区往往是过渡带分布区。
