One of the most contentious areas of Earth Science today is when, or whether or not modern-
style plate tectonics was in operation in the Archean Eon. In this review we present evidence …

An accurate assessment of the bulk chemical composition of Mars is fundamental to
understanding planetary accretion, differentiation, mantle evolution, the nature of the …

Non-arc basalts of Archean and Proterozoic age have model primary magmas that exhibit
mantle potential temperatures TP that increase from 1350° C at the present to a maximum …

Comparing compositional models of the terrestrial planets provides insights into
physicochemical processes that produced planet-scale similarities and differences. The …

In order to test accretion simulations as well as planetary differentiation scenarios, we have
integrated a multistage core–mantle differentiation model with N-body accretion simulations …

An upgrade of the PRIMELT algorithm for calculating primary magma composition is given
together with its implementation in PRIMELT3 MEGA. xlsm software. It supersedes …

Melting experiments on fertile peridotite KR4003, a 'pyrolitic'composition, were made from 3
to 7 GPa in piston-cylinder and multi-anvil apparatus. Temperature gradients across the …

Results are reported of an exploration of mantle source lithology for intraplate magmas
using whole-rock and olivine phenocryst compositions. This analysis includes modern mid …

More than 50 per cent of the Earth's upper mantle consists of olivine and it is generally
thought that mantle-derived melts are generated in equilibrium with this mineral. Here …

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 …
