Description | Allanite-(Ce) occurs in pyroxene (+/- garnet, plagioclase) skarn and in pegmatite dykes cutting regionally metamorphosed iron skarn body near Řešice. The results of microscopic study and microprobe analyses of allanite and its alteration products (parisite, thorogummite, Th-uraninite) are presented. The chemical compositions of allanite from skarn and pegmatite (allanite I and allanite II) are different, but predominate variations due to metamictisation and alteration. |
