Sphalerite
Rendaiji, Shimoda city, Shizuoka pref., Japan
This locality is closed to collecting.
Source for Zinc, Cadmium, and Sulfuric acid.
Field of view: 40 mm. A network of sphalerite. The network-like groups of dark green grains exhibiting perfect cleavage are sphalerite. The surrounding translucent white host is gangue quartz. The brown crusts are limonite formed by weathering.
Recovered from a quartz vein in a moderate-temperature hydrothermal deposit associated with andesitic to basaltic pyroclastic rocks of an oceanic arc subjected to propylitization alteration. Formed in the early Pleistocene (1.5 Ma).
Sphalerite from this location was described in 1924.
