Determining the cause-and-effect relationships responsible for coal properties. 3. Association of chemical elements and role of indicators and accompanying elements in assessing the variability of beds’ mineral composition

详细

In the development of productive coal and oil beds, certain geochemical conditions facilitate the formation of elementary associations that include indicator elements and accompanying elements. The determination of those associations permits the identification of the features of mineral formation in the beds and the processes that affect the variability of the mineral composition in the intervening rock.
