Subject category Comment text
Deposit "Arsenopyrite is an accessory mineral found in a copper deposit located at the contact of the Paleozoic and pre-Cambrain rocks (Bull. 50, p. 7)"
Deposit "A coarse, conglomaratic sandstone at the base of the Guernsey Formation overlies a rough, uneven surface of pre-Cambrian limestone which shows enlarged joint planes, sink holes, and other solution features. Malachite, chrysocolla, azurite, and chalcocite replaced the cement of the sandstone, and locally attacked limestone pebbles. Sometimes these minerals, as well as olivenite, fill fractures. Tufted crystal aggregates of malachite, and botryoidal masses of chrysocolla were found in solution cavitites. White or yellowish calcite incrusts these minerals, and films of bluish-white chalcedony commonly cover the calcite. Thin stringers of malachite, chrysocolla, and azurite extend downward into the pre-Cambrain limestone (Bull. 50, p. 54)."
