| 摘 要： | 通过对鄂尔多斯盆地罕台庙地区中侏罗统直罗组下段下亚段地层还原性的地质参数进行统计,发现该地层的还原性强弱与铀矿体的厚度、品位和平米铀量具有一定的关系。地层还原性较强或较弱,均不利于铀富集,仅在适当范围内,才有利于富铀矿体的形成,才能使铀矿体的厚度、品位和平米铀量达到最大值。因此,地层或砂体的还原性研究,对铀矿体的精确空间定位具有显著的指导性作用。

| Abstract: | This paper analysed the geological parameters of rock reducibility of the lower member of middle Jurassic Zhiluo formation in Hantaimiao area,Ordos basin.It was found that the intensity of reducibility of the strata was related to the thickness,grade and mass per square meters of uranium ore body.Strata with strong and weak reducibility could be adverse to the enrichment of uranium ore body,only the sequence with proper reducibility favors the relative accumulation of uranium mineralization. |
