Ni laterites are considered worthy targets for critical metals (CM) exploration as Rare Earth
Elements (REE), Sc and platinum group elements (PGE) can be concentrated during …

Mantle peridotites of ophiolites have traditionally been interpreted as fragments of residual
oceanic lithospheric mantle depleted by partial melting. However, recent petrological …

Where ultramafic rocks are exposed to water at temperatures< 400° C, they inevitably
undergo serpentinization reactions to form serpentine±brucite±talc±magnetite (in addition to …

Serpentinization of mantle peridotite generates molecular hydrogen that can be exploited by
microorganisms to gain metabolic energy; however, the mechanisms that control hydrogen …

Whereas the serpentinization reaction leads to stark differences in the physical properties of
mantle rocks at mid-ocean ridges, the chemical changes associated with this reaction are …

Previous studies have concluded that dehydration of serpentinites in subduction zones
produces oxidizing fluids that are the cause of oxidized arc magmas. Here, observations of …

Serpentinites are an important component of the oceanic lithosphere that formed at slow to
ultra-slow spreading centers. Serpentine could thus be one of the most abundant hydrous …

Abstract The Cerro del Almirez massif (Spain) represents a unique fragment of serpentinized
oceanic lithosphere that has been first equilibrated in the antigorite stability field (Atg …

The hydrous alteration of ultramafic rocks, known as serpentinization, generates fluids that
can fuel microbial communities and enable the synthesis of simple organic compounds …

Abstract Wasilewski et al.(1979) concluded that no magnetic remanence existed in the
uppermost mantle and that even if present, such sources would be at temperatures too high …
