Abstract

The oxygen of anhydrous, high-temperature minerals in carbonaceous meteorites is strongly depleted in the heavy stable isotopes (17)O and (18)O. The effect is the result of nuclear rather than chemical processes and probably results from the admixture of a component of almost pure (16)O. This component may predate the solar system and may represent interstellar dust with a separate history of nucleosynthesis.

摘要

碳质陨石中无水、高温矿物的氧强烈缺乏重稳定同位素（17）O 和（18）O。这种效应是核过程而不是化学过程的结果，可能是由于混入了几乎纯的（16）O 成分所致。该成分可能早于太阳系形成，可能代表具有单独核合成历史的星际尘埃。
