Azurite

Field of view: 5 mm. A group of azurite and malachite perched on the crystallized limestone. The blue part is a group of tabular azurite crystals. The green part at the right is malachite. The massive white basement is aggregate of granular calcite.

Recovered from a meteoric oxidation zone of a pneumatolytic deposit combined with skarn formed by contact metamorphism of S-type (ilmenite-series) granite.

Azurite from this location was described in 1909.
