Hydrothermal environments

Although cámaraite was approved in 2009, to date (May 2023) it has been reported only from the type locality.

Localities

At the type locality, the Verkhnee Espe Massif, Akzhaylyautas Mts, Tarbagatai Range, East Kazakhstan, cámaraite was found within a part of the deposit where alkali-rich fenites have been extensively recrystallized. Cámaraite is a hydrothermal mineral and occurs along with bafertisite, jinshajiangite, zircon, pyrochlore-group minerals, thorite, monazite-(Ce), xenotime and fluoro-leakeite as inclusions at the contact of the fenitised and granitised host rock. Cámaraite occurs on fracture surfaces, intergrown with jinshajiangite and bafertisite, and as star-shaped aggregates of orange-red to brownish red crystals (AM 95.1357-1358, HOM).
