Graphite cleavege or fracture
WebBiotite is very easy to identify, and with a little experience a person will be able to recognize it on sight. It is a black mica with perfect cleavage and a vitreous luster on the cleavage faces. When biotite is separated into thin sheets, the sheets are flexible but will break upon severe bending.

WebIn this material with an h.c.p. crystallographic structure, cleavage fracture can be modeled as a combination of a critical normal stress, σ n, and a critical resolved shear stress, τ, applied to the basal slip plane, which is also the predominant slip plane. 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.
