Abyssal peridotites are ultramafic rocks collected from mid-ocean ridges that are the
residues of adiabatic decompression melting. Their compositions provide information on the …

Redox-sensitive transition group elements are involved in almost all fundamental
geochemical processes. Of these elements, vanadium (V) contributes a particularly powerful …

We derive an estimate for the chemical composition of the depleted MORB mantle (DMM),
the source reservoir to mid-ocean ridge basalts (MORBs), which represents at least 30% the …

We present an estimate for the composition of the depleted mantle (DM), the source for mid‐
ocean ridge basalts (MORBs). A combination of approaches is required to estimate the …

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 …

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 …

The influence of water on the dynamics of the oceanic upper mantle is re-evaluated based
on recent experimental constraints on the solubility of water in mantle minerals and earlier …

Basalts and basaltic rocks are the most abundant igneous rocks on the earth and their
petrologic and geochemical studies have formed our knowledge base on the thermal …

Abstract Ocean Drilling Program Leg 125 recovered serpentinized harzburgites and dunites
from a total of five sites on the crests and flanks of two serpentinite seamounts, Conical …

Abstract Early History of Mantle GeochemistryUntil the arrival of the theories of plate
tectonics and seafloor spreading in the 1960s, the Earth's mantle was generally believed to …
