Rare Earth Element Ore Geology Of Carbonatites. The rare earth elements (ree) have attracted much attention in recent years, being viewed as critical metals because of china's domination of their s. Although rare earth elements are relatively abundant in the earth's crust, they are rarely concentrated into mineable ore deposits.
Carbonatites are a relatively rare type of igneous rock composed of greater than 50 vol % primary carbonate minerals.
Ree mineralization occurs in hydrothermal assemblages within or near carbonatites, suggesting aqueous transport of ree. M28 rare earth elements host rocks include carbonatite, dolomite breccia with syenite intrusives, pegmatite and amphibole rare earths — south australia. Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals.
