The Stratigraphic Significance of Water Geochemistry
- 76 Downloads
The separation of water bodies and the correlation of water quality with stratigraphy in the central part of the Pannonian Basin are discussed. High Cl−, and a Cl−/Br− ratio similar to that of seawater, characterize the Pannonian sediments. More positive δ18O and δ2H values together with high K+ and Li+ concentrations delineate the location of the Pontian, whereas more negative δ values with low K+ and Li+ indicate the Pliocene. Increasing Na+ and decreasing Ca2+ and Mg2+ along the flow path are characteristic of the aquifers in the Pleistocene layers.
