内容記述 |
The concentrations of rare gases and isotopic compositions of He, Ne and Ar were determined in twenty-four antarctic meteorites by rare gas mass spectrometry. No significant difference is found in cosmic-ray irradiation and thermal histories between antarctic and non-antarctic chondrites, except a discovery of extremely long irradiation age of 92 m.y. for the Yamato-74035 (L6) chondrite. The Yamato-75028 chondrite contains high concentrations of solartype rare gases. On the basis of rare gas data, two groups of paired meteorites were identified; they are Yamato-75097,-75102,-75108 and -75271,and Allan Hills-77015,-77167 and -77260. |
