On 11th October, Dr. Katz SUZUKI from JAMSTEC gave an academic lecture on "Marine Os isotope as a tool to elucidate the processes of geological events".
He talked about the following topics as examples of application of the marine Os isotope based on their results.
1. Detailed processes of the snowball Earth and great oxidation events at approximately 2.3 Ga based on the Os isotope record in the Huronian Supergroup sedimentary rocks.
2. Oceanic anoxic events caused by massive volcanism in late Jurassic and Cretaceous.
3. Meteorite impact recorded in Os isotopic compositions of Triassic sedimentary sequence.
