Schist is a metamorphic rock that displays a foliated (folded) texture as a result of intense pressure that causes alignment of platy minerals. Metamorphism,intense heat and pressure,causes the rearranging or recrystallization of components in a rock,to create a new rock with new minerals. Impure limestones can be transformed by metamorphism in this way; actinolite schist,a rock made up almost entirely of the mineral actinolite,is one possible result | |
