Multi‐Stage Growth of Kyanite in Migmatites Interpreted by Integrating Forward Thermodynamic Modelling and Trace Element Signature

open access: yesJournal of Metamorphic Geology, Volume 43, Issue 4, Page 315-339, May 2025.
ABSTRACT Trace element zoning in kyanite can retain information about its growth history, particularly in anatectic metapelites. There, kyanite can grow (i) at sub‐solidus conditions through metamorphic reactions involving other aluminous phases as reactants, (ii) through muscovite dehydration melting reactions, and (iii) during cooling and melt ...

Melt–Rock Interaction Experiments Reveal Rapid Microstructural and Chemical Changes at Lower Crustal Conditions

open access: yesJournal of Metamorphic Geology, Volume 43, Issue 4, Page 341-358, May 2025.
ABSTRACT The reactive flow of melt through the mantle or crust triggers chemical disequilibrium, driving reactions that significantly alter the mineral assemblages and physical properties of host rocks. However, the degrees of chemical difference required to initiate these reactions and their timescale remain poorly understood.

Seismological Constraint of the Fossil Suture Zone: A Case Study in the Eastern Central Asian Orogenic Belt

open access: yesGeophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract The tectonic attributes of the fossil suture zone are crucial for reconstructing tectonic evolution, but they remain contentious due to inadequate crustal constraints. This study introduces a high‐resolution crustal structure derived from a cost‐effective short‐period dense seismic array across fossil suture zones between the Xing'an and the ...
