Spring 2015
Gravitational removal of the dense lower lithosphere is proposed to be a fundamental process in continental tectonics. This has been used to explain seismological observations of an abnormally thin lithosphere beneath some regions and evidence for detached lithospheric materials at 100-200 km...

The central Andes (18° - 26°S) is an active Cordilleran orogen, formed through the subduction of the Nazca oceanic plate beneath the South American continent. Despite significant tectonic crustal shortening and thickening (60 -70 km), deep seismic imaging indicates a thin to absent mantle...
