Place of Conservation of Type Material:
Geological Scientific Museum of the Satpaev Institute of Geological Sciences, Almaty, Kazakhstan: registration number 3010.
Geological Setting of Type Material:
In a rare-element deposit, which is spatially related to
two small oval outcrops of alkaline granite.
