LITHOLOGY AND HYDROCHEMICAL
FEATURES OF THE GEOENVIRONMENT
OF THE DNISTER KARST REGION

This study examines the lithological structure and hydrochemistry of the geological environment in the
Dniester sulfate karst region of Podillia, located within the Ternopil region. It highlights that easily soluble sulfate rocks, primarily gypsum and anhydrite, are situated near the surface and are subject to
active karst formation. This process is intensified by the region’s favorable geological, tectonic structures and climatic conditions. Recently, the rate of karst formation has increased due to the growing
open-pit mining activities targeting gypsum and anhydrite rocks in the area. As a result, new cavities,
ravines, channels, and minimally mineralized lakes are forming, disrupting normal groundwater flow
and compromising the integrity of the Neogene aquifer. Additionally, the processes of soil salinization
surrounding mining sites are becoming more pronounced. To manage the geological environment
effectively, it is recommended to conduct systematic monitoring studies. 

Keywords: lithogenesis, hydrochemistry, gypsum-anhydrite rocks, geological environment, Dniester
