This page is currently not sponsored. Click here to sponsor this page.
Formula:
A2-mD2X6-wZ1-n
Hardness:
4½ - 5½
Name:
Name given for its content of lead, PLUMBum, and its relation to other "betafite" members of the pyrochlore group (sensu lato). Name first introduced by Ganzeev et al. (1969) for a mineral of the pyrochlore group (sensu lato) from the Burpala alkaline massif, Russia.
A variety of Pyrochlore Supergroup

Plumbobetafite of Ganzeev et al. (1969) is a Zero valent dominant member of the Pyrochlore Group. Plumbobetafite of Voloshin et al. (1993) is a "plumbobetafite".
