New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.The Eastern Himalayan Syntaxis (EHS), which is located at the southeastern edge of the Qinghai–Xizang Plateau, is a key region for understanding mountain‐building and subduction processes. Bouguer gravity anomalies derived from the Earth Gravitational Model 2008 free‐air anomaly data following topographic corrections, were analyzed.

The Indian Plate subducting below the Tibet Plateau is tearing apart
Communications Earth & EnvironmentThe first-order configuration of the Himalayan orogen is defined by northward motion of the Indian plate, whether directly underplating Tibetan crust or subducting beneath a mantle wedge.

Earth and Space Science, Volume 13, Issue 3, March 2026.Abstract The Southern California Earthquake Center (SCEC) Community Rheology Model (CRM) comprises a three‐dimensional geologic framework model (GFM) of southern California's lithosphere, and synthetic aggregate ductile flow laws applicable to each GFM rock type under low‐strain conditions. Given temperature, volatile content, pressure, and strain rate,

Magnetic Reversals During the Deccan Volcanism: Paleomagnetic Insights From the Pachmarhi Dykes
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.Abstract The three main dyke swarms that are linked to the Deccan Continental Flood Basalts are the Nasik‐Pune, Western Coastal, and Narmada‐Satpura‐Tapi (N‐S‐T) swarms. Encompassing approximately 244 mapped basaltic dykes, mainly trending E‐W and positioned along an ancient tectonic zone, the Pachmarhi dyke swarm is situated in the eastern N‐S‐T ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.Abstract Petrological and seismic constraints suggest differential sampling depth for ultrahigh pressure (UHP) metamorphic rocks exposed in different segments of the fossil subduction zone of the Western Alps. However, the mechanisms for the observed differential exhumation remain to be understood. Here, we account for the continental margin subduction

The electrical structure of the central Pacific upper mantle constrained by the NoMelt experiment
Geochemistry, Geophysics, Geosystems, 2015 The NoMelt experiment imaged the mantle beneath 70 Ma Pacific seafloor with the aim of understanding the transition from the lithosphere to the underlying convecting asthenosphere.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.Abstract It is recognized that mantle plumes play a direct role in generating regional uplift and producing immense volumes of basaltic magmatism, both of which can influence paleoclimate. The Icelandic Plume, beneath the North Atlantic Ocean, is of particular importance due to its size and position at a significant paleoceanographic gateway.

Geochemistry, Geophysics, Geosystems, 2018 Imaging the lithosphere is key to understand mechanisms of extension as rifting progresses. Continental rifting results in a combination of mechanical stretching and thinning of the lithosphere, decompression upwelling, heating, sometimes partial melting
