Investigating the Antarctic Lithosphere Through Sp Receiver Function Analysis
Geochemistry, Geophysics, GeosystemsTo better understand the lithosphere of Antarctica, we imaged its lithosphere‐asthenosphere boundary (LAB) and crust‐mantle transition using Sp receiver functions from teleseismic events analyzed at individual stations and with common conversion point ...

Influence of Inherited Rifted Margin Architecture on Continental Collision Dynamics
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.Abstract Continental collision is a key process in lithospheric evolution, driving mountain building, crustal thickening, and supercontinent assembly. Within the Wilson cycle, collision marks the final stage following rifting, ocean spreading, and subduction.

Tertiary-Quaternary subduction processes and related magmatism in the Alpine-Mediterranean region [PDF]
, 2006 During Tertiary to Quaternary times, convergence between Eurasia and Africa resulted in a variety of collisional orogens and different styles of subduction in the Alpine-Mediterranean region.

Key New Evidence for the Hainan Mantle Plume Head: Ongoing Formation of a Large Igneous Province?
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.Abstract The process‐based surface magmatic expression of mantle plumes is typically a large igneous province (LIP) induced by the mantle plume head, followed by subsequent age‐progressive volcanic tracks resulting from plate drifting above the plume tail.

Plug flow in the Earth's asthenosphere
Earth and Planetary Science Letters, 2017 Recent seismic observations, focused on mantle flow below the Pacific plate, indicate the presence of two shear layers in the Earth's asthenosphere. This is difficult to explain under the classic assumption of asthenosphere flow driven by plate shear ...

Computation of a combined spherical-elastic and viscous-half-space earth model for ice sheet simulation [PDF]
, 2006 This report starts by describing the continuum model used by Lingle & Clark (1985) to approximate the deformation of the earth under changing ice sheet and ocean loads.

The Influence of Fluvial Incision on the Lithospheric Stress Field: A Numerical Approach
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.Abstract Erosion along large fluvial valleys transports important sedimentary volumes across continents over geological time, modifying the loads imposed on the lithosphere and inducing isostasy‐related subsurface stresses. This work presents numerical experiments with a visco‐plastic lithosphere aimed at understanding the distribution and evolution of

Natural evidence for garnet-spinel transition (GST) in the Earth's mantle [PDF]
, 2008 This study based on compiled world-wide garnet peridotite data confirms the GST in high P and T conditions, which was obtained from Al-free experimental system (MgO-Cr~2~O~3~-SiO~2~) by Klemme (2004). A new spinel-phase peridotite zone, garnet peridotite

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.Abstract The 2021–2023 OHANA ocean‐bottom seismometer deployment in the northeast Pacific Ocean provides a rich data set for seismic studies to explore the crust, lithosphere and asthenosphere in a 600 km wide region about 1,500 km northeast of Hawaii, west of the Moonless Mountains. The study area covers mainly 40‐to‐55 Myr‐old Pacific lithosphere.
