研究実績の概要

The work has started by analysing samples available at Akita University. One short field campaign has also been conducted to collect more samples. The analyses so far have included mineral identification, chemical analyses and isotopic analyses. Most analyses have been conducted at Akita University. Additional analyses have also been made at commercial laboratories.
The work has been so far conducted in collaboration with one of the post-graduate students for the las year. He is expected to graduate at the end of this year.
The data obtained during these analyses will be compiled in a peer-reviewed publication in a specialised journal.

2: おおむね順調に進展している

理由

The limitations to travel imposed over the last year have made it impossible to gather new samples. However, samples collected previously have been used so far. Overall, the work has not been slowed by the current situation.

今後の研究の推進方策

In the future, more analyses will have to be performed. If the situation allows, we will travel to the field, mostly in Japan.

次年度使用額が生じた理由

The future work includes more analyses of the same type as the ones carried out over the last months. The work will also include travelling, if the situation allows.
