The Yamato-75108 to-75257 chondrites are considered to be originally one meteorite which was broken into many fragments (MATSUMOTO, 1978; MATSUMOTO et al., 1979). Electron microprobe studies have been made on the olivine and orthopyroxene in ten chondrites (Yamato-75109,-75110,-75111,-75112,-75113,-75114,-75115,-75129,-75131 and -75139) out of these fragments. Textural characters of chondrules, matrix, igneous glass and secondary feldspar, and the mean composition, mean deviation, and percent mean deviation of olivines and orthopyroxenes are given. As a result, the chondrites are tentatively classified as L group and petrologic type 4-5. Accordingly, these chondrites were possibly one meteorite originally.
