内容記述 |
Three ordinary chondrites from the Yamato Mountains (Y) region of Antarctica contain cm-sized igneous inclusions being studied by a consortium. RNAA data for the labile elements Ag, Bi, Cd, Cs, Ga, In, Rb, Sb, Se, Te, Tl and Zn, and refractory Au and U in the L6 hosts of Y-75097 and Y-793241 indicate that each experienced at least one preterrestrial, high-temperature episode. This heating occurred during formation of the igneous inclusions and/or as a result of the severe shock that affected most equilibrated L chondrites. Cosmogenic 720ka ^<26>Al, and 301ka^<36>Cl (which are determined by AMS) in metal from these two meteorites and nominal terrestrial ages (based on ^<36>Cl) hint that the L6 chondrites are not paired but are inconclusive in this regard. RNAA data for the H chondrite host of Y-794046 generally resemble those of other H4-6 chondrites : its contents of cosmogenic radionuclides in general, and its ^<36>Cl content, in particular, correspond to a nominal terrestrial age of 70±60ka. |
