Update of age data of the palvesk formation ("green wall") of Sambian peninsula (the Kaliningrad region)
... macro-faunistic characteristics, as well as the palynological complex according to previous studies. According to the results of absolute dating of glauconite isolated from the siltstones of the formation, as well as palynological data, it dates back to the Eocene age rather than the Oligocene (Ryupelian) as previously thought. This fact indicates that in the territory of the Kaliningrad Oblast, there may be no deposits of reliably Oligocene age, since it was only the palvesk formation which was thought ...
Geological conditions for submarine groundwater discharge in the South-Eastern Baltic
Submarine groundwater discharge is widespread in the Southern Baltic and creates specific conditions for the formation of benthic ecosystems. Groundwater has hydrochemical characteristics that are different from sea water, which is reflected in the chemical composition of bottom sediments and waters. In addition, underground runoff from the aquifers of the zone of active water exchange, along with river runoff and atmospheric deposition, can serve as a significant factor in the pollution of the marine...
