The Mineral Identification Key Copper, Michigan, Seaman Museum specimen

 Minerals with cleavage

Microcline feldspar,
 South Dakota, 4cm long.
 Perfect cleavage is the right face.
 Good cleavage is the top face


Perfect cleavage - cleavage is planar (the lines on the surface
 are another feldspar which has weathered somewhat).


Good cleavage is easily seen, but it is not totally planar 
(there are some bumps in cleavage surface)
