Geological and geochemical aspects of the Loch Loyal Alkaline Complex, Sutherland [PDF]

open access: yes, 1974
The object of this investigation was to categorize all geological and geochemical parameters applicable to the Loch Loyal syenites and to relate these both to processes operating there and to the broader problems of alkaline rock genesis.

A thermodynamic modelling approach to predict the outcome of carbonaceous fluid metasomatism on Earth and Mars [PDF]

open access: yes, 2023
The carbon flux between the atmosphere and the geosphere is linked by a broad range of geodynamic and magmatic processes which govern the deep carbon cycles on all telluric planets, asteroids, and moons.

COH-fluid induced metasomatism of peridotites in the forearc mantle [PDF]

open access: yes, 2022
Devolatilization of subducting lithologies liberates COH-fluids. These may become partially sequestered in peridotites in the slab and the overlying forearc mantle, affecting the cycling of volatiles and fluid mobile elements in subduction zones. Here we

Identifying mantle carbonatite metasomatism through Os-Sr-Mg isotopes in Tibetan ultrapotassic rocks [PDF]

open access: yes, 2015
Mantle-derived magmas at convergent plate boundaries provide unique insights into the nature of materials subducted to and recycled from depths. Here we present a study of Os–Sr–Mg isotopes on the Oligocene–Miocene ultrapotassic rocks aimed at better ...

Braided peridotite sills and metasomatism in the Rum Layered Suite, Scotland [PDF]

open access: yes, 2020
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 ...

Evidence of metasomatism in the interior of Vesta [PDF]

open access: yesNature Communications, 2020
AbstractDiogenites are a group of meteorites that are derived from the interior of the largest protoplanet Vesta. They provide a unique opportunity to understanding together the internal structure and dynamic evolution of this protoplanet. Northwest Africa (NWA) 8321 was suggested to be an unbrecciated noritic diogenite meteorite, which is confirmed by
