Upper mantle anisotropy beneath Peru from SKS splitting: Constraints on flat slab dynamics and interaction with the Nazca Ridge

CM Eakin, MD Long, LS Wagner, SL Beck… - Earth and Planetary …, 2015 - Elsevier
The Peruvian flat slab is by far the largest region of flat subduction in the world today, but
aspects of its structure and dynamics remain poorly understood. In particular, questions …

Internal deformation of the subducted Nazca slab inferred from seismic anisotropy

CM Eakin, MD Long, A Scire, SL Beck, LS Wagner… - Nature …, 2016 - nature.com
Within oceanic lithosphere a fossilized fabric is often preserved originating from the time of
plate formation. Such fabric is thought to form at the mid-ocean ridge when olivine crystals …

Response of the mantle to flat slab evolution: Insights from local S splitting beneath Peru
