文摘
- •
The Coal is characterized by highly-elevated concentrations of U-Re-V-Cr-Se.
- •
Roscoelite was formed by interaction between U-Re-V-Cr-Se-rich solutions with kaolinite.
- •
Tobelite was formed by reaction between kaolinite and NH4 +.
- •
The mafic tuffs served as the sediment source of the coal.
- •
The highly-elevated REE is attributed to the input of hydrothermal solutions.
