Petrographic characterization of Tertiary brown coals of the Babaevskoe and other deposits of the Southwestern Urals region
Abstract
Low-metamorphosed brown coals of Tertiary age, widely distributed within the right-bank Ukraine, southwestern Urals and northern Kazakhstan are insufficiently investigated from the petrographic side . There is still no well-developed methodology for studying low-metamorphosed loose brown coals, which differ sharply from denser brown and hard coals, as well as from peats. In the present article, the results of complex (botanical, petrographic and chemical) study of the material composition of low-metamorphosed brown coals composing a thick seam of the Babaevskoe deposit are presented and their comparison with coals of other Tertiary deposits of the southwestern Urals is given. The questions of the origin of low-metamorphosed brown coals are considered by the author in a special article; a detailed characterization of the types of coals and the structure of coal deposits of individual deposits of the South Ural brown-coal basin is set forth in the atlas currently being prepared.
