Foliation is the result of the parallel arrangement of (micas, etc.) in a plane perpendicular to the maximum principal applied stress. A lineation is caused by a similar growth of elongate minerals (eg. hornblende) in this plane. Slate, schist, and gneiss are three common foliated metamorphic rocks.
Major Concepts. 1  Foliated rocks - slate, phyllite, schist, gneiss, mylonite. 2  Non-foliated rocks - quartzite, marble, hornfels, greenstone, granulite. 3  Mineral zones are used to recognize metamorphic facies produced by systematic pressure and temperature changes.
