Paleośrodowiskowe zmiany w świetle analiz palinologicznych późnovistuliańskich osadów węglanowych w zagłębieniach bezodpływowych w Bełchatowie
The calcareous deposits in the upper part of Quaternary-age sediments were found in the Bełchatów mine. These deposits were accumulated in closed depressions. AIl these depressions are located in Świętojanka valley and tributary valleys (Fig. 1). The geological structure, chemical and mineral compos...
