Peculiarities of the geological structure, rocks and coal quality of the Alkatvaam coal-bearing region of the Bering coal basin (new data)

The geological and tectonic structure of the Bering coal basin has been specified; a methodology for the preliminary determination of small-amplitude geological separations in coal seams was compiled; facies environments of coal formation are identified, described in detail and traced along the section; an assumption was made about the predominant role of thermal-regional metamorphism in the process of coal formation; the geochemical specialization of coals, as well as associated useful components that are potentially of industrial importance, have been preliminarily determined.
Keywords: hard coal, Bering coal basin, facies analysis, trace elements, coal metamorphism.
