Outline of Final Research Achievements

Multidisciplinary research has been performed on the pelagic sequences of Triassic-Jurassic boundary from the Inuyama, Mino Belt and Akehama, Chichibu Belt, Japan, from the Waipapa Belt, N.Z. and Antalya, Turkey, in order to clarify the meditation process from oceanic acidification event. The results of this study suggest that oceanic neutralization, indicating by extraordinary compositions of sediments such as Ca rich, occurred after acidification, and then faunal turnover of microfossils such as radiolarians continuously happened in a short duration <100kyr. This phenomenon strongly linked to the end Triassic mass extinctions suggested by a negative peak of stable Carbon isotopic ratios and also decreasing of biogenic magnetite in sediments.
