Thank you for visiting my page. I am in Ph.D. Course at the Department of Earth and Planetary Science, the University of Tokyo. I am interested in how meteorite impacts effect on the Earth’s environment and studying on the Australasian Tektite Event. The Australasian Tektite Event (ca. 0.79 Ma) is the youngest among large impact events on the Earth. However, no impact crater has been found. Based on the distribution of tektites, the location of the impact has been estimated as somewhere in the eastern part of Indochina. The effects on the Earth’s environment that this impact has caused also are not known well. We are trying to identify the location of the impact by focusing on the ejecta layer in Indochina (strata composed of rock materials thrown out from the crater).
