On concretions in the coal-bearing strata of the Tkvarcheli deposit
Authors:
Abstract
Concretion formations in coal-bearing strata have attracted the attention of lithologists in recent years as a phenomenon that facilitates facies analysis and reproduction of the formation environment of coal-bearing sediments. In the practice of studying coal basins, examples of the use of concretions as features for stratigraphic subdivision of coal-bearing strata and synonymy of coal seams are already known. In this regard, the concretions of the coal-bearing strata of the Tkvarcheli deposit are also of interest, a brief description of which is given in this note based on the results of the author's study of samples collected in 1949.
