Scientific paper

A stepwise heating technique was used on eight density separates from the neon-E rich phase G4j of the carbonaceous chondrite Orgueil to measure He, Ne and Ar. The density separation technique was found to further enrich the Ne-E carrier phases, allowing the Ne-E to be identified as virtually pure Ne-22. At least two separable carrier phases exist: (1) the l-carrier phase, which releases its Ne-E at temperatures below 900 C and is heavily enriched in the low-density separate; and (2) the h-carrier phase. The h-carrier is found to be highly retentive, with release temperatures above 900 C, and is associated with higher-density material. It is concluded that Ne-E and its carrier phases are probably of presolar origin.
