Hydroclimatic Changes in the Marsyangdi River Basin, Central Himalaya Under CMIP6 Scenarios: Implications for the Water–Energy–Food–Ecosystem Nexus

Meteorological Applications, Volume 33, Issue 5, September/October 2026.
Under CMIP6 scenarios in the Marsyangdi River Basin, SWAT+ simulations show that warming and shifting precipitation diminish snowfall and cryospheric buffering, deepening pre‐monsoon flow deficits. This seasonal mismatch drives critical Water–Energy–Food–Ecosystem trade‐offs: dry‐season run‐of‐river hydropower generation drop, and increase in winter ...

Geophysical Investigation of a Thermal Field in Abu Dhabi, United Arab Emirates

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract In the Abu Dhabi Emirate, near Madinat Zayed and Liwa, studies have identified high geothermal gradients and high‐heat‐flow areas. Assessing the geothermal potential in this region requires a detailed mapping of subsurface geological formations and their thermal properties.

Probing the Elastic Anisotropy of Schistose Rocks West of the Tauern Window (Eastern Alps, Austria): The Largest Homogeneous Volume

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The anatomy of orogens is difficult to decipher as structural information is usually limited to surface and seismic data. Seismic properties are directionally dependent on anisotropic minerals, especially phyllosilicates. Due to tectonic complexity, the effect of anisotropy in seismic data is difficult to determine.

A rapid transition from subduction to Barrovian metamorphism: geochronology of mafic–ultramafic relicts of oceanic crust in the Central Alps, Switzerland

Swiss Journal of Geosciences
Relicts of subducted oceanic lithosphere provide key information for the tectonic reconstructions of convergent margins. In the Central Alps, such relicts occur as isolated mafic–ultramafic lenses within the migmatites of the southern Adula nappe and ...

Multi‐Stage Evolution of Subducted Oceanic Mantle: The Marlborough Ultramafic Suite (New England Orogen, Australia)

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 ...

Large megathrust earthquakes in cold mantle wedge corners under lawsonite blueschist facies

Nature Communications
Giant megathrust earthquakes typically occur above the upper-plate Moho or the 350°C isotherm in warm subduction zones. However, large earthquakes also occur within the mantle wedge corner at 35-55 km depth at cold subduction zones, such as the Kermadec,

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 ...

The Impact of Double Subduction on Plate Velocity and Euler Pole Shifts: Insights From Spherical Subduction Models

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Same‐dip double subduction (SDDS), in which two parallel slabs dip in the same direction, has been linked to accelerated plate motion in both modern and ancient convergent systems, such as the Late Cretaceous Africa–Eurasia system. Yet a systematic framework for quantifying how SDDS alters plate kinematics in a large‐scale spherical geometry ...

Evaluating Forced Versus Plume‐Induced Subduction Initiation for the Talkeetna‐Bonanza Arc System: Implications for Permo‐Triassic Paleogeography of the North American Cordillera

Tectonics, Volume 45, Issue 9, September 2026.
Abstract The mechanisms by which new subduction zones form remain highly debated. Here we use Permo‐Triassic strata to evaluate potential mechanisms for initiation of the Talkeetna‐Bonanza Arc of the northern North American Cordillera. New mapping and analysis of Permian and Upper Triassic strata on the Alaska Peninsula suggest a period of uplift ...
