Figure 10.9. Various forms of rock-crystal twinned according to the Japan law from Narushima Island. Nagasaki Prefecture. Japan. The evolution of crystal forms in the order a->b->c is expected as growth proceeds, due to the re-entrant corner or pseudo re-entrant corner effect. Figure 10.9.

Figure 1.2 Japan law contact twin quartz crystal. This type of twinning was discovered in 1829 by C. S. Weiss in quartz crystal from the La Gardette mine in France. However, because of the abundance of these specimens in Japan, they are now known as Japanese twins. Figure 1.2 Japan law contact twin quartz crystal.
