Abstract


HYDROGEOCHEMISTRY OF THE UPPER TRIASSIC FORMATIONS IN THE WOŹNIKI AREA (BOREHOLE K-1)

Abstract. The investigations deal with Upper Triassic low permeability formations located in the Lubliniec–Myszków area of MGWB. The assessment of hydrogeochemical properties of these formations is a basis for determining their role in recharging groundwater of the Triassic carbonate aquifer and their influence on the groundwater chemistry. Drilling of the borehole K-1 (located in Woźniki) down to a depth of 99.5m made it possible to perform investigations on hydrogeochemical properties of the Upper Triassic formations (Norian-Rhaetian) composed mainly of clays, claystones and mudstones, locally interbedded by carbonates and sandstones. It was affirmed that the Upper Triassic interval contains two aquifers located in fissured claystones interbedded by carbonates and sandstones. This contribution presents the results of water content and porosity tests, water extracts from the Upper Triassic formations as well as chemistry and isotopic contents of the groundwater from these formations.
