Localities
At the Gigante pegmatite, Candelaria District, Cruz del Eje department, Córdoba Province, Argentina, carlhintzeite
occurs as colourless prismatic crystals up to 0.8 mm long, ubiquitously twinned on {001}
(MM 74: 623-632).
The type locality is the Hagendorf South Pegmatite, Hagendorf, Waidhaus, Neustadt an der Waldnaab District, Upper
Palatinate, Bavaria, Germany. On the type specimen, carlhintzeite is associated with
rockbridgeite, pyrite,
strengite and apatite; it is a
late-stage mineral formed after rockbridgeite,
pyrite and strengite, during the
hydrothermal alteration of primary
triphylite, the precursor of the
secondary phosphate minerals
(CM 17.103-105).
The carlhintzeite occurs in the granite
pegmatite as small white bladed crystals in open radial
clusters
(Mindat).
