Improving Mindat.orgChromium-dravite error?

18th Aug 2013 22:04 UTCIlkka Mikkola Expert

The Kokka, Kaavi, Finland tourmaline was identified as Chromium-tourmaline without Cr-analysis: Huhma Aarto 1964 Outokummun aineistot 001/4311/AH/64. It is only chromium-bearing dravite if there is not any Cr-analysis.

The reference given for the entry of "Chromium-dravite" on the Kokka locality page is http://tw.strahlen.org/fotoatlas1/chromdravite_foto.html


Perhaps Dr. Thomas Witzke did some analysis on his specimen ?


Tourmaline added with your reference on locality page. What is the full title of Huhma & Aarto's report? Could you please add it?
