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

Journal 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 ...

Stability of Reactive Iron‐Bound Organic Carbon During Sulfidization of Iron Oxides: Insights From Methane‐Seep Sediments

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract The association of organic carbon (OC) to reactive iron oxides (FeR), forming OC‐FeR complexes, represents a significant OC sink in marine sediments. However, the impact of diagenetic processes, such as sulfate reduction and iron sulfide formation, on the stability of OC‐FeR in marine sediments remains poorly understood.

Was the Lhasa Block at Low Latitudes in the Middle Permian? Insights From New Paleomagnetic and Geochronological Data

Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.
Abstract The absence of reliable paleomagnetic constraints from the Lhasa Block has led to alternative interpretations of its late Paleozoic position and timing of rifting from Gondwana, reflecting uncertainties in early Neo‐Tethyan paleogeography. This study presents paleomagnetic and geochronological data from the middle Permian Luobadui Formation ...
