Cobalt-based pyroxenes: A new playground for Kitaev physics Journal: Proceedings of the National Academy of Sciences of the United States of America Published: 2024-10-22 DOI: 10.1073/pnas.2409154121 ...

Magnesium-bearing pyroxenes typically occur in basic rocks and meteorites and the crystallization history can be partly deduced from crystallographic relics consequent on phase inversion.

Because many groups contain cases from both kimberlite and xenoliths, some kimberlite pyroxenes may derive from fragmented xenoliths. However from size alone, large discrete orthopyroxene crystals, ...

Pyroxenes are a major group of rock-forming minerals. Scientists investigated the iron ion status of a calcium-rich pyroxene, using Mössbauer spectroscopy on thin sections of single crystals.

The ignimbrite (Ig) is divided into chronologically and/or geographically distinct packages of material. Earlier packages (Ig1) were emplaced mostly eastward, are wholly intraplinian (coeval with fall ...

Given their abundance, elucidating the physical properties of pyroxenes is deemed vital in the study of rocks and minerals. Monoclinic pyroxenes, specifically, are a type of calcium-rich pyroxenes.
