Mode of occurrence and cause of twinning, which are occasionally observed in lithium tetraborate crystals grown pararell to , have been investigated. Twinning is related to the crystal symmetry, i.e., 4-fold screw axis along the c-axis. Relashionship between the cause of striations in crystals and the occurence of twinning during growth has also been examined in connection with temperature fluctuations near the interface.
