Question : de quoi sont constitués les cristaux blancs qui forment la base ? De fluorite également ? De quartz ? D'autre chose ? Johann Grimm - Et le lézard traversa la rivière... (talk) 10:20, 1 November 2010 (UTC)
what are the white things in the background? edit
To use this image illustratively need to know that. Should have been raised when voting on FP.TCO (talk) 03:45, 7 June 2011 (UTC)
- According to the English article the color of the mineral can be "Colorless, white, purple, blue, green, yellow, orange, red, pink, brown, bluish black;", "Color zoning or banding is commonly present. The color of the fluorite is determined by factors including impurities, exposure to radiation, and the size of the color centers.". Take a look at Category:Fluorite as well. The mineral is composed of Calcium and Fluorine, I guess the former gives it the "white things". Neukoln (talk) 00:46, 8 June 2011 (UTC)
