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.
WebFair cleavage means that some samples may show all of their cleavage surfaces while others may not show their cleavage well. Poor cleavage means that smooth surfaces are rarly seen and that you must use the overall shape of the broken sample to determine the cleavage (or examine the broken surfaces with a magnifying glass to see the cleavage). glock first personWebMinerals will poor cleavage will resist splitting.
