Seismic evidence for uniform crustal accretion along slow-spreading ridges in the equatorial Atlantic Ocean

Z Wang, SC Singh - Nature Communications, 2022 - nature.com
The crustal accretion along mid-ocean ridges is known to be spreading-rate dependent.
Along fast-spreading ridges, two-dimensional sheet-like mantle upwelling creates relatively …

Lesser Antilles slab reconstruction reveals lateral slab transport under the Caribbean since 50 Ma

YW Chen, J Wu, S Goes - Earth and Planetary Science Letters, 2024 - Elsevier
The link between surface tectonic plates and mantle slabs is fundamental for paleo-tectonic
reconstructions and for our understanding of mantle dynamics. Many seismic tomography …

A seismic tomography, gravity, and flexure study of the crust and upper mantle structure of the Hawaiian Ridge: 1

BG MacGregor, RA Dunn, AB Watts… - Journal of …, 2023 - Wiley Online Library
Abstract The Hawaiian Ridge has long been a focus site for studying lithospheric flexure due
to intraplate volcano loading, but crucial load and flexure details remain unclear. We …
