Charakterystyka chemizmu osadów górnej kredy w Polsce (bez Karpat)

Abstract

CHARACTER OF CHEMICAL PROPERTIES OF THE UPPER CRETACEOUS DEPOSITS IN POLAND (EXCEPT FOR THE CARPATIDAN AREA)

The character of chemical properties of the Upper Cretaceous deposits occurring in Poland (except for the Carpathiain area) has been established on 3776 chemical analyses. The analyses were so selected that the results determine at least four chemical constituents as follows: CaO, MgO, SiO₂ and A₂O₃. The present author collected the material under study having in view the following aspects character of chemical properties of the deposits of the Upper Cretaceous (Figs. 1, 2,3, 4 and 5) and chartacter of chemical composition of the individual lithological rock types, taking also into account their percentage in the thickness of the individual stages (Tab. 1 and Fig. 7).
