We present He, Ne, and Ar data on stepwise heating experiments for the CM-2 chondrite LEW90500 and on noble gas isotopic abundances of the anomalous CK chondrite Maralinga. In LEW90500 we observe at least 0.20 x 10-8 ...

We report the results of SIMS isotopic analyses of carbon, nitrogen, oxygen, and silicon made on 849 small (~1 μm) individual silicon carbide grains from the Murchison meteorite. The isotopic compositions of the major ...
