...talking about fluorescence...

Post by crocoite »

This is a calcite cleavage (calcite breaks naturally into rhombohedral pieces). The first shot is in normal light, the second under longwave ultraviolet light. Lovely pink colour.

Interesting photos Steve :D , both that of the Aragonite and this one of the Calcite. I have yet to try and subject lichens to ultraviolet, I have read that they too display different colors by having absorbed minerals from the substrate to which they cling and from some airborne particles aswell, I think. :-k

WOW, now thats what I was talking about Steve. There is a rock & mineral flea market that happens close to my town every year and they usually have a dark tent with bolders of glowing minerals. Very cool to see. Very nice shots. :smt023
