Clinopyroxene major and trace element compositions document their physicochemical evolution and have been widely used to detect mantle metasomatism. Classical methods typically rely on one or several elemental ratios such as Ca/Al, Mg/Fe, La/Yb, and Ti ...

Evidence of metasomatism in the interior of Vesta
Nature Communications, 2020 Diogenites 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)

To test the ability of Mg and Zn isotopes in discriminating between different types of mantle metasomatism and identifying deep carbon cycling, here we present a comparative study on two types of Cenozoic lavas in SE Tibet, that is, K‐rich (potassic ...

Subduction, mantle metasomatism, and gold: A dynamic and genetic conjunction
GSA Bulletin, 2020Global gold deposit classes are enigmatic in relation to first-order tectonic scale, leading to controversial genetic models and exploration strategies.

Why metasomatic fronts are really metasomatic sides
Geology, 1995Back-scattered electron microscope images of metasomatic calc-silicate rocks demonstrate complex mineral growth patterns; often oscillatory zoning defines a euhedral or subhedral morphology. We infer from this the existence of an appreciable transient porosity (up to a few percent) during metasomatic calc-silicate growth, and argue that porous ...
