Comment: Bisbee fans (and they are legion!) love the rare examples of this phenomenon that come onto the market from time to time: mine timbers from the very old works that, over time, stalactitic, botryoidal aragonite formed on - which in turn got a pretty green color from copper staining. The mine timbers themselves have turned into a highly collectible mineral specimen! Once this was considered a cuprian aragonite variety called locally "brucksite." in the recently acquired Mullane Collection (They were dealers til the early 70s, and then the collection was lost until recently when I was able to find and buy it).
Minerals: Aragonite (CaCO3)
