Distribution

Very rare. Mainly (exclusively ?) second oxidation zone.

Occurrence

  • Supergene
  • 2nd Oxidation Zone

Notable Finds

Found on 30 Level in 1964, with tsumcorite, which is a rare association.

Paragenetic and General Notes

Acicular translucent crystals and radial crystal aggregates with crystals to 10 mm were found in the second oxidation zone and are regarded as best of species (Von Bezing, 2007).
