> Yes, you are right, Axel...............

Well, ir's a possible explanation. Another possibility that crossed my mind
is that the aragonite may have grown on thin needles of a more soluble
mineral like gypsum or maybe even on capilairy-roots of plants that my nave
hung from a cavern ceiling. Just ideas, I really don't have the foggiest
notion ;-)))

Yes, that's it.

That's mighty friendly, Larry. However, I collect only specimens that
fluoresce in UV and only if they come with a location. I have a similar
specimen from Greece. It doesn't fluoresce, alas ;-)))
Maybe donate it in my behalf next time someone needs specimens to hand out
to kids or some other school project?
Actually , I haven't seen much fluorescing Flos-ferri yet... Rather
surprising since aragonte is often fluorescent.

Cheers
Axel
