摘要
综述了深海二叠(P)—三叠系(T)界线研究现状,介绍了深海P—T界线附近岩石地层、生物地层、缺氧事件及生物绝灭和复苏的研究进展,指出了深海P—T界线、缺氧事件和生物绝灭研究的分歧、不足及其症结。
The research on the Permo Triassic mass extinction and its cause is one of the forward fields of the modern geology,and is carried on in the continental,shallow-sea and deep-sea stratigraphy.The recent studies on the deep-sea Permo-Triassic boundary and events are reviewed in this paper.The developments are introduced in the lithostratigraphy,biostratigraphy,anoxic event,extinction and recovery near deep-sea Permo Triassic boundary.The different opinions,insufficiency and their cause in research on deep-sea Permo-Triassic boundary,anoxic event and mass extinction are pointed out.
