Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.Abstract Chlorite is thought to be one of the major water‐carrying phases in subduction zones, both within the slab and in the mantle wedge. Its presence has previously been linked to common seismological observations at subduction zones, including P and S wave anisotropy as well as high VP/VS ratios (>1.8) in the mantle wedge.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.Abstract Oceanic lithosphere is continuously destroyed by subduction, challenging our ability to develop tectonic reconstructions. One way to tackle this problem is to examine relics of once‐consumed oceanic domains preserved along convergent margins. In the New England Orogen (eastern Australia), disrupted exposures of ultramafic rocks loosely define ...

Investigating Layered Cratonic Lithosphere in the Fennoscandian Shield
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.Abstract Cold, thick, and chemically depleted lithosphere with high seismic velocity and low attenuation characterizes continental cratons. However, discrepancies between xenolith‐based thermal constraints and those inferred from surface‐wave seismic models, together with the widespread observation of mid‐lithosphere discontinuities, challenge the ...

Boletín Geológico, 2020 The products of metasomatic alteration (e.g., carbonation) of peridotites are called listvenites. Based on a description of the outcrops in the laterite deposit at Cerro Matoso located in the NW of Colombia, the mineralogical composition confirmed by ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.Abstract This commentary concerns a two‐part paper by Regenauer‐Lieb et al. (2026a, 2026b) on pattern formation in deforming porous rocks. The theory developed in part I (https://doi.org/10.1029/2025GC012710) uses the general idea of Turing's reaction‐diffusion model of morphogenesis based on interactions between two types of diffusible chemical ...

Nibble metasomatic K-feldspathization [PDF]
, 2003 Nibble metasomatic K-feldspathization intensively occurred in undeformed Huangnitian hornblende quartz syenite. The main replaced mineral is the widely distributed primary K-feldspar. Nibble replacing K-feldspar occurs on the grain boundaries between two

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.Abstract Characterizing products of water‐rock interactions in low‐temperature serpentinization of ultramafic rock is key to reconstructing fluid alteration histories of the crust and identifying subsurface habitable environments. We analyzed terrestrial peridotites from the Samail ophiolite using visible to near‐infrared (VNIR‐SWIR) microimaging ...
