Journal of Geophysical Research: Solid Earth, 2020 Melt-peridotite interaction has the ability to modify the delta Fe-56 of peridotite. However, iron isotopic fractionation during melt-peridotitc interaction is not well understood at present.

Global variations in abyssal peridotite compositions
Lithos, 2016 Publisher's PDFAbyssal peridotites are ultramafic rocks collected frommid-ocean ridges that are the residues of adiabatic decompression melting. Their compositions provide information on the degree of melting and melt–rock interaction involved in the ...

Melting of Peridotite to 140 Gigapascals
Science, 2010Under Pressure In order to understand the behavior of materials in the solid deep Earth, it is important to be able to estimate how a material melts at high pressure. To this end, Fiquet et al. (p.

Tectonics, 2018 One of the largest ophiolitic peridotite masses in the world covers a quarter of the island of Grande Terre, New Caledonia. The Peridotite Nappe was obducted during the Eocene, is weakly deformed and corresponds to the highest of a structurally simple ...

Orogenic, Ophiolitic, and Abyssal Peridotites
2007"Tectonically emplaced" mantle rocks include subcontinental, suboceanic, and subarc mantle rocks that were tectonically exhumed from the upper mantle and occur:(i) as dispersed ultramafic bodies, a few meters to kilometers in size, in suture zones and mountain belts (i.e., the "alpine," or "orogenic" peridotite massifs - De Roever (1957), Thayer (1960),

The partial fusion of peridotite
Bulletin Volcanologique, 1964In a study of the origin of basalt magma, peridotite has been partially fused and the composition of the liquid phases determined.

Weathering crusts on peridotite
Contributions to Mineralogy and Petrology, 2015Chemical weathering of dark-green massive peridotite, including partly serpentinized peridotite, produces a distinct and remarkable brown weathering rind when exposed to the atmosphere long enough. The structure and mineral composition of crusts on rocks from the Ronda peridotite, Spain, have been studied in some detail.

The origin of abyssal peridotites: a new perspective
Earth and Planetary Science Letters, 1997Abyssal peridotites have been interpreted to be residues of mantle melting beneath ocean ridges. Recent experimental data and models of mantle melting allow quantitative tests of this hypothesis. The tests show that abyssal peridotites are not purely melting residues.

Rhodium, gold and other highly siderophile elements in orogenic peridotites and peridotite xenoliths
Chemical Geology, 2011Abstract The concentrations of Rh, Au and other highly siderophile elements (HSE: Re, Os, Ir, Ru, Pt, Rh, Pd and Au), and 187Os/188Os isotope ratios have been determined for samples from peridotite massifs and xenoliths in order to further constrain HSE abundances in the Earth's mantle and to place constraints on the distributions processes ...

Serpentinites, Peridotites, and Seismology
International Geology Review, 2004Understanding the physical properties of ultramafic rocks is important for evaluating the wide variety of petrologic models for the Earth's upper mantle and lower oceanic crust.
