Luxullianite

Index Luxullianite

Luxullianite (also Luxulyanite, Luxulianite) is a rare type of granite, notable for the presence of clusters of radially arranged acicular tourmaline crystals enclosed by phenocrysts of orthoclase and quartz in a matrix of quartz, tourmaline, alkali feldspar, brown mica, and cassiterite. [1]
