Chromium isotopic insights into the origin of chondrite parent bodies and the early terrestrial volatile depletion
Chondrites are meteorites from undifferentiated parent bodies that provide fundamental
information about early Solar System evolution and planet formation. The element Cr is …

Anatomy of rocky planets formed by rapid pebble accretion-I. How icy pebbles determine the core fraction and FeO contents
We present a series of papers dedicated to modelling the accretion and differentiation of
rocky planets that form by pebble accretion within the lifetime of the protoplanetary disc. In …

[HTML][HTML] Combined U-corrected Pb-Pb dating and 26Al-26Mg systematics of individual chondrules–Evidence for a reduced initial abundance of 26Al amongst inner …
Chondrites are fragments of asteroids that avoided melting and, thus, provide a record of the
material that accreted to form protoplanets. The dominant constituent of chondrites are …

Volatile-depletion processing of the building blocks of Earth and Mars as recorded by potassium isotopes
The stable potassium isotopic ratios (41 K/39 K) of Earth and Mars have been interpreted to
reflect either nucleosynthetic isotope anomalies or volatility-driven K depletion. Chondrites …

Loss and isotopic fractionation of alkali elements during diffusion-limited evaporation from molten silicate: Theory and experiments
Moderately volatile elements (MVEs) are variably depleted in planetary bodies, reflecting the
imprints of nebular and planetary processes. Among MVEs, Na, K, and Rb are excellent …

Chromium isotopic evidence for an early formation of chondrules from the Ornans CO chondrite
Chondrules are the main components of primitive meteorites and possibly the building
blocks of planetary embryos and terrestrial planets. However, their ages and modes of …

Evidence from achondrites for a temporal change in Nd nucleosynthetic anomalies within the first 1.5 million years of the inner solar system formation
Heterogeneity in isotopic compositions within the protoplanetary disc has been
demonstrated for a number of elements measured in extra-terrestrial materials, mostly based …
