Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.Abstract Modeling processes within Earth's and other planetary bodies' mantle requires constraints from phase equilibrium to infer how changes in phase abundance and composition affect physical properties and geochemical processes. When applying such thermodynamic models on a planetary scale, performance becomes especially crucial.

Towards improving the single grain clinopyroxene geobarometer for garnet peridotites
, 2023 Exploration methods for diamonds often employ the geochemistry of single minerals to identify deposits. Due to the scarcity of diamonds, exploration practices use minerals known as “kimberlite indicator minerals” as these minerals are typically more ...

The Lages diatremes: mineral composition and petrological implications
Anais da Academia Brasileira de Ciências, 2007 Chemical data of heavy minerals from Lages diatremes in southern Brazil have been studied with the aim of characterizing the sample source(s). Three groups of minerals are recognized: I) aluminian-chromian pyroxene, pyrope garnet and chromian spinel ...

Mineral chemistry, thermobarometry and tectonomagmatic setting of Late-Cretaceous volcanic rocks from the Kojid area (south of Lahijan, northern Alborz) [PDF]
پترولوژی, 2018 The volcanic rocks of Kojid area (south of Lahijan) crop out in northern Alborz. They show mainly pillow structure with numerous cross-cutting dykes. Based on lithostratigraphic relationships and interpillow pelagic limestones, the volcanics are Late ...

The Role of Chlorate‐Driven Oxidative Weathering in Shaping Clay Deposits on Mars
Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.Abstract Oxidized clays and the widespread Al/Si‐over‐Fe/Mg stratigraphy on Mars imply prolonged water‐rock interactions and efficient oxidative weathering despite the largely anoxic conditions of Early Mars when most deposits formed during the climate optimum.

FLUORINE PARTITIONING BETWEEN QUADRILATERAL CLINOPYROXENES AND MELT
Geological Society of America Abstracts with Programs, 2020 Abstract Concentrations of fluorine and chlorine were measured in glasses (quenched melts) and coexisting clinopyroxene, orthopyroxene, olivine, and plagioclase in run products of experiments previously used to measure sulfur partitioning between these phases.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.Abstract Oceanic Core Complexes (OCCs) in back‐arc basins are not as thoroughly investigated, and their termination processes remain poorly understood. The Godzilla Megamullion is the largest known ceased OCC on Earth, yet magmatic and hydrothermal records from its termination are lacking.
