High‐Resolution 3‐D Lithospheric Structure of the Subducting Carnegie Ridge and the Ecuadorian Margin Imaged From Teleseismic Receiver Functions

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The Ecuadorian margin is a forearc‐arc system shaped by oceanic terrane accretion and Carnegie Ridge subduction, yet the accretion mechanism and ridge subduction extent remain poorly constrained. Using teleseismic P‐wave receiver functions from dense seismic arrays, we image velocity discontinuities within the overriding plate and subducting ...
