Origin and evolution of the atmospheres of early Venus, Earth and Mars
We review the origin and evolution of the atmospheres of Earth, Venus and Mars from the
time when their accreting bodies were released from the protoplanetary disk a few million …

The accretion of planet Earth
AN Halliday, RM Canup - Nature Reviews Earth & Environment, 2023 - nature.com
Earth's origins are challenging to elucidate, given the lack of surviving terrestrial geology

Bifurcation of planetary building blocks during Solar System formation
Geochemical and astronomical evidence demonstrates that planet formation occurred in two
spatially and temporally separated reservoirs. The origin of this dichotomy is unknown. We …

Geophysical and cosmochemical evidence for a volatile-rich Mars
Constraints on the composition of Mars principally derive from chemical analyses of a set of
Martian meteorites that rely either on determinations of their refractory element abundances …

Evaporation of moderately volatile elements from silicate melts: experiments and theory
Moderately volatile elements (MVEs) are sensitive tracers of vaporisation in geological and
cosmochemical processes owing to their balanced partitioning between vapour and …

Zinc isotope composition of the Earth and its behaviour during planetary accretion
The terrestrial planets are depleted in volatile elements with respect to chondritic meteorites,
their possible building blocks. However, the timing, extent and origin of volatile depletion is …

Fe and Mg isotope compositions indicate a hybrid mantle source for young Chang'E 5 mare basalts
Abstract The Chang'E 5 (CE-5) samples represent the youngest mare basalt ever known
and provide an access into the late lunar evolution. Recent studies have revealed that CE-5 …

Near-equilibrium isotope fractionation during planetesimal evaporation
Silicon and Mg in differentiated rocky bodies exhibit heavy isotope enrichments that have
been attributed to evaporation of partially or entirely molten planetesimals. We evaluate the …

Early volatile depletion on planetesimals inferred from C–S systematics of iron meteorite parent bodies
MM Hirschmann, EA Bergin… - Proceedings of the …, 2021 - National Acad Sciences
During the formation of terrestrial planets, volatile loss may occur through nebular
processing, planetesimal differentiation, and planetary accretion. We investigate iron …

An inner solar system origin of volatile elements in Mars
The origin of volatile elements in Mars and whether these elements derive from the inner or
outer solar system is unclear. Here we show that Mars exhibits nucleosynthetic zinc (Zn) …
