Cleavge of rocks

Cleavage is a type of rock foliation, a fabric element that describes the way planar features develop in a rock. Foliation is separated into two groups: primary and secondary. Primary deals with igneous and sedimentary rocks, while secondary deals with rocks that undergo metamorphism as a result of … See more Cleavage, in structural geology and petrology, describes a type of planar rock feature that develops as a result of deformation and metamorphism.
