- •
Lithophile elements Be, Y, Nb, Zr, Hf, and U are enriched in the Guxu coal.
- •
The terrigenous-source rocks for the coal are mainly of felsic–intermediate composition.
- •
The lower part of the floor strata are a mafic tuff.
- •
The terrigenous-source region for the upper part of the floor rock has a felsic–intermediate composition.
- •
The coal and the floor strata are potential sources of rare metals.
