|Journal title:||Memoirs of the Faculty of Science, Kyoto University. Series of geology and mineralogy|
|Abstract:||The contiguous polysynthetic twin lamellae in labradorite from Labrador and in andesine from Sannidal are not always the same sort of plagioclase. In some cases, one side lamella is built up from a high albite lattice, while the other side lamella from an intermediate plagioclase lattice, whose X-ray photograph is characterized by pairs of weak (e)-reflexions.|
