Abstract

COMMENCEMENT OF UPPER CRETACEOUS TRANSGRESSION IN POLAND (without Carpathians and Silesia)In the post-Neocomian period, during the Aptian or maybe already during the Barremian and during the Albian, the area of the present-day Kujavian - Pomeranian arch rand of the northern part of the margin of the Święty Krzyż Mountains undergoes subsidence. There is being formed a fresh-water basin (lake) in which arenaceous deposits are laid down. In the region of the Danish islands this basin lacks a connection with the open sea. During the Middle Albian a marine transgression sets in; the sea invades the area of a developing furrow (lake). In Poland, the Middle Albian is represented solely by arenaceous deposits (sands and sandstones), frequently containing glauconite and phosphoritic concretions. In the Upper Albian this transgression spreads.
