| 摘 要： | 对贵州断杉、纳水以及广西柳桥3条深水相剖面上的二叠系-三叠系界线附近黏土岩的研究结果表明,在断杉、柳桥剖面黏土岩中的黏土矿物主要由伊-蒙混层、蒙脱石和高岭石组成,碎屑物质中存在六方双锥石英、锆石等与火山活动有关的矿物;在纳水剖面黏土岩中未发现与火山活动有关的迹象.由此可知华南大部分地区在晚二叠世曾受强烈的火山作用影响,但也有少部分深水相地区未受影响或影响很小.同是深水相P-T界线剖面附近的黏土岩以及同一剖面不同层位的黏土岩中的黏土矿物和碎屑物质存在较大的差异,其原因可能是与火山作用的强弱、离火山活动中心的远近以及所处地理位置有关. |

| Abstract: | This paper employs clay stone analysis to Permian-Triassic boundary strata from three deep water sections,Duanshan,Nashui and Liuqiao,located in Guangxi and Guizhou region,southwestern China.The result shows that clay stones from the three localities are composed of illite-montmorillonite mixed layer,montmorillonite and kaolinglite.There are rock fragments such as bipyramid quartz and zircon which are related to volcanic process found in all the sections except in Nashui section.This would imply that extensive volcanism did great effect on most part of South China,whereas some deepwater environment was not or nearly not affected.The clay mineralogy composition and clast composition difference between different section or different levels in one section may result from variable intension of the volcanism,distance from the volcanism center and paleogeographical location. |
| Keywords: | deep-water facies Permian-Triassic boundary clay stone Guangxi and Guizhou region South China |
