RM2950   Crossite, riebeckite-glaucophane

Hallberg, Rigaus, Abtenau, Hallein, Salzburg, Austria

In this sample we can observe a large group of prismatic crystals, acicular, bright, with a dark violet to lavender color. The original description of this piece referred to a mineral from the amphibole supergroup called "crossite". This species is currently discredited and it is an intermediate between riebeckite and glaucophane groups. The specimens from this Austrian locality are very characteristic.


Size: 5 x 3.5 x 2.3 cm.
