General Notes
Keller and Bartelke (1982; citing Schnorrer-Köhler, 1980) report small cubic crystals of maghemite in association with duftite and willemite, implicitly (in the context of their article) from the second oxidation zone.
According to Gebhard (1999) a single specimen with sub-mm crystals - presumably the one alluded to by Keller and Bartelke (1982) - is the only known example with crystallised maghemite from Tsumeb.
