238U/235U Systematics in Terrestrial Uranium-Bearing Minerals
The present-day 238U/235U ratio has fundamental implications for uranium-lead
geochronology and cosmochronology. A value of 137.88 has previously been considered …

Molybdenum isotopic evidence for the late accretion of outer Solar System material to Earth
Earth grew through collisions with Moon-sized to Mars-sized planetary embryos from the
inner Solar System, but it also accreted material from greater heliocentric distances …

A long-lived magma ocean on a young Moon
A giant impact onto Earth led to the formation of the Moon, resulted in a lunar magma ocean
(LMO), and initiated the last event of core segregation on Earth. However, the timing and …

Heterogeneous accretion, composition and core–mantle differentiation of the Earth
DC Rubie, DJ Frost, U Mann, Y Asahara… - Earth and Planetary …, 2011 - Elsevier
A model of core formation is presented that involves the Earth accreting heterogeneously
through a series of impacts with smaller differentiated bodies. Each collision results in the …

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 …
