NEW DATA ON HYDROGEOCHEMISTRY OF THE MINERAL WATERS OF THE CRIMEAN PENINSULA
Relevant data on the composition of mineral waters from 23 deposits and occurrences in the Crimean Peninsula are presented. The characteristic of 7 occurrences that have been previously unknown is presented. The studied waters are distinguished by broad-range variations in chemical composition, geochemical parameters of the medium, and the concentrations of biologically active components. Waters with the composition SO4-Cl-HCO3 Na, Cl Na, SO4-HCO3 Mg-Ca-Na, SO4-Cl Mg-Nam with TDS from ultra-fresh to brine level (0.4 - 202.9 g/dm3) are dominating. The waters relate to two large groups according to the geochemical parameters of the medium. The first group is characterized by reductive conditions with Eh from -330.2 to -22.3, pH from 7.3 to 9.1 and O2dissolved concentration 0.79 - 6.48 mg/dm3. The second group is characterized by oxidative Eh (+22.1 - +158.5), neutral and weakly alkaline pH (7,0 - 8,4), and O2dissolved concentrations from 2.73 to 6.92 mg/dm3. The studied waters exhibit a broad range of balneological properties, which allowed us to distinguish 13 types of mineral waters.
