GeneralNeed 'Pyrite Disease' Photos
17th Oct 2019 21:04 UTCSteve Hardinger 🌟 Expert
Looking for pictures of mineral(s) suffering from advanced 'pyrite disease'. Pyrite, marcasite, pyrrhotite, etc. Examples with accompanying decomposed labels are especially desirable.

please don't start multiple identical threads, even in different forums.
I closed the one in the "mineral photography" forum... the one here in "general" should get plenty of views from the membership.

Here's a relatively recent and authoritative-looking article on pyrite disease:

I think this may be an example of what you were looking for only this piece is principally arsenopyrite from Ramsley Mine in Devon. This piece has been slowly growing these filaments for 10 years. I have however acquired pieces just recently that even after a month are beginning to 'grow'.
I have had a piece of marcasite that degraded and burnt its way through the cardboard and took a good deal of the paint off the metal tray below before I found it.
