This is the “back” side of the same specimen shown in photo SSX15a, but here the transition from altered ore (base of specimen) to massive brown sussexite and then to tan fibrous sussexite is more readily apparent. Note also the thin layers of pinkish cherty sussexite between the thicker brown sussexite and ore, and the similarity of this sequence to that of specimen SSX44.
