Very rare. First recognised from the second oxidation zone, in the 1970s (Gebhard, 1999).
- 2nd Oxidation Zone
Radiating, colourless-to-white sprays of elongated crystals from the second oxidation zone are considered to be best of species. According to Von Bezing et al. (2014), some 60-80 specimens were recovered from this find. The crystals were at first mistaken for aragonite.
