This paper investigates the mineralogical and geochemical compositions of the Late Permian coals in the Liulong Mine, Liuzhi Coalfield, Western Guizhou Province, China, by using XRD, SEM-EDX, ICP-AES and ICP-MS. Both the No.3 and No.7 Coals are classified as low volatile bituminous coal. However, the No.3 Coal is a medium-ash (29.8% on average) and high-sulfur (4.76% on average) coal while the No.7 Coal is a low-ash (12.4% on average) and medium-sulfur (2.16% on average) coal. Major minerals in both coal seams include quartz, pyrite, marcasite, kaolinite, calcite, and to a lesser extent, gypsum and anatase. Illite, chlorite, rectorite, albite, ankerite and siderotil are only present in the No.3 Coal. The No.3 Coal contains higher elemental concentrations than the No.7 Coal probably due to the higher mineral contents in the No.3 Coal, and is enriched in Nb and Ta, and to a lesser extent in K, Ti, Li, V, Co, Cu, Sr, Zr, Mo and Ba.
