Webcleavage, tendency of a crystalline substance to split into fragments bounded by plane surfaces. Although cleavage surfaces are seldom as flat as crystal faces, the angles between them are highly characteristic and valuable in identifying a crystalline material. WebCleavage Tendency of a crystalline mineral to break in certain directions yielding more or less smooth planar surfaces.These planes of lowest bond energy have minimum value of cohesion. An amorphous body of course has no cleavage. Cleavage planes are usually // to the crystallographic planes. Exceptions: Cal, Flu. 1. Good, distinct, perfect, 2.
