This subduction-uplift approach was accompanied because of the intrusion of considerable portions of magma from the mantle, initial in the form of the volcanic arc together the western fringe of the South American Plate and later on because of the injection of incredibly hot alternatives into bordering continental rocks; the latter course of action made various dikes and veins made up of concentrations of economically precious minerals that later on have been to Perform a crucial function in the human profession with the Andes.
