Analytical procedures of chemical analyses on volcanic glass shards by EDS with JEOL JED-2001 and JEOL JSM-5200 and the results of analyses are described. Moreover, the reliability of analyses are discussed. The results of 760 analyses on glass shards from the AT Tephra. indicating a mean SiO_2 content of 78.1 wt % and a standard deviation of 0.3 %, demonstrate the reproducible analytical work. Comparison of the data with that generated in different laboratories and with different equipment and techniques for the AT Tephra was undertaken. This comparison shows that the analytical accuracy of this measuring system is comparable with WDS and EDS results from other laboratories. This paper also deals with applicative studies of EDS, which are two cases of correlation of tephras. One is the correlation of the Ks 22 Tephra (500-780 ka) within the Kazusa Group in the Boso Peninsula with the KMT distributed in the west area of the Hida Mountains. The other correlation is between Km 1 Tephra within the Shimofusa Group in the Boso Peninsula and the Nuka 4 (ca. 300 ka) Tephra of the east foot the Yatsugatake Volcano.
