摘要 

研究了贵州省黔西县官坝地区二叠系—三叠系界线附近岩石样品的碳、氧同位素,结果表明,δ13C具有一个明显的负漂移,δ18O也具有明显降低特点。在界线附近发现的3层凝灰岩表明,在晚二叠世—早三叠世该区发生过火山活动。火山活动导致了沉积环境突变,致使二叠纪末发生了生物集群灭绝事件。

关键词 P-T界线黔西县官坝地区碳氧同位素凝灰岩    
Abstract

This study focuses on the C and O isotope signature for the rocks from the Permian?Triassic boundary in Guanba area of Qianxi, Guizhou Province. The result reveals that δ13C has a distinct negative drift,and the δ18O drops abruptly. Three layers of tuff,recognized at the boundary,have recorded the volcanic events that occurred in late Permian to early Triassic in this area . The volcanic events led to the abrupt change of sedimentary environments and ultimately triggered the mass extinction during the end of Permian.

Key wordsPermian-Triassic boundary    Guanba area of Qianxi    C and O isotopes    tuff
