A Geochemical Study of an REE‐rich Carbonatite Dyke at ...

 · Abstract An REE‐rich carbonatite dyke was found in Dulahala, close to the Bayan Obo superlarge REE‐Nb‐Fe mineral deposit in Inner Mongolia, northern China. The REE content in the dyke varies greatly, from 1% up to 20% (wt), which might constitute rich REE ores. Light REEs in the carbonatite are enriched and highly fractionated relative to heavy REEs and there is no Eu anomaly. .
