Journal of Metamorphic Geology, Volume 43, Issue 7, Page 663-680, September 2025.ABSTRACT The youngest known ultrahigh‐pressure (UHP) eclogite from Tumagabuna Island, a small island of the D'Entrecasteaux Islands chain in Papua New Guinea, exhibits zircon U–Pb age variations spanning a few million years. This age variation complicates the interpretation of the evolution of this high and ultrahigh‐pressure ([U]HP) terrane.

Rare alkali metals in micas from Shakhdarinskaya miarolitic pegmatite (South-Western Pamir)
Известия Томского политехнического университета: Инжиниринг георесурсов, 2017 The study is focused on the mineralogy of rare-element rich tourmaline-bearing miarolitic pegmatities of the Shakhdarinskaya vein (SW Pamirs, Tajikistan). The results of the study are crucially important for understanding the regularities of distribution and behavior of Li, Rb and Cs in the course of crystallization of the most low-temperature ...

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 6, June 2025.Abstract A striking feature of the Imilchil alkaline province, in the Moroccan Central High Atlas, is the close association of magmatic intrusions with Triassic sediments exhumed by diapirism. This study reports field, petrographic, geochemical and Sr‐Nd isotopic data, as well as new U‐Pb zircon ages, which allow us to constrain the timing of the ...

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 3, March 2025.Abstract Stable and inert under most conditions, zircon can be dissolved and precipitated by aqueous fluids in the upper crust. Geochemical models using currently available thermodynamic properties for Zr aqueous species at 0.2 GPa predict that zircon solubility increases with temperature from 400 to 900°C in fluids saturated with quartz or baddeleyite.

Electrochemical recycling of lithium‐ion batteries: Advancements and future directions
EcoMat, Volume 6, Issue 11, November 2024.This review examines lithium‐ion batteries associated with the global energy transition, particularly for use in electric vehicles and renewable energy‐storage systems. It addresses environmental concerns and resource scarcity, emphasizing the need for sustainable recycling strategies. Various recycling methods, in particular electrochemical techniques,

Journal of Metamorphic Geology, Volume 42, Issue 7, Page 933-956, September 2024.Abstract Recent studies of the Cretaceous lower arc crust exposed in Fiordland, New Zealand, conclude that shear zones are sites of melt migration and mass transfer through the deep crust. Here, we investigate the 4–10 km‐wide George Sound Shear Zone, which cuts the Western Fiordland Orthogneiss, comprising two main rock types: two‐pyroxene gneiss and ...

Geological Journal, Volume 59, Issue 8, Page 2190-2207, August 2024.U–Pb ages, and O–Hf isotopic compositions of inherited and synmagmatic zircons are addressed to trace the source rocks and petrogenesis of a monzogranite pluton, which belong to the flare‐up of granitoids at 465–445 Ma in the South Altyn Tagh. The observations indicate that this monzogranite is mainly derived from reworking of exhumed continental crust,

Geophysical Research Letters, Volume 51, Issue 13, 16 July 2024.Abstract Continental alkaline magmatism has been suggested to play a significant role in releasing deep mantle carbon into the atmosphere, which can greatly impact the global climate. However, the temporal variations of alkaline magmatism and their potential to modulate climate over geologic time remain poorly constrained. The detrital zircon record is
