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.
Kinds of Metamorphic Rocks â¢Gneiss-a coarse grained granular rock in which foliation results from alternating layers of light and dark minerals. Compositionally similar to granite with quartz, feldspar, biotite, and amphibole. Forms during regional high grade metamorphism.inds of Metamorphic Rocks â¢ Slate-low grade metamorphosed shale; very fine grained; slaty cleavage should not be confused with bedding planes.â¢ Phyllite-next step up from slate, larger mica grains give the rock a luster.â¢Schist-a strongly foliated rock with large grains of platy minerals.
