TLDR
In this paper, the authors found that primary hydrous and other minerals enriched with incompatible components were found in ocean-floor ultramafic-mafic plutonic rock suites recovered from two contrasting ridge systems, i.e., the East Pacific Rise (Hess Deep, equatorial Pacific), a typical fast-spreading system, and the Mid-Cayman Trough, a typical slow spreading system.About:

Widespread arc-related melting in the mantle section of the northern Oman ophiolite as inferred from detrital chromian spinels
TL;DR: In this article, detrital chromian spinels, derived from the mantle section, were used to deterrmine whether the mantle peridotite of the northern Oman ophiolite is of oceanic or arc origin.

Mantle Melting, Melt Transport, and Delivery Beneath a Slow-Spreading Ridge: The Paleo-MAR from 23°15′N to 23°45′N
TL;DR: Kane Megamullion, an oceanic core complex near the mid-Atlantic Ridge (MAR) abutting the Kane Transform, exposes nearly the full plutonic foundation of the MARK paleo-ridge segment as mentioned in this paper.

Chemical characteristics of chromian spinel in plutonic rocks: Implications for deep magma processes and discrimination of tectonic setting
TL;DR: In this article, the chemical properties of chromian spinels from ultramafic to mafic plutonic rocks (lherzolites, harzburgites, dunites, wehrlites, troctolite, olivine gabbros) with respect to three tectonic settings (mid-ocean ridge, arc, oceanic hotspot) were summarized.

TL;DR: The first four rocks examined by the Mars Science Laboratory Alpha Particle X-ray Spectrometer indicate that Curiosity landed in a lithologically diverse region of Mars as discussed by the authors, collectively dubbed the Bradbury assemblage, were studied along an eastward traverse.

The Stability of Hydrous Mantle Phases
TL;DR: It is widely recognized that hydrous minerals are involved in a number of geochemical processes in the Earth's mantle (Michael 1988, Thompson 1992, Schmidt and Poli 1998) and can control the partitioning of trace elements during partial melting as discussed by the authors.

Chromian spinel as a petrogenetic indicator in abyssal and alpine-type peridotites and spatially associated lavas
Henry J. B. Dick,Thomas Bullen +1 more
TL;DR: The composition of chromian spinels in alpine-type peridotites has a large reciprocal range of Cr and Al, with increasing Cr# (Cr/(Cr+Al)) reflecting increasing degrees of partial melting in the mantle as mentioned in this paper.

Melting in the oceanic upper mantle: An ion microprobe study of diopsides in abyssal peridotites
TL;DR: In this article, a systematic study of rare earth and other trace elements in discrete diopsides from residual abyssal peridotites sampled from 5000 km of ocean ridge demonstrates that they are the residues of variable degrees of melting in the garnet and spinel peridotsite fields.

Structures of Ophiolites and Dynamics of Oceanic Lithosphere
TL;DR: In this article, the authors present an analysis of ophiolite structures in the context of oceanic lithosphere and asthenosphere and discuss the importance of the Ophiolites as markers of past plate tectonics.

Geochemical Consequences of Melt Percolation: The Upper Mantle as a Chromatographic Column
Oded Navon,Edward M. Stolper +1 more
TL;DR: In this article, the authors have modeled aspects of these chemical interactions in terms of fraction exchange processes similar to those operating in simple chromatographic columns and found that the composition of melt emerging from the top of a column gradually evolves from close to the incipient melt of the column matrix toward that of the melt introduced into the base of column.
