 note = {P(論文), Noble gas analyses for the inclusions and hosts from Yamato (Y)-75097,Y-793241 and Y-794046 have been performed. The concordant exposure ages as well as gas retention ages are observed between the host and the inclusion of each meteorite. These indicate that both experienced the same heating event and exposure history. High ^<129>Xe/^<132>Xe ratios (&cong;50) and neutron induced ^<80>Kr, ^<82>Kr and ^<128>Xe are due to very low concentrations of trapped noble gases in the inclusions from Y-75097 and Y-793241. This indicates a close genetic relationship and an early crystallization when ^<129>I was still alive. The inclusion of Y-794046,however, has a noble gas signature which is quite different from the other ones, suggesting a different origin. Negligible amounts of radiogenic ^<129>Xe and fissiogenic ^<136>Xe suggest a late formation.},
