[HTML][HTML] Interactions of magmas and highly reduced fluids during intraplate volcanism, Mt Carmel, Israel: Implications for mantle redox states and global carbon cycles
Oxygen fugacity (ƒO 2) controls the speciation of COH fluids in Earth's mantle; a major
question is whether the sublithospheric mantle is metal-saturated, maintaining ƒO 2 near the …

Vestiges of early Earth's deep subduction and CHONSP cycle recorded in Archean ophiolitic podiform chromitites
Ophiolitic podiform chromitites from Phanerozoic orogens have been shown to preserve a
wealth of textures and inclusions that, in some way, trace earlier episodes of subduction and …

In situ peridotitic diamond in Indus ophiolite sourced from hydrocarbon fluids in the mantle transition zone
In recent years ophiolitic diamonds have been reported mostly from podiform chromitites.
However, the mechanism of such diamond formation remains unknown. We report in situ …

First terrestrial occurrence of tistarite (Ti2O3): Ultra-low oxygen fugacity in the upper mantle beneath Mount Carmel, Israel
The minimum oxygen fugacity (f O2) of Earth's upper mantle probably is controlled by metal
saturation, as defined by the iron-wüstite (IW) buffer reaction (FeO→ Fe+ O). However, the …
