| Species: | Alumoklyuchevskite |
| Formula: | K3Cu3(Al,Fe3+)(SO4)4O2 |
| Comments: | From thesecond cone of the Northern Breakthrough.
Alumoklyuchevskite occurs as aggregates of dark green acicular crystals, elongate <010>, to 1 mm length and <0.1 mm width. Almost equant in cross-section, transparent,…Turns white on exposure to air, probably by hydration. |
