Notes:
Termination of planar defects has been observed in the amphibole mineral nephrite [Ca2(Mg,Fe)5(Si4O11)2- (OH)2]. Isolated terminations, which disrupt the crystal structure, are rare, but the cooperative termination of two defects, in which the total number of silicate chains is conserved and structural disruption is minimized, is more common. Two different kinds of cooperative termination have been observed. Occasionally, defects are seen to terminate and shift their line of propagation through a crystal.
