| 中文摘要: |
| 西宁盆地位于祁连造山带与西秦岭造山带交汇部位，已发现包马庄小型铀矿床，张家寨、汗庄、刹乙岭、三合村、石沿沟等砂岩型铀矿（化）点。本文通过对包马庄铀矿床典型矿床特征及铀矿化点特征的研究，认为区内砂岩型铀矿成矿前景较好，包马庄砂岩型铀矿加强钻探工作有可能发展为中型铀矿床，找矿有利区为西宁盆地北缘和南缘两个找矿远景区。 |
| 英文摘要: |
| The Xining basin is located at the intersection of Qilian orogenic belt and west Qinling orogenic belt. Some sandstone-type uranium deposits and occurrenes have been found, such as Baomazhuang small uranium deposit, Zhangjiazhai, Hanzhuang, Shayiling, Sanhecun and Shiyangou uranium occurrences. Study on the characteristics of the deposit and occurrences show that they are potential for further prospecting. Intensive drilling would make Baomazhuang small uranium deposit a medium size deposit and prospecting in future should be targeted at the south and north margi of Xining basin. |
