Boron, fluoride, strontium and lithium anomalies in fresh groundwater of Lithuania
Algirdas KLIMAS, Algirdas MALIŠAUSKAS
Anomalies of certain trace elements most typical of salt water sometimes occur in fresh groundwater aquifers. For example, it is a well-known fact that Permian–Devonian aquifers contain increased concentrations of fluoride in West Lithuania. In the recent years, increased concentrations of boron and strontium have also been found there. An analysis of available data shows that natural anomalies of B, F, Sr and perhaps Li interrelate with fresh–salt water transit zones where groundwater circulates in fine-grained clayey sand or in fissured beds of limestone, dolomite or gypsum deposited in marginal parts of high salinity basins.
