Allanite and Other REE-Rich Epidote-Group Minerals
Reviews in Mineralogy and Geochemistry, 2004Epidote-group minerals rich in rare earth elements (REE), in particular allanite, are common accessory phases in igneous, metamorphic, metasomatic, and sedimentary rocks. Small amounts of REE are present in most epidote-group minerals, but in allanite—and the related minerals dissakisite, ferriallanite, dollaseite, khristovite and androsite—the REE are

The Bayan Obo REE-Nb-Fe deposit hosts the world’s largest known REE resource. The deposit consists of replacement bodies hosted in dolomite marble made up of magnetite, REE fluorocarbonates, fluorite, aegirine, amphibole, calcite and barite. Three types of fluid inclusions have been recognized: two phase aqueous liquid-apor (L-V), two to three phase ...

Petrochronology Based on REE-Minerals: Monazite, Allanite, Xenotime, Apatite
Reviews in Mineralogy and Geochemistry, 2017### REE-minerals Monazite, xenotime, and allanite are REE1-minerals sensu stricto because lanthanides (La…Lu) and yttrium are critical constituents in them. Apatite does not require REE, but because it contains substantial REE in many rocks, it is included in this review.

Some of the world’s largest REE deposits were formed via secondary hydrothermal fluid enrichment. REE-bearing minerals of economic interest precipitate in these environments from the interactions of the hydrothermal fluid and the surrounding wall-rock. This interaction dissolves part of the wall-rock to release ions which combine with the REE complexes
