Hotspot swells revisited
The first attempts to quantify the width and height of hotspot swells were made more than 30
years ago. Since that time, topography, ocean-floor age, and sediment thickness datasets …

Chemical geodynamics insights from a machine learning approach
The radiogenic isotope heterogeneity of oceanic basalts is often assessed using 2D isotope
ratio diagrams. But because the underlying data are at least six dimensional (87Sr/86Sr …

Control of high oceanic features and subduction channel on earthquake ruptures along the Chile–Peru subduction zone
E Contreras-Reyes, D Carrizo - Physics of the Earth and Planetary Interiors, 2011 - Elsevier
We discuss the earthquake rupture behavior along the Chile–Peru subduction zone in terms
of the buoyancy of the subducting high oceanic features (HOF's), and the effect of the …

Scoring hotspots: The plume and plate paradigms
DL Anderson - Special Papers-Geological Society of America, 2005 - books.google.com
The origin of midplate and along-ridge melting anomalies is controversial. Hypotheses
involve, at one extreme, concentrated hot mantle upwellings from the deepest mantle and, at …

Mid-Cretaceous Wake seamounts in NW Pacific originate from secondary mantle plumes with Arago hotspot composition
The geochemistry of oceanic intraplate (primarily oceanic island and seamount) lavas can
provide essential information on the composition and evolution of their mantle source and …

The crustal structure of the Cocos ridge off Costa Rica
CHE Walther - Journal of Geophysical Research: Solid Earth, 2003 - Wiley Online Library
The submarine Cocos ridge in the northwestern Panamá basin, a bathymetric feature more
than 1000‐km long and 250–500 km broad, is about 2 km shallower than the adjacent …

Crustal thickness along the western Galápagos Spreading Center and the compensation of the Galápagos hotspot swell
Wide-angle refraction and multichannel reflection seismic data show that oceanic crust
along the Galápagos Spreading Center (GSC) between 97° W and 91° 25′ W thickens by …

Joint flexural-density modeling of the Taltal, Copiapó, and Iquique hotspot ridges and the surrounding oceanic plate, offshore Chile
Based on gravity and bathymetric data and using a novel two-dimensional joint flexural-
density modeling approach, this work studies the physical properties of the oceanic Nazca …
