This volume is the part of the IGCP Project No. 203 carried out by the Chinese Research Group of P/Tr events based on abundant data from over 50 P/Tr sections in South China. The data were conducted by multiple methods such as lithofacial analysis, biofacial analysis, X-ray refraction, INAA, isotopic analysis, spectral analysis, electron probing analysis, electron scanning, etc. Five chapters in it are respectively devoted to transgression and regression events, volcanic event, geochemical anomalies and geological events, biotic mass extinction and biotic alternation at the P/Tr boundary, as well as ranking and scaling biostratigraphic events. As to marine transgression-regression, effect of volcanism on environment, level of biotic alternation and cause of mass extinction, some new opinions have been expressed. In addition, the authors have also given a concept of catastrophe-group which is concerned with a series of leading events, tributary events and the ultimate event.
