Fossil fission tracks have been found in a coarse-grained white inclusion of the Allende chondrite. Tracks are present in excess of those produced by 238 U spontaneous fission and cosmic rays. The ratio of excess tracks to 238 U tracks is ∼20, inte

This paper presents results of a fission track investigation of the minor mineral phase chromite in the Allende meteorite. Although this mineral is a possible carrier of much of the meteorite's isotopically anomalous xenon, there are at least two ord

Certain meteorites contain stored fission track densities that are in excess of those that can be attributed to the spontaneous fission of uranium. Previous work has shown that the most likely source of these tracks is the spontaneous fission of exti

Noble gas elemental and isotopic ratios were measured in a group of 13 "chondritic" stratospheric dust particles. Neon and argon are present in "solar" proportions; xenon appears to be dominated by contributions from "planetary" sources. The apparent
