Talk:Vaterite

Colour
The vaterite crystals can be greater than 10 microns in diameter. I am doing research on Molar Tooth fabrics, and most of the former vaterite crystals are greater than 10 microns.One of my SEM images

How can vaterite be called 'colourless' if it only exists in particles with sizes on the order of visible light wavelengths? —Preceding unsigned comment added by 131.111.214.77 (talk) 10:32, 12 November 2008 (UTC)

Questionable photo
I highly doubt that the photo shows vaterite. Similar crystals from other occurrences are always calcite, and I am not aware of such large vaterite crystals (compare http://www.mindat.org/gallery.php?min=4161).

Stabilizer (and destabilizer)
I think I have read that RE ions stabilize vaterite. The source of this information was probably the German mineral magazine Lapis in the second part of the 80s but this is probably not a primary source. According o the monohydrocalcite article Mg inhibits the formation of vaterite (and even calcite)
