Abstract

Targets of this study are to reveal the REE mineralization, and geochemical and geochronological characteristics of REE occurrences in north-west Mongolia; Ar gol, Alag erdene, Khujirtiin Davaa REE and alkali plutonic rocks in Bulgiin uvur and Suul tolgoi areas are also investigated. REE minerals of eudialyte, britholite, bastnasite, synchisite are found in Ar gol occurrence, only eudialyte mineral found from other two REE occurrences. Ar gol and Alag erdene REE occurrences reveal good potential for REE prospect criteria.
