[Rockhounds] Lipidolite and the micas

[Axel Emmermann]

Hi Ed,

The niobium-columbium confusion is quite similar to  tungsten-wolfram.
The mineral wolframite is a tungstate of manganese. It was named in Europe
and would otherwise have been named tungstite.

BTW: did you get my last messages? I keep getting
<edwardjwagner at bellsouth.net>: delivery temporarily suspended: connect to
gateway-f1.isp.att.net[204.127.217.16]: Connection timed out

Or an error they call 550 (something about being blocked and abuse... Which
I can hardly believe. Were we ever abusive???)

Cheers
Axel
