Eastern Sierras Pampeanas, Lithospheric Structure above the variably dipping Nazca Slab

In Central Argentina, the Nazca plate subducts at a very low angle and remains at shallow depths for 100s of kilometers before sinking into the mantle; this is the most extreme example of present day shallow subduction in the world. This project is focused on identifying the mechanisms through which forces could be transferred from descending Nazca plate up through the mantle wedge and into the S.American lithosphere
