Grenville, Miner's Bay, Ontario
The Miner's Bay Locality is a place where superb Tremolite crystals have been collected. Not much has been forthcoming in recent years but I was fortunate to tap into a cache of crystals collected years ago. I originally had these crystals labelled as actinolite, thinking they were on the iron-rich end of the actinolite-tremolite series. I have since learned that although they can be 50/50 actinolite/tremolite, they are most often tremolite.
