Is it a pseudomorph, coating or something else? Galenitt & Chalcopyrite
July 04, 2012 04:58PM
Hi! I have a specimen of rose quarz covered with calcite+ chalcopyrite, pirite and galenite from Madagascar. After a close look I noticed a strange cubic chalcopyrite crystall. As far as I know, that form is not typical for that mineral, so I took some photos (1, 3) with my microscope and found out that there are galenite & chalcopyrite. Unfortunately the cube is very hard to reach and i was not able to take better photos. Photo number three is a piece from the same specimen which seems similar. So, what is it?
Thank you.

I doubt about the white balance on your photo, but even in this case these crystals looks like pyrite to me... not a galena or chalcopyrite...
Maybe better photos might help.. Also do you have more detailed information on locality?
Ok, I will try to take better photos, but I am shure that it is not a usual pirite cube. There is a couple of pirits on that specimen, and they have less intensive gold colour and "stripes".
Here is a couple of better photos.
