Results are summarized of mass spectrometrical measurements of rare gases in the Yamato-74191 (L3) chondrite. The rare gas compositions in the Yamato-75258 amphoterite (type 6) were measured. Spallogenic gases dominate in He and Ne. Cosmic-ray irradiation and gas retention ages were tentatively calculated to be 12.4Ma and 30Ga, respectively. The concentration of trapped ^<132>(Xe) agrees with that inferred from the petrologic type.
