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.

Diachronous Accumulation of Mid‐Pleistocene Gravel Beds Driven by Tectonics Across the Tibetan Plateau

Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.
Abstract Deciphering how the widespread late Cenozoic conglomerates were formed across the Tibetan Plateau is crucial for understanding the competition between tectonics and climate. Here we target the mid‐Pleistocene conglomerate cap along the northern Saishiteng range (SR), North Tibet. 26Al/10Be burial dating constrains the onset accumulation of the

Climate Control on Erosion: Evolution of Sediment Flux From Mountainous Catchments During a Global Warming Event, PETM, Southern Pyrenees, Spain

Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.
Abstract Extreme hydroclimates impact sediment fluxes from mountainous catchments to the oceans. Given modern global warming, a challenge is to assess the sensitivity of erosion in mountainous catchments to extreme climate perturbations. Here, we reconstruct paleo‐sedimentary fluxes across an abrupt global warming, the Paleocene‐Eocene Thermal Maximum (

The Impact of Mélange Formation on the Rheology and H2O Budget of the Subduction Zone Interface, With Implications for Diapir Nucleation

Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.
Abstract At the subduction zone interface, a combination of mechanical deformation and (fluid‐mediated) chemical mixing of oceanic crust, sediment and mantle lithologies yields heterogeneous mélange lithologies. These mélanges have compositions and metamorphic mineral assemblages dissimilar to their endmember source lithologies, resulting in a ...
