Three-Dimensional Velocity Structure and Crustal Thickness Beneath a Slow-Spreading Ridge

Abstract

This study will provide improved resolution of 3D structure and the first 3D images of lower crustal/upper mantle structure beneath a slow-spreading ridge. The results will constrain models of magma plumbing. The project requires some technique development to best combine the wide-angle reflection and refraction data, and will provide insights into the 3D nature of the ridge thermal structure, the existence of any deep crustal or mantle magma reservoirs, the variability in magma supply along the ridge, and the importance of along-axis transport of magma at deep versus shallow levels.
