| Abstract: | 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. |

| Keywords: | the Permo-Triassic boundary anoxic event extinction and recovery deep-sea stratigraphy |
