Cleavage \Cleav"age\, n.
1. The act of cleaving or splitting.
[1913 Webster]
2. (Crystallog.) The quality possessed by many crystallized
substances of splitting readily in one or more definite
directions, in which the cohesive attraction is a minimum,
affording more or less smooth surfaces; the direction of
the dividing plane; a fragment obtained by cleaving, as of
a diamond. See Parting.
[1913 Webster]
3. (Geol.) Division into lamin[ae], like slate, with the
lamination not necessarily parallel to the plane of
deposition; -- usually produced by pressure.

or to the plane of the lateral axes.
Cell cleavage (Biol.), multiplication of cells by fission.
See Segmentation.
Cubic cleavage, cleavage parallel to the faces of a cube.
Diagonal cleavage, cleavage parallel to ta diagonal plane.
Egg clavage. (Biol.) See Segmentation.
