Environments
Whiteite-(CaMnFe) is a new mineral, approved in 2022 and to date (May 2023) reported only from the type
locality.
Localities
At the type locality, the Hagendorf South Pegmatite, Hagendorf, Waidhaus, Neustadt an der Waldnaab District, Upper
Palatinate, Bavaria, Germany, whiteite-(CaMnFe) was found in vugs in an altered
feldspar area of a specimen composed predominantly of
rockbridgeite, with
hureaulite and relic triphylite.
Other associated minerals in small vugs in the specimen were strengite and
laueite.
Whiteite-(CaMnFe) occurs as sprays and clusters of colourless to pale yellow, rod-like crystals, with diameters
of typically 10 to 50 µm and lengths up to about 500 µm
(EJM 35.95–103).
