WebCleavage is a property related to characteristics of the mineral’s crystal structure. The cleavage planes are parallel to the lattice planes most densely packed with atoms, that is, planes with the greatest reticular density; the binding force between these planes is minimal. http://webmineral.com/help/Cleavage.shtml
