Identity HelpIs this harmotome or analcime?

Hi David,
It looks like Analcime to me but you will be the best judge since you have it there. The locality is well known for great examples of Analcime. There are some differences between the two that can help you distinguish one from another. The characteristic shapes of both is a good place to start. Take a look at the crystal atlas rotating animation (especially #2) on the Analcime page here. http://www.mindat.org/min-210.html Does it have any evidence of good cleavage? Harmotome will often show a good cleavage, Analcime won't. Also Analcime is a bit harder. Good luck with it.
