lpro 2020 0 Posted March 5 Share Posted March 5 I put this in a presentation two years ago and didn't label it. Now I can't remember what it is! Can anyone identify this mineral for me? Quote Link to post Share on other sites

tfrandy 1 Posted March 6 Share Posted March 6 I'm almost inclined to think it could be actinolite. 1 Quote Link to post Share on other sites
fuss 40 Posted March 6 Share Posted March 6 (edited) I'd guess one of the Amphibole asbestos minerals based on the photo. Edited March 6 by fuss Quote Link to post Share on other sites
lpro 2020 0 Posted March 6 Author Share Posted March 6 I may have figured it out. I think this was a quick grab meant to show chlorite, although I'd never identify it as that from its appearance. I was also wondering about asbestos, and I like the kyanite answer! Thank you all! Quote Link to post Share on other sites
Old Tom 1,083 Posted March 6 Share Posted March 6 If the long strands are fibrous I would almost go with asbestos. From the pic they almost look crystalline. Asbestos forms in a crack from one side to the other unlike the picture. Old Tom Quote Link to post Share on other sites
