Dating C/S Structures in Syntectonic Granites by In Situ Rb‐Sr Analyses on Muscovite

Terra Nova, Volume 38, Issue 2, Page 124-129, April 2026.
ABSTRACT The interplay of crystallisation, deformation and fluid–rock interactions makes deciphering geochronological information complex in syntectonic granites. In this study, we apply in situ Rb‐Sr analyses to selected samples from the Questembert Variscan syntectonic granite in Western France, which was emplaced along the South Armorican Shear Zone

Differing Controls on the Cycling of Neodymium in the Atlantic and the Pacific

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Neodymium (Nd) isotopes ratios are regarded as a key proxy for past ocean circulation despite unsettled debate on marine Nd cycle controls, which opposes a “top‐down” hypothesis (surface sources dominate) and a “bottom‐up” hypothesis (sedimentary sources dominate), each with important implications for Nd isotope proxy interpretation.

Splay Fault Permeability Governs Fluid–Structure Interaction in Accretionary Wedges

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Interactions between upper plate deformation and plate interface seismicity in subduction zones remain poorly understood, but growing evidence indicates that fluid flow along splay faults modulates upper‐plate faulting. Field observations from two exhumed splay faults define end‐member scenarios where impermeable faults trap fluids in their ...

A Curie Point Depth Model of the Conterminous United States Derived From a Prior‐Constrained Equivalent Source Inversion

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract The Curie Point Depth (CPD) is a key thermal boundary in the deep lithosphere and is widely used to constrain its thermal structure. However, uncertainties in magnetization and the non‐uniqueness of inversion lead to considerable inter‐study differences.

Polyurethane Cascade Depolymerization by a Combination of Thermal Pretreatment and Enzymatic Hydrolysis

ChemSusChem, Volume 19, Issue 5, 13 March 2026.
This study explored the cascade depolymerization of a polyether‐polyester polyurethane based on a combination of low‐temperature thermal treatment and enzymatic hydrolysis. Heat pretreatment changed the physicochemical properties of polyurethane, followed by cutinase‐catalyzed hydrolysis, leading to an increase in weight loss and the production of two ...
