Hydrozincite |
| ZnCO3.Zn(OH)2 |
Hydrozincite forms flaky incrustations of pale yellowish-white color and pearly luster. It has been found only as an alteration product of sphalerite in a cross vein near the shaft house of the Trotter mine at Franklin. The vein—sphalerite and pyrite in a calcite gangue—is reduced to a cavernous mass of calcite, the openings in which are partly filled with ocherous smithsonite. In some of the cavities, however, hydrozincite takes the place of the normal carbonate. Although it might be expected, this mineral was not detected on any of the many specimens of calamine from Sterling Hill that were examined.
