Crustal deformation, the earthquake cycle, and models of viscoelastic flow in the asthenosphere [PDF]

The crustal deformation patterns associated with the earthquake cycle can depend strongly on the rheological properties of subcrustal material. Substantial deviations from the simple patterns for a uniformly elastic earth are expected when viscoelastic ...

Quantitative Assessment of Peridotite Tectonomagmatic Affinities Using Compositional Data Analysis and Explainable Machine Learning

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract Peridotites record the compositional evolution of the lithospheric and asthenospheric mantle across plume‐related lithospheres, convergent margins, and rift‐related volcanic environments; however, their tectonomagmatic affinities are commonly difficult to resolve using traditional low‐dimensional geochemical discrimination diagrams.

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.

Textbook Question Answering with Multi-modal Context Graph Understanding and Self-supervised Open-set Comprehension

, 2019
In this work, we introduce a novel algorithm for solving the textbook question answering (TQA) task which describes more realistic QA problems compared to other recent tasks. We mainly focus on two related issues with analysis of the TQA dataset.

Chemical Geodynamics of Granitoid Magmatism During a Pacific‐Philippine Sea Plate Transition in Southwest Japan

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract Granitoid magmatism along the western Pacific margin records interactions between subduction dynamics and crust–mantle processes; however, the links between plate reorganization and magma‐source evolution remain debated. Here we integrate U–Pb zircon geochronology with Pb–Sr–Nd–Hf isotope systematics to investigate Cretaceous–Paleogene ...

Layered Seismic Anisotropy and Tectonics of the Anatolian Plate

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Anatolian tectonics are associated with slab retreat in the west and gravitational potential energy and continental collision in the east, leading to westward motion of Anatolia relative to Eurasia, partially accommodated on the North and East Anatolian transform faults.

Satellite tidal magnetic signals constrain oceanic lithosphere-asthenosphere boundary

Science Advances, 2016
Researchers present results on the oceanic upper mantle electrical structure revealed by satellite-detected tidal magnetic signals. The tidal flow of electrically conductive oceans through the geomagnetic field results in the generation of secondary ...

Lithosphere-asthenosphere system in shield areas of North America and Europe

Annals of Geophysics, 1997
In previous papers surface dispersion data have been combined with the results of deep seismic refraction data to derive a regionalization of the lithosphere-asthenosphere system and to investigate the presence of significant heterogeneity down to depths

Oceanic lithosphere and asthenosphere: The thermal and mechanical structure [PDF]

A coupled thermal and mechanical solid state model of the oceanic lithosphere and asthenosphere is presented. The model includes vertical conduction of heat with a temperature dependent thermal conductivity, horizontal and vertical advection of heat ...
