Zarys stratygrafii pstrego piaskowca w skrajnie północnej Polsce

Anna Szyperko-Śliwczyńska



In the northern area of Poland the Buntsandstein deposits are as thick as from 300 m to 500 m, being developed in the facies analogical to that the Buntsandstein existing within the Lithuanian depression.
We find here series corresponding with both the Niemen and the Połąga series of the Wietługa stage (lower Buntsandstein). The Niemen series consists of siltstones, claystones and sandstones, brickred in colour, with more or less abundant calcareous interbeddings and intercalations of gypsum and anhydrite.
The Połąga series consists, in most its part, of red-brown siltstones with interbeddings of claystones and more or less abundant lenses and interbeddings of oolitic limestones. Intercalations of gypsum and anhydrite are also to be seen there; these latter are lacking only in the Gołdap vicinities. In all these bore-holes the topmost part of the Połąga series consists of alternating claystones and siltstones without the intercalations of anhydrite and calcareous interbeddings.
Everywhere, the Połąga series is overlain by that being differentiated in its development from the above mentioned Niemen and Połąga series and corresponding certainly with the middle Buntsandstein. I call this series the Warmia series. After sedimentation process of the Warmia series a durable interruption in deposition has taken place. At Lębork, the Buntsandstein deposits are overlain by Cretaceous sediments, at Bytów and Pasłęk by lower Keuper ones and at Bartoszyce and Gołdap by sediments of various Jurassic members.
