Photo 12.4 Dark colored salt flowing from Zagros Mountains in southern Iran, a zone of collision and uplift. The salt is less dense than the surrounding rock and moves upward as diapiars. When these diapiars reach the surface, the salt flows ductily under gravity-induced stress. http://www.solarviews.com/cap/earth/saltglacier.htm
