Naka, Shimoda city, Shizuoka pref., Japan
Source for "azurite blue", silicon copper
Field of view: 3 mm. Groups of azurite. The blue parts are aggregates of fine tabular azurite. The basement is gangue quartz encrusted with thin brown limonite.
Recovered from a quartz vein in a meteoric oxidation zone of a moderate-temperature hydrothermal deposit associated with andesitic-basaltic pyroclastic rocks of a oceanic arc subjected to propylitization alteration.
Azurite from this location was described in 1982.
