Isotopic variations usually follow mass-dependent fractionation, meaning that the relative
variations in isotopic ratios scale with the difference in mass of the isotopes involved (eg …

The age of Jupiter, the largest planet in our Solar System, is still unknown. Gas-giant planet
formation likely involved the growth of large solid cores, followed by the accumulation of gas …

The short-lived Hf-W isotope system has a wide range of important applications in
cosmochemistry and geochemistry. The siderophile behavior of W, combined with the …

The isotopic composition of meteorites reveals a fundamental dichotomy between non-
carbonaceous (NC) and carbonaceous (CC) meteorites. However, the origin of this …

Understanding core formation in meteorite parent bodies is critical for constraining the
fundamental processes of protoplanet accretion and differentiation within the solar …

The 182 Hf-182 W chronology of iron meteorites provides crucial information on the
timescales of accretion and differentiation of some of the oldest planetesimals of the Solar …

Rocky asteroids and planets display nucleosynthetic isotope variations that are attributed to
the heterogeneous distribution of stardust from different stellar sources in the solar …

Nucleosynthetic isotope anomalies in bulk chondrites and differentiated meteorites reflect
variable proportions of isotopically diverse presolar components in bulk planetary bodies …

Abstract Coupled 187 Os/188 Os and highly siderophile element (HSE: Os, Ir, Ru, Pt, Pd,
Re) abundance data are reported for Apollo 12 (12005, 12009, 12019, 12022, 12038 …

Biostratigraphy underpins the Phanerozoic time scale, but its application to pre-Ediacaran
strata has remained limited because Proterozoic taxa commonly have long or unknown …
