Clinopyroxene Dissolution Records Rapid Magma Ascent [PDF]
Frontiers in Earth Science, 2020 Magma ascent rates control volcanic eruption styles. However, the rates at which basaltic magmas ascend through the crust remain highly uncertain. Although recent studies have successfully exploited records of decompression driven degassing to estimate ...

Nanoscale solid-fluid interaction and amphibole formation in the lithospheric mantle [PDF]
Scientific ReportsNanoscale amphibole nucleation and growth in the Earth’s mantle is poorly understood despite its important role in the evolution and stability of the lithosphere, along with its influence on the coexisting fluid composition.

Circular Potential of Lithium-Ion Battery Recycling Slags: Quantifying Microstructure and Elemental Distribution for a Holistic Valorization. [PDF]
Adv Sci (Weinh)A lithium‐bearing slag is investigated with the goal of holistic valorization. The present β‐eucryptite (LiAlSiO4) exhibits a high lithium content and low levels of impurities. The spinel contains most of the chromium and vanadium, representing additional valorization opportunities.

Compositional Data Analysis (CoDA) of Clinopyroxene From Abyssal Peridotites
Geochemistry, Geophysics, Geosystems, 2022 We analyze a large database of abyssal peridotite clinopyroxene compositions using log‐ratio transformation, principal component analysis (PCA) and k‐means clustering, to better understand clinopyroxene compositional systematics in abyssal peridotites ...

PHYSICO-CHEMICAL CONDITIONS OF CRYSTALLIZATION OF MINERALS-PHENOCRYSTS IN BASALTIC COMPLEXES HOSTING MASSIVE SULFIDE DEPOSITS OF THE URALS AND SIBERIA [PDF]
Минералогия, 2020 The paper discusses the physico-chemical formation conditions of minerals-phenocrysts in basaltic complexes, which host massive sulfide deposits of the Urals and Siberia. It is found as a result of study of melt inclusions that clinopyroxene from basalts
