Fassaite

Fassaite

Fassaite is a variety of augite but having a very low iron content. It is named after the Fassa Valley, Italy. Some authorities do not recognize it as a separate mineral but continue to class it with Augite.

It is thought to be a contact mineral formed at high pressure on the interface between volcanic rocks and limestone.
