Opis:
Within the area of the Magura and Silesian units in the Polish Carpathians, 202 sites with carbonated waters and waters containing carbon dioxide have been recorded. They represent mainly mineral waters, in which the HCOexp.3– anion dominates, being occasionally accompanied by Cl–, and among cations Caexp.2+ and Mgexp.2+ prevail, occasionally accompanied by Naexp.+. Carbon dioxide is the specific component of all the waters, whereas in the waters with higher mineralization [i.e., higher TDS content] the specific components include also I, Br, B, Fe, occasionally H2S. The authors have divided the studied set of Carpathian waters applying the hierarchical and non-hierarchical classification algorithms (particularly the ISODATA algorithm) into five distinctly separated groups that can be accurately identified with linear discriminant functions.

Volhynian Polissia
Opis:
The post-glacial areas are characterized by favorable conditions for the formation of wetlands as a result of the widespread occurrence of depressions without outflow - center for the development of wetlands. The studies of morphogenetic conditions of the wetland development in Volhynian Polissia within the territory of Ukraine and the formation of their water regime reveal several features of their distribution and typological variety. The location of wetlands were characterized in reference to the shape of base/subsoil and its lithology. The typical structure of post-lacustrine, paludificational, riverside and spring peatlands of the Volhynian Polissia were shown and their development were also discussed. The wetland evolution under the influence of the postglacial landscape degradation leads to disappearance of the depression wetlands in glacial forms, increase of the peat bog trophicity and the level of peat dissolution. The supply conditions and characteristics of water regime are determined for separate peatlands. According to the origin and water flow/supply four types of wetland were extracted: ombrogenic, topogenic, soligenic and fluviogenic. It was found that the reasons of the high marshes areas (21%) in Volhynian Polissia are the geological and geomorphological conditions retaining/stopping the runoff and also local groundwater circulation system.
