Research Abstract |
In Antarctica and Hokkaido, metamorphic rocks and a kind of granite(TTG) were collected, and were analyzed on the evolutions. I discovered a new mineral "Magnesiohogbomite-2N4S" from the metamorphic rock of Antarctica. The result was published in an international journal. I performed the age determination for this rock. Thereby, the CHIME age determination in Niigata University was completed mostly. On the TTG of Hokkaido, I recognized that the delamination is the important process for the origin of the TTG magma. I did invited presentation in the interational conference at Russia about the TTG.
