Hydrated normal arsenate, zinc mineral
Specific gravity: 4.24
Colour: Colourless to light yellow
Solubility: Dissolves in hot hydrochloric and nitric acid (Dana)
Warikhanite is a rare secondary arsenate formed by alteration of
tennantite in an oxidised zone in a
dolostone-hosted hydrothermal polymetallic ore deposit, associated with
ludlockite, cuprian adamite,
stranskiite and tsumcorite (HOM).
At the type locality, the Tsumeb Mine, Oshikoto Region, Namibia, warikhanite occurs in the second oxidation zone on corroded tennantite associated with adamite, stranskiite, koritnigite, claudetite, tsumcorite and ludlockite (Dana, AM 65.408). The first specimen found was at the E9 pillar, associated with cuprian adamite, koritnigite, stranskiite, helmutwinklerite, claudetite, ludlockite, tsumcorite and lavendulan; a later find was a specimen from the O stope, 31 level, where the only associated mineral was quartz (MinRec 36.4.315).
