| 研究実績の概要 |
I have carried out field surveys at Miyakejima and Shinmoedake to collect geological samples. These samples have been prepared for analytical work to be undertaken at the Geological Survey of Japan. I have finalized the method for integrating crystal orientation and compositional data for orthopyroxene in volcanic rocks. This work has been submitted as a manuscript and is accepted in a high impact factor, open access international journal. I have tested the method for integrating crystal orientation and compositional data for olivine in volcanic rocks, and data collection is ongoing for this part of the project.

2: おおむね順調に進展している
理由
Generally, this project has been progressing as planned. Field surveys were successful, thanks to suitable planning and weather. Laboratory closures during March to May have slightly delayed data collection.
|
| 今後の研究の推進方策 |
Data collection will proceed as planned for the project, despite some delays due to laboratory closures. Because of international travel restrictions, attendance at conferences in Greece and New Zealand may be postponed.
|
| 次年度使用額が生じた理由 |
Due to some laboratory closures, spending on analytical expenses was delayed and will be undertaken in the next fiscal year instead.
