WebCleavage is a type of secondary foliation associated with fine grained rocks. For coarser grained rocks, schistosity is used to describe secondary foliation. There are a variety of definitions for cleavage, which may cause confusion and debate. The terminology used in this article is based largely on Passchier and Trouw (2005). WebShale is characterized by breaks along thin laminae or parallel layering or bedding less than one centimeter in thickness, called fissility. It is the most common sedimentary rock. Argillite: It has undergone low-grade metamorphism. Argillaceous rocks are basically lithified muds and oozes. They contain variable amounts of silt-sized particles.

WebMetamorphic Rocks. Metamorphic rocks are any rock type that has been altered by heat, pressure, and/or the chemical action of fluids and gases. Metamorphic rocks are classified by their structure and their dominant minerals.
