WebNov 18, 2024 · Cleavage is a tectonic foliation, meaning it is a sub-planar, often parallel, preferred fabric that develops in low-grade rocks. A fabric is any geometrical arrangement of features in the rock. As a tectonic foliation, cleavage occurs as a response to tectonic activity. However, it forms without the loss of cohesion and is not a fracture.
