Initially, it may seem extremely daunting to be sitting in front of several thousand carats of
small diamonds, knowing that the likelihood of finding a diamond with a meaningful …

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

Chemical geodynamics is an integrated discipline that studies the geochemical structure
and tectonic evolution of geospheres with the aim of linking tectonic processes to …

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 …

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 …

Modeling of melt formation and transport in all tectonic settings requires the inclusion of
water, since water has large effects on mantle solidi as well as physical properties of liquids …

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 …

Peridotite xenoliths from the Olmani cinder cone, northern Tanzania, possess distinctive
mineralogical and chemical features interpreted to result from interaction of ultra-refractory …

The mechanism of magmatransportat depth influences direction magma moves, the distance
it travels before freezing, the degree to which it communicates chemically with the host rock …

Understanding mantle melting above subduction zones requires an evaluation of the
behaviour of elements for which the mantle contribution greatly exceeds any subduction …
