Re: Rocks and Minerals Question Marathon
I would say augite. It's an inosilicate.. the info iv'e gathered says it can have either single or double chains, but single is more common. not sure if thats the answer your'e looking for or not

Re: Rocks and Minerals Question Marathon
Correct, I always thought it only had single chains though... Also do you have any tips on how to tell it apart from hornblende?
