High-chlorine coal (salt coal) is observed on all continents in coal-bearing sediments from the Carboniferous to the Neogene. In Ukraine high-chlorine coal is recorded in all coal-bearing basins. Its characteristic feature is the increased content of sodium and chlorine. The author adheres to the concept of salinization of coal organic matter in the stage of sedimentodiagenesis. The formation of high-chlorine coals is a natural consequence of certain conditions of the geological past of the Earth. In all know cases geo-ecological conditions of high-chlorine coal formation were determined by the presence of a salt source at the peat stage. Such a source in paralytic coal basins was sea water, in areas of development of halogenic formations — products of their decomposition, in active magmatism regions – derivatives of magmatic and postmagmatic activities. On the basis of the conception of sediment-diagenetic salinization of coals, a wide range of various geological tasks can be solved, such as recovery of paleogeographical conditions of peat accumulation, prognosis of content of high-chlorine coals in various regions or geological formations, correlation of geological events and specification of the history of geotectonic development of coal bearing basins, specification of salt balance of evaporitic basins and etc. The geological and epistemological aspects of the phenomenon of salt coal are of purely applied interest, because they are closely related to the technological tasks of its use. The question of the industrial use of high-chlorine coal can be solved already in the near future with the advent of effective technologies for its ground or underground processing.
