High-pressure COH fluids have a fundamental role in a variety of geological processes.
Their composition in terms of volatile species can control the solidus temperature and …

Forsterite (Fo)-rich olivine compositions from San Carlos (Arizona, SW USA) are commonly
used as starting material in experimental petrology. In comparison to the San Carlos …

Reaction between mid‐ocean ridge basalt (MORB) and crystal mush in the lower oceanic
crust has been invoked to explain chemical variations of both MORB and minerals in the …

Magma migration and differentiation processes are key to understanding the development
and evolution of oceanic magma reservoirs. To provide new quantitative geochemical …

Many recent studies have investigated the replacive formation of troctolites from mantle
protoliths and the compositional evolution of the percolating melt during melt–rock …

Melt-mineral interactions may strongly affect the mineralogy and chemistry of the upper
mantle. Although the grain-scale processes governing the interaction have been …

Although seismic and hydrothermal data show evidence of magma–seawater interaction in
slow spreading-rate ridges, such a process has been rarely observed in situ in lower …

The building of oceanic crust at Oceanic Core Complexes (OCC) has been described as a
complex process involving multiple intrusions of magma over a protracted period of time …

Pyroxenites are diffuse in fertile mantle peridotites and considered an important component
in the mantle source of oceanic basalts. They are rarely documented in abyssal and …

The new mckelveyite group mineral alicewilsonite-(YCe), ideally Na 2 Sr 2 YCe (CO 3) 6⋅
3H 2 O, was found at Mont Saint-Hilaire, Quebec, Canada, and subsequently at the Saint …
