Mantle Flow Drives the Subsidence of Oceanic Plates [PDF]
Science, 2010 Sinking Sea Floors The depths of ocean bottoms are constantly fluctuating at a very slow rate in response to the generation (at mid-ocean ridges) and consumption (at subduction zones) of sea-floor material. Because older sea floor is susceptible to sinking as it cools, it has been assumed that sea-floor depth varies directly with

Geophysical Research Letters, 2021 Heat flow measurements are important for our understanding of planetary interior composition, structure, and evolution. In the absence of direct measurement, a first‐order estimate of a planet's interior heat flow can be made by modeling the lithosphere ...

The deep Earth origin of the Iceland plume and its effects on regional surface uplift and subsidence [PDF]
Solid Earth, 2017 The present-day seismic structure of the mantle under the North Atlantic Ocean indicates that the Iceland hotspot represents the surface expression of a deep mantle plume, which is thought to have erupted in the North Atlantic domain during the ...

Mantle Flow Pattern Associated With the Patagonian Slab Window Determined From Azimuthal Anisotropy
Geophysical Research Letters, 2022 Geological processes in Southern Patagonia are affected by the Patagonian slab window, formed by the subduction of the Chile Ridge and subsequent northward migration of the Chile Triple Junction.

Multidisciplinary Constraints on the Thermal‐Chemical Boundary Between Earth's Core and Mantle
Geochemistry, Geophysics, Geosystems, 2022 Heat flux from the core to the mantle provides driving energy for mantle convection thus powering plate tectonics, and contributes a significant fraction of the geothermal heat budget.

Joint Interpretation Results of Gravitational and Thermal Fields for the Ural Region
Russian Journal of Earth Sciences, 2023 A method for solving conjugation problems for the Poisson equation is implemented, which makes it possible to interpret potential fields (gravitational and stationary thermal fields) based on unified grid algorithms.

Seismic evidence for subduction-induced mantle flows underneath Middle America
Nature Communications, 2020 The motions of subducted slabs are expected to drive mantle flow around slab edges, however, evidence of deep mantle flow has so far remained elusive.

Upper Mantle Anisotropy and Flow Beneath the Pacific Ocean Revealed by Differential PS‐SKS Splitting
Geophysical Research Letters, 2023 Upper mantle anisotropy has been mapped beneath continents at high spatial resolution. Beneath the oceans, however, shear wave splitting constraints on upper mantle anisotropy are sparse, due to the paucity of seismic receivers. A technique that does not
