内容記述 | Isotopic ratios of ^<24>(Mg)/^<25>(Mg) and ^<26>(Mg)/^<25>(Mg) have been measured for Mg-rich and Al-poor portions of matrix areas of ALH-77278 and -77307 meteorites by ion microprobe mass spectrometry. The magnesium isotopic ratios for the meteorites were compared with that for a terrestrial forsterite of laboratory standard. Clear excesses of ^<24>(Mg) up to 10 permil have been found for the portions where concentration ratio of Al/Mg was less than 0.1 and that of Mg/Si was between 1.8 and 2.2. | |||||||||
