The processes affecting the formation of the chemical composition of the waters take place in specific hydrochemical zones. The knowledge of such phenomena allows to draw conclusions regarding the origin and conditions prevailing in the regions of their occurrence, e.g. indicate a zone of active water exchange, i.e. an inflow of infiltration waters, or a zone of isolated geological structures, where diagenesis processes take place. The aim of the study was to assess the hydrochemical conditions which affect the formation of chemical composition and genesis of origin of sulfide waters from the Busko-Zdrój and Solec-Zdrój region (Poland) using selected hydrochemical indices (rNa⁺/rCl⁻, rNa⁺/rK⁺, rNa⁺/(rNa⁺+rCl⁻), rSO₄²⁻ × 100/rCl⁻, rCl⁻/rBr⁻, rHCO₃⁻/rCl⁻ and the weight index: Cl⁻/Br⁻). A detailed analysis was carried out for sulfide waters from fifteen intakes and five springs. Several aquifer systems are found in the study area. Investigated intakes and springs differ in terms of stratigraphy and lithology. The analysis of changes in the values of selected hydrochemical indices confirms that waters of the Busko-Zdrój and Solec-Zdrój region belong to two systems of circulation — “shallow” and “deep”. The formation of the chemical composition of analysed waters occurs mainly in the aquifer. The values of rNa⁺/rCl⁻, rCl⁻/rBr⁻, rNa⁺/(rNa⁺+rCl⁻), and Cl⁻/Br⁻ indices suggest that the salinity of sulfide waters may result from leaching of salt interburdens and inclusions. In the area of occurrence of sulfide springs, tectonic cracking zones enable the inflow of highly mineralized waters and thus contribute to the mixing of waters of different aquifers. High content of Cl⁻ and Na⁺ ions as well as mineralization higher than in sea waters indicate the formation of waters from the upper Cretaceous level together with deposits in a sedimentary basin.

影响水域化学成分形成的过程发生在特定的水化学区。对此类现象的了解可以得出关于其发生区域中普遍存在的起源和条件的结论，例如，指示成岩作用发生的活跃的水交换区（即入渗水流入）或孤立的地质结构区。地点。该研究的目的是评估使用选择的水化学指数影响的化学组成，并从布斯科兹德鲁伊和索莱克-特洛伊区域（波兰）硫化物水域的起源的成因形成的水化学条件（RNA ⁺ / RCL ^-，RNA ⁺ / rK ⁺，rNa ⁺ /（rNa⁺ + RCL ^-），RSO ₄ ^2-  ×100 / RCL ^-，RCL ^- / RBR ^-，RHCO ₃ ^- / RCL ^-和配重指数值：Cl ^- /溴^-）。对15个进水口和5个泉水中的硫化物水进行了详细分析。研究区域发现了几种含水层系统。研究的入口和泉水在地层和岩性方面有所不同。对所选水化学指标值变化的分析证实，布斯科-兹德鲁伊和索莱茨-兹德鲁伊地区的水属于“浅”和“深”两个环流系统。被分析水的化学成分的形成主要发生在含水层中。RNA的值⁺ / RCL ^-，RCL ^- / RBR ^-，RNA ⁺ /（RNA ⁺ + RCL ^-），和Cl ^- /溴^-指数表明，硫化物水的盐度可能是盐分岩和包裹体浸出的结果。在发生硫化物泉水的地区，构造裂缝带使高矿化水流入，从而有助于混合不同含水层的水。氯含量高^-和Na ⁺离子以及矿化比海水更高表明水域从上部白垩纪水平形成在沉积盆地沉积在一起。
