Kawazulite
Rendaiji, Shimoda city, Shizuoka pref., Japan
This locality is closed to collecting.
Field of view: 5 mm. Kawazulite associated with tellurium. The micaceous silver-white crystal with a metallic luster is kawazulite. The dark gray grains around kawazulite are tellurium. The opaque white host is fine massive gangue quartz, and the yellow parts of quartz are due to tellurium contamination.
Recovered from a quartz vein in a moderate-temperature hydrothermal deposit associated with andesitic-basaltic pyroclastic rocks of an oceanic arc subjected to propylitization alteration. Formed in the early Pleistocene (1.5 Ma).
The first kawazulite in the world was described from this location in 1970.
