It is delineated by the Caledonian orogen on the north-west, Variscan on the south, and by the margin of the Old Platform on the north-east. Poland is situated in its SE corner where the two latter features, Variscan orogen and the margin of the Old Platform, converge.

(7) The southern part of the basin was subjected to compression accompanied by horizontal shitting along faults at the end of the Mesozoic during the Laramie phase.

The translocations related to the movements in the Tethyan areas and the formation of the Atlantic rift west of Europe was SE-NW oriented. This was the end of the taphrogenic stage.

THE TECTONIC SETTING OF POLAND IN THE LIGHT OF THE STUDIES ON THE NORTH SEA AREA Summary The recent papers of P. A. Ziegler (1975) and W. H. Ziegler (1975) markedly contributed to the knowledge of geological evolution of the central and western Europe and thus, of the extra-Carpathian Poland. The main theses are as follows: (1) The metamorphic basement of the north-western Poland may be more reliably dated at the Dalslandian as the older basement of the neighbourhood of the southern North Sea was shown to be of that age.
