Fig. 6. REE-bearing mineral occurrence of tuffaceous coal deposits. (A)-(F) Kaolinite and quartz are working as major matrix minerals, with secondary anatase, silicorhabdophane and florencite. Detrital minerals originated from tuff layers and authigenic secondary minerals occur together (Figure replicated with permission from Elsevier and Rightslink. Dai et al., 2014).
