This subduction-uplift system was accompanied with the intrusion of considerable quantities of magma through the mantle, 1st in the form of the volcanic arc together the western fringe of the South American Plate and later by the injection of sizzling answers into bordering continental rocks; the latter procedure created many dikes and veins that contains concentrations of economically important minerals that afterwards have been to play a significant role within the human profession of your Andes.
