Element Mapping of Volcanic Rock from Mt. Asama

Introduction

The minerals contained in rocks record physicochemical information from the time when the rocks were formed. Accordingly, it is possible to determine the thermal history and origins of rocks by a detailed investigation of the concentration distribution of their elements. Here, element mapping of volcanic rock from Mt. Asama in Japan was carried out using a Shimadzu EPMA™-1720HT EPMA electron probe microanalyzer. The thin-slice specimen for this analysis was provided by Mr. Hideto Yoshida (Technical Director, Technical Division, School of Science) Department of Earth and Planetary Science, Graduate School of Science, The University of Tokyo.
