Most interesting were several small specimens covered with tiny dark green libethenite crystals; I bought these for less than a song, and two days later the geologist showed up at the hotel with about 200 more libethenite specimens.
Associated minerals include malachite, libethenite and an unidentified iron oxide species.

The chemistry of formation of chrysocolla, -Cu[H.sub.2]Si[O.sub.4][center dot][H.sub.2]O, pseudomalachite, libethenite, [Cu.sub.2]P[O.sub.4]OH, and cornetite, [Cu.sub.3]P[O.sub.4][(OH).sub.3], has been described (Williams, 1990, 1996) and can be related to general weathering processes and reported mineral assemblages.
