Comments: | Dissakisite-(La) is in found REE nodules/pebbles a few cm in diameter and the individual minerals usually occur as patches or zones in the massive nodules. together with a series of other rare REE minerals, both Ce- and La-dominant. The photo shows dissakisite-(La) as the black rim associated with britholite-(Ce) outside a bastnasite-(La) monograin. The at this locality reach The locality is a placer deposit that has been worked for gold; the REE pebbles originate from a metasomatically influenced border zone of the Kyshtym Alkaline massif. | |||||||||||
