A remarkable specimen from Sterling Hill’s North Orebody that displays obvious segregations of, and transitions between, both major forms of sussexite: pinkish-lavender cherty sussexite, and laths of tan fibrous sussexite which in this example appear to be pseudomorphs after blocky crystals of an earlier mineral. Note that the sussexite fibers are mostly parallel to the precursor mineral, but at right angles to it in places along the crystal margins. The orange traces are zincite, and the black areas are probably pyrochroite. This is another showpiece from the collection of Steven Phillips.
