- •
The lower part of Xunwei Formation is extremely rich in rare earth and rare dispersion elements.
- •
REEs are mainly enriched in the kaolinite clayrocks and carbonaceous mudstone.
- •
The layer with ∑ REE > 1300 ppm is > 4 m thick and becomes “REE enriched layer”.
- •
The correlation between REE contents and mineralogy indicates REE as ion adsorption state mainly in clay minerals.
