HRTEM study of recrystallization mechanisms in metamict allanite

2014
Allanite is a sorosilicate with general formula CaREEAlAlFe2+[SiO4|Si2O7]O(OH) where REE = Ce, La, Nd, Y, but Th and U (in small amounts ~1 wt. %) can substitute for REE. Rather complex crystal structure and chemical composition along with the radioactive decay of, most notably, Th cause the allanite crystal structure to become metamict i.e. amorphous.
