| Description | Alkaline metasomatites originated from granitoids of the Čistá-Jesenice Pluton contain a rich association of REE-bearing minerals. Whereas occurrence of REE carbonates (bastnäsite, parisite), monazite, rhabdophane, churchite, fergusonite and pyrochlore was found in relatively weakly altered rocks, much richer assemblage was observed in rocks which underwent the strongest metasomatism (so called reomorphic cancrinite-nepheline syenites). Here, the mineral assemblage contains also xenotime and REE silicates, including tritomite/melanocerite, allanite, perboeite, gadolinite and a Mn-analogue of hingganite. Cerium, yttrium, and to lesser extent also lanthanum are dominating cations in the studied REE phases. A total of 24 mineral species was identified, including three unnamed phases. |
