4th July 2024

A new paper has been published in the JpGU flagship journal PEPS. It is a report of a very unusual garnet peridotite from an oceanic domain and its implications for convection in the Asthenosphere. Several of the authors are or were members of the Petro-Tectonics seminar: N. Akizawa, K. Ozawa, S. R. Wallis, T. Nagaya, and C. Ohshima

1st July 2024

A new paper about carbonaceous material Raman thermometry has been published with many of authors members of the Nagoya and Tokyo ganko groups: Simon Wallis, Yui Kouketsu, Mutsuki Aoya and Ken Yamaoka. The paper provides an automated way to process Raman spectra, and we hope it will save a lot of time for people trying to estimate metamorphic temperatures.

Dr Soejima and Prof Wallis joined a JpGU field trip to the south of the Boso peninsula to see structures of the young accretionary complex It is highly unusual to be able to see such a young accretionary complex formed at only a few kilometers at the Earth's surface.
