REE MINERALS OF PHYLLITES OF THE MAIN CENTRAL THRUST OF THE TAMOR WINDOW AREA, EASTERN NEPAL
A sample of chlorite-muscovite fillite metamorphosed under greenschist facies of metamorphism 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 allanite, monazite and xenotime....

| Summary: | A sample of chlorite-muscovite fillite metamorphosed under greenschist facies of metamorphism 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 allanite, monazite and xenotime. The temperature of their formation based on chlorite thermometer and mineral assemblages is below 410 °С. The clayey minerals and biogenic calcium phosphate from primary pelite rocks are suggested to be the source for REEs. |
