Geochemistry of trace elements in coals from the Huainan Coalfield, Anhui, China

Abstract: With the aim of better understanding geochemistry of coal, 416 borehole samples of coal, one parting, two floor and two roof mudstones were collected from 9 minable coal seams in 24 boreholes drilled during exploration in the Huainan Coalfield, Anhui, China, and 47 elements were determined by various analytical techniques. The depositional environment, abundance, distribution, and affinity of elements were investigated. Results shown that the boron concentration in the coals indicates a brackish water depositi… Show more

“…This indicates the presence of mineral content in the form of irregularly shaped aggregates, where this bright light is due to the presence of calcium, aluminum, potassium, or sodium. In contrast, the dark part is primarily due to the presence of chalcophiles, the nonluminous part on the surface consists of carbon content (Yan et al, 2014). Chalcophile elements include Fe, S, and Ti (Kiseeva et al, 2017).…”
