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

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