Biotite cleveage
WebGeometric Models. Cleavage means the separation by breakage of a mineral into fragments across planes of weakness in chemical bonds. Because the orientation of ions and molecules in a mineral is geometrical and repetitive, minerals fragment into the same geometric shape - for example, bigger cubes and smaller cubes. http://www.minsocam.org/msa/collectors_corner/id/mineral_id_keyi6.htm
