| 摘 要： | 可地浸砂岩铀矿储量计算中所需的岩矿石密度,目前用取样测定法--石蜡法获得,而放射性物探方法之一γ-γ散射测井作为参考.笔者在新疆吐哈盆地某铀矿床密度测定中,对2种方法测定的密度结果进行了资料整理、研究对比,认为后者完全可以取代前者,提供准确的岩矿石密度值.

| Abstract: | The rock and mineral densities required in the calculation of the reserves of sandstone uranium deposits are determined at present by the sampling determination method?paraffin method, and theγ-γscattering logging, one of the radioactive geophysical techniques, is used for reference. In the density determination for a certain uranium deposit in Tuha basin of Xinjiang, the author made data arrangement and comparison of the determination results of the two techniques, and has thus reached the conclusion that the latter technique can be undoubtedly used in place of the former to provide accurate density values of rocks and minerals. |
