(a) Powder XRD patterns of FY-6, FG-3, FB-4 and FO-1 (scanning speed of 2°/min) exhibit the characteristic patterns of vesuvianite (ICDD PDF 89-5403). (b) The additional weak diffraction peaks at 2θ = ~12.46° for FB-4 and FO-1 were investigated with a more detailed stepping scanning mode XRD (at a scanning speed of 1 s/step and a step length of 0.02°), which indicated the presence of clinochlore. Ves = vesuvianite; Clc = clinochlore.
