A Mechanistic Look at the Amphibolitization of Mafic Crust: Insights From the Kråkeneset Gabbro Body, Western Gneiss Region, Norway

Journal of Metamorphic Geology, Volume 43, Issue 4, Page 385-405, May 2025.
ABSTRACT Fluid–rock interactions play a key role in the formation, evolution and recycling of the Earth's crust. For fluids to infiltrate rocks and enable and sustain fluid‐mediated mineral transformations, fluid pathways are required. In this study, we examined the potential mechanisms of formation of such pathways via detailed mineralogical ...

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 ...

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

Journal 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.

A New UHP‐HP Tectono‐Metamorphic Architecture for the Southern Dora‐Maira Massif Nappe Stack (Western Alps) Based on Petrological and Microstructural Evidence

Journal of Metamorphic Geology, Volume 43, Issue 4, Page 359-383, May 2025.
ABSTRACT The southern Dora‐Maira Massif, where coesite was first discovered 40 years ago, is among the most studied and better known example of high/ultra‐high‐pressure (HP/UHP) terranes. Previous to this study, the Polymetamorphic Basement Complex of the southern Dora‐Maira Massif has been defined as a nappe stack consisting of three juxtaposed ...

Equilibrium Silicon Isotope Fractionation in Eclogites and Granites Constrained by Single Crystal X‐Ray Diffraction and the Force Constants Approach

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract Using our recently developed X‐ray diffraction based force constants approach, we have determined the equilibrium Si isotope fractionation between omphacite/garnet, quartz/kyanite, and quartz/zircon at temperatures relevant to the petrogenesis. We find that Na strongly affects the Si isotope fractionation between omphacite and garnet.
