This study investigates the mineralogical characteristics of No. 3 coal seam in the Mahuangliang Coal Mine, located within the Jurassic coalfield of northern Shaanxi Province, China. Utilizing techniques such as low-temperature ashing (LTA), X-ray diffraction (XRD), scanning electron microscopy with energy- permissive spectroscopy (SEM-EDS), and Siroquant software, we examined the distribution and composition of the minerals present in the coal, partings, and roof and floor strata. The results reveal a rich assemblage of minerals, including quartz, kaolinite, and carbonates. The primary geological factors controlling the distribution of minerals and trace elements are the input of detrital materials from the depositional source area and the influence of hydrothermal fluids.
