Occurrence and Geochemistry of REE Minerals From the Western Part of the Lugiin Gol Carbonatite Deposit, Southeast Mongolia

open access: yesResource Geology, Volume 76, Issue 1, January/December 2026.
The western Lugiin Gol REE deposit, related to the Lugiin Gol alkali intrusive complex, consists of carbonatites filling NE‐trending fractures in sedimentary rock. The carbonatites are dominated by carbonate minerals and fluorite and host REE fluorocarbonates, including synchysite‐(Ce), bastnaesite‐(Ce), parisite‐(Ce), and synchysite–bastnaesite ...
