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.
Metamorphic rock fabrics and textures. Foliated rocks have a âfabricâ, called a foliation, caused by the parallel alignment of mineral grains.
