Abstract The Central European Variscides and their epicontinental basins and grabens
(Mesoeurope sensu Stille) subsided into the uplifted basement as well as the Alpidic …

Alteration of ultramafic rocks plays a major role in the production of hydrocarbons and
organic compounds via abiotic processes on Earth and beyond and contributes to the …

Estimates of dissolved CO2 in subduction-zone fluids are based on thermodynamic models,
relying on a very sparse experimental data base. Here, we present experimental data at 1–3 …

Abstract Serpentinites in the Eastern Desert of Egypt are the most distinctive lithological unit
in the Arabian–Nubian Shield (ANS) ophiolite sequence which associated with major suture …

Magnetite breakdown during subduction of serpentinised ultramafic rocks may produce
oxidised fluids that oxidise the deep Earth and/or the sub-arc mantle, either via direct …

If magnetite is a common serpentinization product, centimetric, massive and pure magnetite
veins are rarely observed in serpentinites. Unique example, in the Aït Ahmane ultramafic …

Abstract The Cogne magnetite deposit (Western Alps, Italy) is the largest in a series of
apatite and sulphide-free magnetite orebodies that are hosted in serpentinites belonging to …

Carbonated ultramafic rocks (ie, ophicarbonates) form by peridotite serpentinization and
carbonation at the seafloor. Their metamorphic evolution is linked to that of serpentinites …

The evolution of the seawater oxygen isotopic composition (δ18O) through geological time
remains controversial. Yet, the past δ18Oseawater is key to assess past seawater …

The valence of carbon is governed by the oxidation state of the host system. The subducted
oceanic lithosphere contains considerable amounts of iron so that Fe3+/Fe2+ equilibria in …
