| 摘 要： | 黏土岩是高放废物地质处置库重要的候选围岩之一。通过野外地质勘查,查明塔木素地区黏土岩产状平缓、分布广泛、沉积环境稳定。采用薄片鉴定、X射线衍射及扫描电镜分析等方法,研究了该地区黏土岩的岩石学和矿物学等特征,结果表明,岩石具泥质结构、致密块状构造,黏土矿物主要为高岭石、伊利石等。研究初步认为该地区黏土岩基本满足高放废物地质处置库围岩的要求。

| Abstract: | Claystone is one of the important candidate host rocks of the repository for high-level radioactive waste geological disposal. Geological prospecting has been conducted on the clay formation in Tamusu area, Inner Mongolia Autonomous Region, which suggested that the clay formation in Tamusu area were formed in a stable sedimentary environment with widely extending horizontal stratum. Further studies on petrology and mineral characteristics by X-ray diffraction and SEM analysis indicated that the clays are mainly composed of kaolinite and illite with the politic texture and compact structure. The preliminary results of this study showed that the clay formation meets the requirements basically as the host rocks for high-level radioactive waste geological disposal. |
