Journal of Metamorphic Geology, Volume 43, Issue 3, Page 257-285, April 2025.ABSTRACT Exhumed high‐P/low‐T complexes are of paramount importance to directly access rocks that experienced subduction zone processes. However, the original tectono‐metamorphic fabrics are often partially obliterated by exhumation and later deformation, hindering our understanding of the processes occurring at depth.

Reaction-induced rheological weakening enables oceanic plate subduction
Nature Communications, 2016 Plate subduction initiation requires weak boundaries between tectonic plates, but how weaknesses develop is unclear. Here, using high-pressure friction experiments on peridotite gouge material, the authors show that hydration reactions contribute to the ...

Systematic Entomology, Volume 50, Issue 2, Page 269-295, April 2025.We describe Kanakinthus koniambo, a new genus and species of the subtribe Lebinthina endemic to New Caledonia using ultrasonic calls, and three new species of the genus Agnothecous. We provide a robust dated phylogeny of the subfamily Eneopterinae using eight molecular markers and a comprehensive taxon sampling with a focus on the Western Pacific ...

How Cratonic Roots Survive With Weak Mid‐Lithosphere Discontinuities
Geophysical Research Letters, Volume 52, Issue 6, 28 March 2025.Abstract The stability of cratons has long been attributed to their neutral buoyancy and strong roots. However, recent seismic studies have revealed widespread mid‐lithospheric discontinuities (MLDs) within cratonic roots. Previous studies, based on geophysical and xenolith evidence, mainly suggest that MLDs are formed through metamorphic processes and

Geophysical Research Letters, Volume 52, Issue 6, 28 March 2025.Abstract The southern Mariana subduction zone, home to the Challenger Deep—the deepest known point on Earth—poses significant challenges for studying the hydration of the subducting plate due to its extreme depth. This study uses S‐wave seismic tomography and Vp/Vs ratios to investigate hydration and serpentinization at the Challenger Deep.
