Abstract
Mineral cleavage can be resolved into two components; cleavability and optical effect. The electrical theory of matter in the solid state leads to a quantitative expression for the cleavability of ionic minerals
C{hkl} = A(hkl)/Σínisicos θ i
Approximate values for s are obtainable by using the electrostatic bond strength. Systematic application to minerals whose constituent atoms have inert-gas cores gives good agreement with observation.
