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.
Gneiss, a foliated metamorphic rock. Marble, non-foliated metamorphic rock. Examples of foliated and non-foliated metamorphic rocks are shown above. On the left is gneiss, showing minerals aligned along visible planes typical of foliated metamorphic rocks. Gneiss can form from the metamorphism of granite.On the above right is a picture of marble, a typical non-foliated metamorphic rock.xamples of foliated and non-foliated metamorphic rocks are shown above.
