Additional information / Summary

Plagioklas ist ein Synonym für die Anorthit-Albit-Serie. Darunter gibt es Mischkristalle aus dem Calcium-Feldspat Anorthit und dem Natrium-Feldspat Albit.

Je nach Zusammensetzung bekommen die Mischkristalle eigene Namen.

Andesin, Bytownit, Labradorit und Oligoklas sind keine eigenständigen, IMA-anerkannten Mineralien.
