Hi Rock, I have Orthoclase after Scapolite from Kragero, Norway, and it is exactly the same as the one from Canada.

Spencer.

Hi Rock,

The Herja Mine in Romania produced some nice pseudomorphs of pyrite after pyrrhotite. Here is an example if you want to include it in this section of pseudomorphs. It has been uploaded to the Mindat gallery.

Michael,

Added!

Iv'e seen better, but not in Mindat's database and your specimen is good enough. Thanks

Rock,

I uploaded this today:


It might by relevant for this article. I've included some information on the occurance in the photo caption.

Pinite= Muscovite after cordierite

Milo

You forgot to include these:[www.mindat.org]

Reiner,
You are right, those snuck past me. Thanks for bringing them to my attention. I put all three in the article. Neat specimens. I never saw one for sale. Did you collect them? How many were found?

See photo 531138 that I uploaded today of a group of Feldspar crystals pseudomorph after Marialite. John S.

John,
Those are interesting and now in the article. Can you tell us something about the occurrence?
