Granito delle Alpi, from the Alps; or perhaps from Predazzo, Trentino or elsewhere in Trentino-Alto Adige, Italy
Geological description:
Coarse-grained quartz diorite with pale green plagioclase. Brown is filler/polishing compound.
Comments:
Resembles a diorite from Predazzo, Trento, Italy in the Naturhistorisches Museum Wien, and may well be from the Trentini-Alto Adige area. Brown areas are largely filler/polishing compound.
