Abstract - Summary 
(short description):
The results of a comparative mineralogical analysis of monazites from the biotite granites and leucogranites of Severny pluton (Chukotka) are presented. The average chemical formula of the monazites is Ce0.51La0.19Nd0.15Sm0.01Gd0.02Th0.07U0.01Ca0.04)PO4 and the composition doesn’t differ significantly between granite types. Several generations of monazite are observed. The total content of monazite is decreased in zinnwaldite-bearing granites.
