Paleowaters in the Cambrian-Vendian (Ediacaran)aquifer system of Baltic Basin - isotopic and Geochemical evolution since Late Pleistocene

An overview of the status and origin of groundwaters in the Shallowly buried marginal part of the Cambrian-Vendian (Edicaran) confined aquifer of the Baltic Basin, which is characterised by fresh and isotopically depleted 18 δ O composition of water, whereas the deeply settled parts of the aquifer are characterized by typical Na-Ca-Cl basinal brines.
