Corrigendum to: A Thermodynamic Model for the Subsolidus Evolution and Melting of Peridotite
We present a structural update to the thermodynamic model for calculating peridotite phase relations and melt compositions at 0·01 to 60 kbar and from 600 °C to the peridotite liquidus in the system K2O–Na2O–CaO–FeO–MgO–Al2O3–SiO2–TiO2–Fe2O3–Cr2O3 ...

Atomic structure and physical properties of peridotite glasses at 1 bar
Earth’s mantle, whose bulk composition is broadly peridotitic, likely experienced periods of extensive melting in its early history that formed magma oceans and led to its differentiation and formation of an atmosphere. However, the physical behaviour of

Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Ophiolite-hosted diamond from peridotites and podiform chromitites significantly differs from those of kimberlitic diamond and ultra-high pressure (UHP) metamorphic diamond in terms of occurrence, mineral inclusion, as well as carbon and nitrogen ...

Orthopyroxene was analyzed as a proxy for water supra‐subduction‐zone peridotite by polarized infrared radiation. Samples from Conical and Torishima seamounts, Mariana‐Izu‐Bonin forearc (ODP‐Leg 125), have very similar average H2O contents of 215 ppm ...

Braided peridotite sills and metasomatism in the Rum Layered Suite, Scotland [PDF]
The Rum Eastern Layered Intrusion (ELI; Scotland) is an open-system layered intrusion constructed of 16 macro-rhythmic units. Each of the macro-rhythmic units consists of a peridotite base and a troctolite (+/- gabbro) top, previously attributed to the ...

Arc-like magmas generated by mélange-peridotite interaction in the mantle wedge
The mechanisms of transfer of crustal material from the subducting slab to the overlying mantle wedge are still debated. Mélange rocks, formed by mixing of sediments, oceanic crust, and ultramafics along the slab-mantle interface, are predicted to ascend
