Thanks for taking all the time in making these videos, an amateur collector here, who like a lot of amateurs were taken into the geological world when their kids picked up random rocks, your well explained and thought out videos are truly appreciated!
I guessed aragonite too at first although that was just a gut reaction 😂 Also, I was wondering if you could give a few words on chiastolites/andalusites if you know about them? I live near the Wachusett reservoir, and have found many samples embedded in shale and schist, as well as some staurolite mica schist specimens, although I know very little about them. Cheers!
I'm no metamorphic petrologist, but those chiastolites have a pretty distinctive cross if you see an end section of the crystal. Staurolites sometimes make distinctive twinned crystals. Otherwise they look quite similar to amphiboles.
SW and LW UV light may help, I use it on all non metallic minerals as its cost effective and a good way to identify some minerals or trace element impurities in minerals such as fluorite.

Thanks. The curiosity of kids is a valuable thing!
Good show. I enjoyed this more than expected. Aragonite is slightly more dense and slightly harder than calcite too.
I wish we had exercises like that when I was studying. It was fun :)
Great fun to watch. Especially appreciated how you estimated volume of the specimen. Hadn't seen that before.
It's an old text book method, but only works on large pure crystals.
my bet was aragonite from the start. very nice investigative work!
It was certainly a contender.
Unlikely because of the size of the crystals. That would probably be the largest synchysite-(Ce) crystals ever found.
That was a distinct possibility from Zaaiplaats. The mine produced some huge crystal specimens of fluorite, smoky quartz and cassiterite.
As always a great video. Hadn't seen you in while. Good to see you back.
Thanks. My real job gets in the way of my camera sometimes ;)
Nice and analytical. Thank you 🙏. So easy to understand for me the geology lover but unqualified.😅
The old text books still do the job when you don't have a $40,000 PXRF machine on hand.
Love those crystals
So do I!
wow thanks for that idea !
i couldn’t find that other kind of scale around so that idea will work for me too
Necessity is the mother of invention :)

Awesome. Thanks for furthering my edjamication.. :)

👌👌👌
Pretty good video :) u should do a couple more like this
It's on my to do list, but there are a lot of things on that list!
SW and LW UV light may help, I use it on all non metallic minerals as its cost effective and a good way to identify some minerals or trace element impurities in minerals such as fluorite.
I probably should get one!
Haha calcite all along damn it!
Doh!
