Since the first discovery of extraordinary oxygen isotope compositions in carbonaceous meteorites by Clayton et al. [Clayton, R.N., Grossman, L., Mayeda, T.K., 1973. Science 182, 485–488], numerous studies have been done to explain the unusual mass

Surface-correlated noble gases in lunar soils are primarily implanted SW (solar wind) noble gases. However, they also include apparently orphan radiogenic 40 Ar, 129 Xe, and 244 Pu-derived fission Xe in excess of plausible primordial solar origin. Th

The Labrieville anorthosite massif (LBV) is found in the Central Granulite Terrain of the Grenville Structural Province, but it displays no evidence of post-emplacement deformation or metamorphism, implying intrusion following peak Grenvillian metamo

Correlations between the amounts of Xe129 and Xe128 released in stepwise heating of neutron-irradiated meteorites are used to determine the initial ratio I 129 I 127 and hence a relative formation time for the various samples. In such an experiment,

Spallation yields of krypton and xenon from irradiation of strontium and barium with 730 MeV protons
Publikováno v:

We have studied mass spectrometrically the krypton and xenon isotopes resulting from spallation of strontium and barium by 730 MeV protons. We report the cross sections for chain yields of 7 krypton isotopes (2 radioactive) and 9 xenon isotopes (1 ra

The abundance ratio 244 Pu 238 U at the time the St. Severin meteorite began to retain xenon has been determined to be0.0127±0.0026 by a method involving only xenon isotope ratio measurements.

Essentially all of the more equilibrated meteorites which contain excess radiogenic 129 Xe have well-defined I Xe formation intervals that apparently date the onset of proportional retention for iodine and radiogenic 129 Xe from the decay of 129 I. P

We reinterpret the xenon data from a stepwise heating of the Murray and Renazzo carbonaceous chondrites by Reynolds and co-workers and confirm the exceptionally large amounts of fission-produced xenon postulated by Reynolds' group. Our interpretation
