Warikahnite

Warikahnite is a rare zinc arsenate mineral of the triclinic crystal system with Hermann- Mauguin notation , belonging to the space group P. It occurs in the Tsumeb mine in Namibia on corroded tennantite in the second oxidation zone under hydrothermal conditions in a dolostone-hosted polymetallic ore deposit.〔〔Anthony, J. W., Bideaux, R. A., Bladh, K. W., and Nichols, M. C. (2000) Handbook of Mineralogy. Volume IV: Arsenates, Phosphates and Vanadates. Mineral Data Publishing Company, Tucson, Arizons, p. 644〕 It is associated with adamite, stranskiite, koritnigite, claudetite, tsumcorite, and ludlockite. The origin of discovery was in a dolostone ore formation within an oxidized hydrothermal zone, in the E9 pillar, 31st level of the Tsumeb Mine in Namibia, Southwest Africa.〔〔 It has also been found at Lavrion, Greece and Plaka, Greece as microscopic white needles.〔
==Discovery==

Warikahnite was discovered by Clive Queit〔 at Tsumeb mine and was first described in 1979 by Keller, Hess, and Dunn.〔〔 The name "warikahnite" honors Walter Richard Kahn, who was born in 1911. He was from Bayersoien, Germany, and he was a dealer and collector that specialized in Tsumeb minerals. He was honored due to his support of research into rare secondary minerals.〔 The type material is located at the University of Stuttgart, the Smithsonian Institution, and Harvard University.〔〔
