“…Coals influenced by mafic volcanic ash input or by the input of detrital materials from mafic rocks in sediment-source regions are generally rich in transition elements or metals (e.g., V, Cr, Co, and Ni). Zhao et al calculated the Al 2 O 3 /TiO 2 ratios of samples from the Datanhao mine and found that a small number of samples are located in the mafic field, which likely explains the association of Co with Ni, and V with Cr in Figure .…”

“…Due to its high sensitivity, low detection limit, and broad linear range, inductively coupled plasma mass spectrometry (ICP-MS) has become one of the most competitive and promising methods for trace and ultratrace REE analysis in geological materials [7,[23][24][25] and is widely used in trace element testing compared to other analytical techniques like neutron activation analysis [26][27][28][29][30], X-ray fluorescence spectrometry [31][32][33], laser-induced breakdown spectrometry [34][35][36][37], atomic absorption spectroscopy [38][39][40][41], and inductively coupled plasma atomic emission spectrometry [42][43][44][45]. There have been many reports of concentrations of trace elements in coals that were successfully determined by ICP-MS [46][47][48][49][50][51][52]. However, the determination of Eu by ICP-MS is often interfered with due to the overlapping of M + , MO + , and MOH + ions [53][54][55], especially the polyatomic ions BaO and BaOH formed by Ba [20,22,56,57].…”

“…Coal-hosted critical metal elements are an important direction in the study of coal geology and mineral deposits. In recent years, researchers from the United States [7,8], Europe [9][10][11], Russia [12,13], South Africa [14] and China [15][16][17][18] have all conducted research in this field and achieved a set of high-level research results. The Qinshui coalfield is an important lean coal and anthracite base in Shanxi Province, and it is also one of the most important areas for coalbed methane exploration and exploitation.…”
