1)Magmatic rare earth deposits
1)REE-P-Nb-Ta-Y-F-(Be-Zr-Th) deposits related to carbonatites
2)REE-P-Ti deposits related toalkaline igneous complexes
3)REE-U-Nb-bearing pegmatites (in places, transitional into intragranitic deposits with Mo-W-U-Be)
4)REE-Nb-P-F- bearinghydrothermal iron deposits
5)Be- and Y-bearing alkaline intrusive rocks (nepheline syenite)
2)Structure-related rare earth deposits
1)REE-F-Ba-Th- bearing vein-type deposits
3)Sedimentary rare earth deposits
1)REE-(Ti-P-Nb) residual deposits / placers on alkaline igneous and carbonatite complexes
2)REE in bauxite
3)Alluvial- to coastal REE placers
4)REE-bearing phosphorites
5)Ion adsorption clays
6)REE-bearing coals
The lion share of REE lies within the magmatic deposits and the ion adsorption clays but the bigger the hunger for REE the more the other REE accumulations get into the spotlight of exploraton geologists and economists
