Mokhonko V. Geochemistry of karst processes in conditions of groundwater technogenic pollution (by example geological structures Severskodonetskaya plains)

The thesis is devoted to the development of science-based approach to estimating the rate of karst formation and forecasting of the intensity of carbonation aggression of karst waters in technogenically loaded areas on the basis of studying the laws of development and factors enhancing chalk-marly karstogenesis. Regional and local factors and patterns of chalk-marly karst process on Severskodonetskaya plains are established. The kinetic parameters of dissolution of calcium carbonate are defined. The kinetic equations describing the mechanism of the process of dissolution of calcium carbonate in the conditions of chemical and thermal pollution of karst waters by waste production of soda ash are suggested. On the basis of the study and analysis of trends and factors of development of chalk-marly karst and experimental studies of the dissolution rate of calcium carbonate a method of estimation the intensity of the aggression of the carbonate karst water is suggested. The method allows predicting the velocity of the chalk-marly karstogenesis in areas with high technogenic load.
