The minerals constituting the Earth's upper mantle are nominally anhydrous silicates
(NAMs). However they do contain hydrogen as a trace element, decorating point defects in …

Mineral properties hold dominion over planetary behavior as their physical and thermal
properties control mantle circulation, plate tectonics, melting behavior, and crustal …

Crustal recycling at convergent plate boundaries is essential to mantle heterogeneity.
However, crustal signatures in the mantle source of basaltic rocks above subduction zones …

We present new, whole-rock major and trace element chemistry, including rare earth
elements (REE), platinum-group elements (PGE), and Re–Os isotope data from the upper …

The formation of cratonic mantle peridotite of Archean age is examined within the time frame
of Earth's thermal history, and how it was expressed by temporal variations in magma and …

Traditional inversion techniques applied to the problem of characterizing the thermal and
compositional structure of the upper mantle are not well suited to deal with the nonlinearity …

Since the first application of the 187Re–187Os isotope system to determine the timing of
melt extraction from peridotites twenty years ago, a plethora of studies have demonstrated its …

The concentrations of Rh, Au and other highly siderophile elements (HSE: Re, Os, Ir, Ru, Pt,
Rh, Pd and Au), and 187Os/188Os isotope ratios have been determined for samples from …

The existence of different mantle domains exposed in ocean–continent transition zones
provides a framework for understanding the generation of ultramafic seafloor along magma …

We performed a thermodynamic and experimental study to investigate the fate of pyroxenite-
derived melts during their migration through the peridotitic mantle. We used a simplified …
