“…A high proportion of calcareous rocks, including dolomites and Wesenberg limestone derived from the eastern part of the Baltic Sea Basin, with a modest share of red Ordovician limestones and a small quantity of sandstones that occur mainly in the western part of the Baltic Sea Basin and on the Swedish mainland (cf. Fredén, 1994;Smed, 2002;Šliaupa and Hoth, 2011), indicates the dominance of the eastern part of Fennoscandia and the Baltic Sea Basin as source areas of debris transported by ice. Similar conclusions can be drawn from an analysis of crystalline indicator erratics, which completely lack rocks from Bornholm and Skåne, while Småland erratics are represented in small quantities ( Fig.…”

The site at Orłowo Cliff was used to analyse the stratigraphic position and palaeogeographic interpretations of the properties and depositional conditions of two basal tills from the Late Pleistocene. A multi-proxy approach involved lithofacies, petrographic analysis of the fine gravel fraction, analyses of indicator erratics and till fabric. TL dating of intra-moraine deposits was used to determine depositional time frames of tills. The sediment profile at Orłowo Cliff shows a distinct reduction in number of Pleistocene units. Obtained dating results suggest the presence of Middle and Late Pleistocene fluvial units. The main issue discussed is the stratigraphic position of the older till (Unit O-4). It can be assumed that this till was deposited probably during the Middle Weichselian (MIS4). At Orłowo Horn the till of Unit O-4 reveals incorporation of the erratic material derived from an older till in the surrounded area (according to petrographic composition - probably from MIS 8). The younger till (Unit O-6) was deposited in the Late Weichselian (MIS 2). Moreover, the till of Unit O-6 is characterised by a significant shift towards the south-west in terms of the erratic origin in Unit O-4.

“…Possible reasons and time span causing these changes in the regional structural setting, and the role of the Baltic-Bothnian zone in it, are tied to a larger set of developments concerning the Cenozoic-Pleistocene tectonics, and the erosional and glacioisostatic history of Fennoscandia. The influence and mutual role of these factors in shaping the morphostructure on the southern slope of the Fennoscandian Shield, including the Baltic Sea depression and the klint-lines, are still widely disputed and ambiguously understood (Puura, 1991;Puura and Flodén, 1997;Šliaupa and Hoth, 2011).…”

Geo log i cal Quar terly, 61 (2): 396-412, doi: 10.7306/gq.1342Based on struc tural maps, the bed rock struc ture on the south ern slope of the Bal tic Shield is ana lysed. Gently south erly dipping (0.1-0.2°) Paleozoic lay ers from Es to nia to the Swed ish east coast form the Bal tic Homocline (BH). Nu mer ous monoclinal folds, forced by base ment fault ing, in duce slight vari a tions in bed rock at ti tude across the BH. Stud ies on faults ex posed in South ern Fin land sug gest that many monoclinal folds in duc ing base ment faults within the BH are of Pre cam brian or i gin and have been ac tive in pulses.

They both had an out let to the N-S-flow ing Eridanos River around the Gotska Sandön area, cre at ing thus two in de pend ent sec tions of the Bal tic Klint.
