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.
exists and is an alternate of . The difference lies in the degree of metamorphism. Metamorphism is the solid state recrystallisation of minerals. Both rocks are metamorphosed by regional metamorphism (directed pressure), however schist is metamorphosed more than slate. Therefore Slate is only a low grade metamorphic rock whereas schist is a medium grade metamorphic rock (gneiss is high grade).
