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

Convergent plate boundaries are key sites for continental crustal formation and recycling.
Quantifying the evolution of crustal thickness and paleoelevation along ancient convergent …

Mare volcanics on the Moon are the key record of thermo-chemical evolution throughout
most of lunar history,–. Young mare basalts—mainly distributed in a region rich in …

The end-Triassic extinction is characterized by major losses in both terrestrial and marine
diversity, setting the stage for dinosaurs to dominate Earth for the next 136 million years …

Arc magmas are important building blocks of the continental crust. Because many arc lavas
are oxidized, continent formation is thought to be associated with oxidizing conditions. On …

We present a comprehensive geochemical data set for the most recent volcanics from the
Mariana Islands, which provides new constraints on the timing and nature of fluxes from the …

This paper presents the first comprehensive major and trace element data for∼ 130 abyssal
peridotite samples from the Pacific and Indian ocean ridge–transform systems. The data …

The trace element composition of olivine is a rapidly growing research area that has several
applications of great potential. Mantle olivines can be distinguished from volcanic olivines by …

Because of their distinct chemical signatures, ocean-island and mid-ocean-ridge basalts are
traditionally inferred to arise from separate, isolated reservoirs in the Earth's mantle. Such …

Vanadium exists in multiple valence states in silicate and oxide systems, namely V2+, V3+,
V4+ and V5+. This special characteristic has been exploited in several ways to estimate the …
