Call for an improved set of decay constants for geochronological use
Age and isotopic relationships among the angrites Lewis Cliff 86010 and Angra dos Reis
The Sm-Nd history of KREEP
Sm-Nd whole rock measurements on a variety of KREEP-rich samples from different landing sites are reported. Despite a variation of Nd and Sm concentrations of almost a factor of 3, the Sm-Nd ratios,…
60Fe: A Heat Source for Planetary Differentiation from a Nearby Supernova Explosion
From a sample of the Semarkona (LL 3.0) ordinary chondrite we report the in situ discovery of 60Ni isotopic anomalies attributable to the decay of short-lived 60Fe (half-life 1.5 Myr) in the mineral…
Samarium-146 in the Early Solar System: Evidence from Neodymium in the Allende Meteorite
A carbon-chromite fraction from the Allende C3V chondrite shows strikingly large isotopic enrichments of neodymium-142 and neodynium- 143, providing an improved estimate of the original abundance of extinct samarium-146 in the early solar system.

Manganese–chromium isotope systematics of carbonaceous chondrites
Live Iron-60 in the Early Solar System
Isotopic analyses of nickel in samples from the differentiated meteorite Chervony Kut revealed the presence of relative excesses from the decay of the now extinct short-lived nuclide 60Fe, providing clear evidence for the existence of 60Fe over large scales in the early solar system.
