Outline of Final Research Achievements |
Reconstruction of oceanic environment during Late Permian to Middle Triassic corresponding to the greatest mass extinction and its aftermath was conducted. Japanese deep-sea sedimentary rocks show record from the low lattitudinal oceanic area. Our study results indicate developments of hydrogen sulfide rich sea water condition at the end- Permian mass extinction and somewhat oxygen poor but not anoxic condition at the late Early Triassic. Deep-sea sedimentary records from New Zealand which located middle latitude show different history. Temporal development of hydrogen sulfide bearing water condition occurred at the mass extinction, but oxygen poor conditions are not detected at the late Early Triassic.These findings suggest that each oceanic areas have unique environmental histories during Permian to Triassic.
