| 摘 要： | 本文应用Ｘ射线衍射、红外光谱、差热分析，电子显微镜、化学分析、沉积相分析等方法，详细研究了贵州早、中三叠世间绿豆岩及其粘土矿物组成，确定了贵州绿豆岩中主要粘土矿物为伊利石、蒙脱石、高岭和伊利石／蒙脱石混层矿物。由于各地沉积环境和成岩条件的差异，分别形成伊利石粘土岩、蒙脱石粘土岩和高岭石粘土岩。探讨了绿豆及其粘土矿物的形成机理，为绿豆岩的开发利用提供了系统的新资料。

| Abstract: | Clay minerals in green-bean rocks ranging from Early to Midd1e Triassic in Guizhou Province have been identified by X-ray diffraction,infrared absorption,thermal analysis and scanning electron microscopy. The minerals include illite, smectite, kaolinite and a few illite/smectite interstratified clay minerals. With the green-bean rock as a synchronous marker,the 3m-thick sediment facies from its roof to thbottom have been studied and can be divided into 5 sediment-facies zones. Due to differences in depositional and diagenetic environments, illite,smectite and kaolinite were formed respectively in the studied area. The genesis of the green-bean rock and its clay minerals are also discussed. New systematic data are presented for the exploitation of green-bean rocks in this paper. |
