JUNITOITE

Junitoite, a calcium zinc silicate hydrate mineral, is rare at Franklin and has not been found at Sterling Hill. It was found on one specimen, as 0.3 mm white to colorless, bladed crystals, in subparallel and slightly divergent arrays. The luster is vitreous on fresh surfaces, dull on crystal faces, and pearly on the good cleavage. It was identified by its unique X-ray powder pattern; the crystals have not been chemically analysed. Franklin junitoite occurs in a vein in franklinite on a garnet druse, associated with sparse clinohedrite, blue-fluorescent calcite, aragonite in radial sheave-like aggregates, and white bulbous hemimorphite. Some junitoite may respose in mineral collections misidentified as hemimorphite. (Dunn, 1995)
