Cleavage of albite
WebAlbite twins are always parallel to (010). However, in anorthoclase (Fig. 13) Pericline twins are nearly parallel to (001), whereas in microcline (Fig. 15) Pericline twins are approximately normal to (001). In anorthoclase two cleavages are visible when both sets of twins are clearly defined, whereas in microcline only one cleavage is visible. WebTwinning is almost universal in albite. Crystals can be twinned according to the Albite, Carlsbad, Manebach and Baveno laws. Albite is a common constituent of granitic and syenite rocks. Can also be massive. …
