| 研究実績の概要 |
Research plans for the proposed project have been mainly achieved with some delay due to the COVID-19 outbreak and its effects.
Rocks samples collected during geological field surveys were investigated according to the plan.
Petrographic and textural details, mineral chemistry, and zircon single-grain EBSD analysis were conducted on potential samples. Then the deformed and undeformed domains within the zircon grains were analyzed, using the Nano-SIMS, for U-Pb isotope ratios and age dating. The results have been already presented at International conference, followed by publishing articles in international scientific journals. In addition, some of the research results are summarized, written as manuscript, and have been submitted to scientific journals which are currently under review.

理由
Although, the COVID-19 pandemic-related restrictions caused some delays in conducting the field and experimental works according to original plan. However, with limited traveling opportunities and ease in analysis last year, significant progress has been achieved. Further work on the proposed project is underway from which fruitful results are expected in the near future.
Data processing and manuscript preparations are in progress. In-situ EBSD analysis on additional samples have been done but isotopic work is still remaining that can be done during the current fiscal year.
|
| 今後の研究の推進方策 |
It is planned that Nano-Scale U-Pb and/or Pb-Pb isotope analyses on different domains within single zircon grains will be conducted during the current and last year of the the project. In addition, data already obtained in last year will be processed, illustrated, summarized, and the outcomes will be presented at international scientific conference and then published in scientific journals. Manuscripts on other works that are currently underway will also be prepared and published in scientific journals.

| 次年度使用額が生じた理由 |
Due to restrictions on travels and analytical works two years ago because of the COVID-19 pandemic, the funded amount was not transferred to the previous yearthat will be used in the next fiscal year.
