The main xl is 2.4 mm long. Thanks to Ralph Thomas. MOB coll. Clearly there is titanite. I think the other minerals are actinolite (dark green amphibole, acicular to fibrous in part), “chlorite”, albite and “apatite” (penetrating the titanite). See http://www.mindat.org/photo-46359.html for a very similar assemblage. Due to ...

A piece of massive chalcocite found as a thin seam in a sandstone outcrop near the top of the dump. Chalcocite was the principal ore mineral at the mine, which was the first copper mine (1750) in what is now the US. At the bottom of one the shafts are the remains of the first steam engine in America.

It's important to remember that pseudomalachite is a copper phosphate species, not a copper carbonate like malachite, but they are so similar in appearance, that the name pseudomalachite is more than appropriate.
