Slab to back-arc to arc: Fluid and melt pathways through the mantle wedge beneath the Lesser Antilles.

The article highlights a study on seismic attenuation beneath the Lesser Antilles arc, an end-member system that slowly subducts old, tectonized lithosphere to understand the view of fundamental mantle wedge processes. It focuses on the end-member Lesser Antilles arc (LAA) system due to its slow consumption of old (80 to 120 million years), slow-spread lithosphere and also shows the l variations in the hydration state of the oceanic lithosphere before its subduction into the Antilles trench.
