Internal deformation of the subducted Nazca slab inferred from seismic anisotropy

open access: yes, 2016
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 align with the direction of plate spreading1, 2.

The lack of correlation between flat slabs and bathymetric impactors in South America [PDF]

open access: yes, 2013
Flat slab subduction has been attributed to various causes including mantle wedge dynamics, overriding by the upper plate, age of the subducting plate, and subduction of anomalously thick oceanic crust. One often favored explanation for flat slabs is the
