ZINC CARBONATE AND RELATED COPPER CARBONATE ORES AT
zinc carbonate ore was not shipped from it until 1913. On July 23, 1914, the writer visited the two mines, the Cliff and Hidden Treas- ^ ure, that were shipping zinc carbonate ore. The output of this ore ^ from each mine was small, but the deposits presented some very interesting features, the principal of which were the marked lamellar structure of the zinc carbonate in contrast to that in
