摘要
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.
