Cratonic lithospheric mantle is composed of predominantly refractory materials that formed
at higher mantle potential temperatures (TP) than recorded in non-cratonic peridotites. It also …

During the past two decades significant progress has been made in understanding the
origin and evolution of kimberlites, including relationships to other diamondiferous magma …

Basalts and mantle peridotites of mid-ocean ridges are thought to sample Earth's upper
mantle. Osmium isotopes of abyssal peridotites uniquely preserve melt extraction events …

Although the diamond potential of cratons is linked mainly to thick and depleted Archean
lithospheric keels, there are examples of craton-edge locations and circum-cratonic …

To examine how the mantle lithosphere stabilises continents, we present a synthesis of the
mantle beneath Zealandia in the SW Pacific Ocean. Zealandia, Earth's “8th continent” …

The highly siderophile elements (HSE) consist of the Platinum Group Elements (PGE: Ru,
Rh, Pd, Os, Ir, Pt) along with rhenium and gold. These transition elements show relative …

A number of possible hypotheses have been proposed to explain the origin of mid-
lithospheric discontinuities (MLDs), typically characterized by∼ 2-6% reductions in seismic …

Tectonically emplaced mantle rocks, such as ophiolites, abyssal peridotites, and orogenic
peridotite massifs, provide a principle constraint on the composition of and processes in the …

Abstract The Re-Os isotopic system is largely considered the geochronometer of choice to
date partial melting of terrestrial peridotites and in constraining the evolution of Earth's …

Tellurium stable isotope compositions and abundances (δ 128/126 Te relative to SRM 3156)
are reported for 43 ordinary, enstatite, and Rumuruti chondrites, which together with results …
