Chronology and Genesis of Fine-grained Granite in the Southern Area of Le’an, Central Jiangxi

open access: yesDonghua Ligong Daxue Xuebao. Ziran Kexue Ban
[Objective] This study investigates the petrogenesis and tectonic setting of fine-grained granites exposed in the southern Le'an area. Determining the origin and emplacement environment of these granites is important for understanding regional magmatic ...

BaSIC: A Bayesian Inversion Model for Basalt Source Investigation and Characterization

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract We present BaSIC: Basalt Source Investigation and Characterization, an open‐source Python based Bayesian inversion method to constrain the source mineralogy of basalts. Using bulk rock geochemistry, the model takes the averages and standard deviations of six elemental ratios (Mn/Fe, Zn/Fe, Mn/Zn, Sc/Zn, Co/Fe, and Ga/Sc) for a given basalt ...

Experimental Shock Metamorphism of Zircon, Apatite, and Whitlockite From 5 to 40 GPa

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Hypervelocity impacts modify planetary crusts and can alter the microstructures of key minerals used to reconstruct planetary histories. We investigated the potential effects of impacts on three common accessory minerals found in terrestrial crusts by experimentally shocking zircon, apatite, and whitlockite at 5, 10, 20, and 40 GPa.

Revisiting olivine‐phyric shergottites: Pyroxene crystallization pressure and the role of undercooling

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 10, Page 2466-2475, October 2026.
Abstract Shergottites are the most abundant meteorites from Mars and a major source of information on magma reservoirs, transport, and eruption, particularly in the late Hesperian northern hemisphere. Conflicting interpretations have arisen on the crystallization conditions of pyroxene in olivine‐phyric shergottites.

Deep Crustal Magma‐Water Interaction During Oceanic Core Complex Termination of the Godzilla Megamullion in the Parece Vela Basin

open access: yesGeochemistry, 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.
