Hintergrund   The movements of the Continental Crust and Lithosphere constrain the Oceanic Crust, Lithosphere and Asthenosphere to move downwards. This causes the Continental Crust to fold and lift up, producing volcanic activity.   Profile between Muelle Llico (Chile), 34°45’16”S 72°05’03”W and Malargue (Argentina), 35°30’S 69°35’W.
