“…In coal seams or other sedimentary strata, the ratio of TiO 2 /Al 2 O 3 is considered to be an important parameter, , and it is also a sign to identify the type of volcanic ash in coal and coal-measure strata . Successive researchers, such as Addsion, Hayashi et al, and Bueger et al, agreed that the ratio of TiO 2 /Al 2 O 3 in acidic pozzolans is less than 0.02 and that, in alkaline pozzolans between 0.02 and 0.08, the ratio of basic volcanic rocks is greater than 0.08.…”

“…In fact, the previous geological results indicate that, in the lithology composition of the coal-bearing rock series in the Bijie area, in addition to clastic rocks, argillaceous rocks, carbonate rocks, etc., there is indeed a small amount of volcanic clastic rocks. 47,48,53 In coal seams or other sedimentary strata, the ratio of TiO 2 / Al 2 O 3 is considered to be an important parameter, 54,55 and it is also a sign to identify the type of volcanic ash in coal and coalmeasure strata. 47 Successive researchers, such as Addsion, 56 Hayashi et al, 57 and Bueger et al, 58 agreed that the ratio of TiO 2 /Al 2 O 3 in acidic pozzolans is less than 0.02 and that, in alkaline pozzolans between 0.02 and 0.08, the ratio of basic volcanic rocks is greater than 0.08.…”

Research on the enrichment mechanism of lithium in coal can increase its economic value. We applied a series of techniques such as X-ray diffraction and ICP-MS to analyze the coal samples collected in the Bijie area and studied the enrichment mechanism of lithium in coal based on the theory of mineralogy and sedimentology. The results show that (1) the highest abundance of lithium in coal is 222 μg/g, the lowest 33.2 μg/g, and the average 87.05 μg/g. Among them, the abundance of lithium in coal samples from Xinhua coalfield and Wenjiaba coalfield reached 136 and 222 μg/g, respectively, which reached the minimum industrial grade (120 μg/g). (2) Lithium in coal was positively correlated not only with ash (0.46) and clay minerals (0.41) but also with total organic matter (0.38) and volatile matter (0.58) in coal, indicating that lithium in coal in the Bijie area has both inorganic and organic origins. (3) The ratio of TiO 2 /Al 2 O 3 , a geochemical index, shows that the maximum ratio is 0.37, and the average is 0.09, indicating that the metal elements are a product of volcanic eruption, and the paleogeographic environment also shows that igneous rocks are exposed in the western provenance area of this study area. (4) The enrichment of lithium in coal is not closely related to the pure marine environment but is closely related to the marine–land transitional environment. In the past, there was a lack of relevant research on lithium in coal in the Bijie area, and the proposal of organic and inorganic coupling causes is of great significance for the development and utilization of lithium in coal.

“…There are still two problems to be solved about coal geochemistry in the Hegang coalfield: (1) did the volcanic activity influence the element enrichment in the coals? (2) The occurrence modes and the provenance of elements in the Palaeogene coal-bearing seams have been deeply studied recently in Jilin province [33][34][35][36], neighboring the Heilongjiang province. Is the provenance of trace elements in Hegang coals the same as in the coals from Jilin Province [33,35]?…”

Hegang coalfield is one of the areas with abundant coal resources in Heilongjiang Province. Characteristics of minerals and geochemistry of No. 26 coal (lower Cretaceous coals) from Junde mine, Hegang coalfield, Heilongjiang province, China, were reported. The results showed that No. 26 coal of Junde mine is slightly enriched in Cs, Pb, and Zr compared with world coals. The minerals in No. 26 coal of Junde mine primarily include clay minerals and quartz, followed by calcite, siderite, pyrite, monazite, and zircon. The diagrams of Al2O3–TiO2, Zr/Sc–Th/Sc, Al2O3/TiO2–Sr/Y, and Al2O3/TiO2–La/Yb indicate that the enriched elements in No. 26 coal were mainly sourced from the Late Paleozoic meta-igneous rocks in Jiamusi block. The volcanic ash contribution to No. 26 coal seems very low. Sulfate sulfur indicating oxidation/evaporation gradually decreases during No. 26 coal formation.

“…Many researchers [6, 7, etc.] noted the ore-controlling role of faults. However, there is an alternative recent hypothesis on hydrogenous and clastogene genesis of coal mineralization in coals of the Rakovka depression associated with granites of the Pre-Cenozoic basement and framing of the depression which is receiving more and more evidence [8,9].…”

The work deals with the role of Paleozoic granites as possible sources of metals in coals. The process of dissolution and transfer of metals in the system “granite-water” was modeled. It is shown that the scale of accumulation of ore matter in water depends on the duration of interaction between water and rock. As a result of physical and chemical modeling, the probable set of migration forms of components and their transformations were calculated. The results of modeling indicate in favor of the assumption that the studied leucocratic granites of the pre-Cenozoic basement could be a source of metals concentrated in the coals of the Rakovka depression.
