| 摘 要： | 通过对十红滩铀矿床目的层中钙质砂岩的统计及其产出特征分析,认为钙质砂岩为顺层、断续分布的串珠状透镜体,产出空间界面位置为砂体的顶底部或冲刷面,岩性为粒度较粗、分选较好的砂岩。钙质砂岩累计厚度等值线图显示,钙质砂岩较集中地分布在矿体发育区。由此可见,氧化还原过渡带中钙质砂岩的形成与铀矿化具有一定的成因联系。

| Abstract: | It is considered that the calcareous sandstone appear at layer along of a bunch of pear lens on and off,localled near up and down surface of sandbody or washed surface,has sandstone of more macro-grain and more gradation through statistics and analysis of calcareous sandstone in goal layer in Shihong- tan uranium deposits.The calcareous sandstone accumulation thickness choro- gram demonstrated that the calcareous sandstone centralized distribution in the ore body growth area,thus it can be seen,in the oxidation reduction intermedi- ate belt the calcareous sandstone forms with the uranium mine has the certain origin relation.Choropleth map of summed thickness of calcareous sandstone deserves that it mainly appear in area of uranium body and related cause of for- mation of ore body of interlayer deacidizing-oxidation belt. |
