| 摘 要： | 迭部地区近东西向展布的系列台间坳陷控制硅灰泥岩富铀建造的分布,硅灰岩透镜体的空间展布和垂向延伸是制约铀矿体定位的条件。通过富铀建造条件、硅灰岩透镜体存在标志、构造-热液改造条件、放射性异常、化探组合异常等关键要素的叠合配置分析,认为白依背斜西北坳陷和占洼-刁德卡坳陷已知铀矿床深部和外围是扩大资源量的主要方向,太阳顶背斜北侧东段马克库地区和桑吉寺地区及太阳顶背斜南侧降扎-白依地区是开辟新找矿地段的有利地区。

| Abstract: | The uranium-rich formation of siliceous-limestone-mudstone was controlled by EW-striking depressions between platforms in Diebu.The spatial distribution of uranium orebodies are controlled by the horizontal and vertical extension of siliceous-limestone lenses.Analysis on the superposition of key ore-forming factors,including uranium-rich formation,siliceous-limestone lenses,structrue-hydrothermal alteration,radioactive anomaly and geochemical anomaly combination,etc.indicate that the northwest depression an... |
