A review of water contents of nominally anhydrous natural minerals in the mantles of Earth, Mars and the Moon
AH Peslier - Journal of Volcanology and Geothermal Research, 2010 - Elsevier
Olivine, pyroxene and garnet are nominally anhydrous but can accommodate tens to
hundreds of parts per million (ppm) H2O or “water” in the form of protons incorporated in …

Cratonic lithospheric mantle: Is anything subducted?
WL Griffin, SY O'Reilly - Episodes Journal of International Geoscience, 2007 - episodes.org
If the subcontinental lithospheric mantle (SCLM) formed through the repeated underthrusting
of oceanic slabs, peridotitic SCLM should resemble oceanic peridotites, and mafic rocks …

Major-and trace-elements in cratonic mantle eclogites and pyroxenites reveal heterogeneous sources and metamorphic processing of low-pressure protoliths
There is a growing body of evidence for the origin of cratonic mantle eclogite xenoliths by
low-pressure formation in now-recycled ocean floors. Because they have protoliths …

Fe3+ Distribution and Fe3+/ΣFe-Oxygen Fugacity Variations in Kimberlite-Borne Eclogite Xenoliths, with Comments on Clinopyroxene-Garnet Oxy-Thermobarometry
The valence state of iron in mantle-derived melts, such as mid-ocean ridge basalt, is a useful
proxy for oxygen fugacity (ƒ O2). On subduction, oceanic crust undergoes metamorphic …

Experimental calibration of a garnet–clinopyroxene geobarometer for mantle eclogites
Thermodynamic parameters have been calibrated for a geobarometer suitable for use on
eclogitic mantle xenoliths. The barometer is based on the incorporation of tetrahedrally …

Fractionation of oxygen and iron isotopes by partial melting processes: implications for the interpretation of stable isotope signatures in mafic rocks
Recycling of oceanic crust into the deep mantle via subduction is a widely accepted
mechanism for creating compositional heterogeneity in the upper mantle and for explaining …

Ultramafic carbonated melt‐and auto‐metasomatism in mantle eclogites: compositional effects and geophysical consequences
The mineralogy, chemical composition, and physical properties of cratonic mantle eclogites
with oceanic crustal protoliths can be modified by secondary processes involving interaction …

Compositional variations in primitive kimberlite melts and entrained mantle cargo from a global survey of trace element compositions in kimberlite olivine
Olivines are the dominant phase of kimberlites and the majority of grains display distinct
compositional zoning with xenocrystic cores surrounded by magmatic rims. Previous work …
