The Andean subduction zone is an excellent place to study deformation within a subducting
slab as a function of depth, owing to the varying and well-resolved geometry of the subducting Nazca slab
beneath South America. Here we combine the results of source-side shear wave splitting with the latest
regional tomography model to isolate intraslab raypaths and determine the spatial distribution of
anisotropy within the Nazca slab. We observe that in the upper mantle, the intraslab anisotropy...[Show more]
