Abstract
A sample of chlorite-muscovite fllite metamorphosed under greenschist facies of metamor-phism below biotite isograde of the Lower Himalayan Sequence from the Main Central Thrust zone of the Tamor tectonic window area (Eastern Nepal) are studied. The REE minerals are alla-nite, monazite and xenotime. The temperature of their formation based on chlorite thermometer and mineral assemblages is below 410 °C. The clayey minerals and biogenic calcium phosphate from primary pelite rocks are suggested to be the source for REEs.
