The rate of natural carbonation of tectonically exposed mantle peridotite during weathering
and low-temperature alteration can be enhanced to develop a significant sink for …

Mantle peridotite xenoliths from Archean cratons generally have high molar Mg/(Mg + Fe),
or Mg#. The best known suites, from the Kapvaal and Siberian cratons, have high modal …

Introduction Limited data is available from studies that directly compare oncoplastic breast
surgery and conventional breast-conserving surgery (CBCS) procedures. The aim of this …

This paper presents results of modelling reaction between peridotite and fractionating
tholeiitic basalt in simple and complex silicate systems. Reactions are outlined in appropriate …

Many mantle peridotite samples are too rich in Si0 2 (in the form of orthopyroxene) and have
ratios of light to heavy rare earth elements that are too high to be consistent with an origin …

Like residual peridotites from mid-ocean ridges, peridotites from the mantle section of the
Oman ophiolite are far from equilibrium with mid-ocean-ridge basalt (MORB). By contrast, …

Exposed, subduction-related magmatic arcs commonly include sections of ultramafic plutonic
rocks that are composed of dunite, wehrlite, and pyroxenite. In this experimental study we …

The continental crust has an andesitic composition with high Mg/(Mg+Fe) and Ni contents
which may be too high to have formed by differentiation of basaltic magmas. Instead, mantle-…

We review physical and chemical constraints on the mechanisms of melt extraction from the
mantle beneath mid–ocean ridges. Compositional constraints from MORB and abyssal …

Three distinct groups of eclogites (low-Mg–Ti eclogites, high-Ti eclogites and Mg-rich eclogites)
and ultramafic rocks from the depth interval of 100–680 m of the Chinese Continental …
