Varying pressures of the ice sheets as a factor of the Pleistocene activity of the Polotsk-Kurzeme and the Smaland-Blekinge deformation zones

Topographical maps, airphotos and satellite images suggest a remarkable linear arrangement of landforms here called lineaments. Those lineaments are often related to fault zones of the crystalline basement. A good example of this relationship is the Polotsk-Kurzeme Deformation Zone (PKDZ) nd its possible continuation across the Baltic Sea into the Småland-Blekinge Deformation Zone (SBDZ) and Bornholm Island. The influence of Mesoproterozoic faulting on the Paleozoic, Mesozoic, Cenozoic and recent evolutions of the Precambrian crust has been assessed using 3D reconstructions of paleosurfaces, GIS (=Geographical Information Systems) -models of basement-cover correlation and topolineaments identification. The key target areas of this study have been the Polotsk part of the PKDZ in northern Belarus and the eastern part of the SBDZ in southeastern Sweden. As a result of the study, two main stages of activity of the PKDZ have been identified in the Polotsk area. In the Mesoproterozoic, the major EW- and linked NS-trending fault systems developed in conjunction with orogenic processes at the southwestern margin of the EEC. In the Cenozoic, the activity of this belt was caused by both neotectonics and varying pressures of the ice sheets with attendant Pleistocene deformation of the sedimentary cover within the Polotsk area. In the eastern part of the SBDZ key area the Mesoproterozoic-Phanerozoic activity has been identified

A GIS-model of the basement-cover correlation in the Poozerye area of the Polotsk-Kurzeme fault belt in Belarus

The main aim of this study is to correlate geological surfaces of various ages and the present-day landforms above the Polotsk-Kurzeme zone. The instrument of the study has been the geographical information systems (GIS), which allows to visualize the landforms and various structural surfaces, as well as to compile maps of correlation coefficients between these features. The key area of this study is the Poozerye area in the Polotsk-Kurzeme fault belt in Belarus

The Polotsk-Kurzeme and the Småland-Blekinge Deformation Zones of the East European Craton : geomorphology, architecture of the sedimentary cover and the crystalline basement

This is a study of the influence of the crystalline basement faults of the Polotsk-Kurzeme and the Småland-Blekinge Deformation Zones on the development of the sedimentary cover and the formation of the present topography. The purpose is to define the character and possible causes of this influence. The key target areas of this study are the Polotsk part of the Polotsk-Kurzeme Deformation Zone in northern Belarus and the eastern part of the Småland-Blekinge Deformation Zone in southeastern Sweden. The influence of Mesoproterozoic faulting on the Paleozoic, Mesozoic, Cenozoic and recent evolutions of the Precambrian crust has been assessed using 3D reconstructions of paleosurfaces, GIS (=Geographical Information Systems) models of basement-cover correlation and topolineaments identification. The 3D upper paleosurfaces of the crystalline basement, the Ectasian-Stenian, Ediacaran, Ordovician, Devonian and Quaternary sedimentary deposits and the present landform surface for the Polotsk key area as well as the 3D upper paleosurfaces of the crystalline basement and the present landform surface for the eastern part of the SBDZ key area have been performed with ArcGis 9.1 software. A series of maps showing correlation coefficients between the upper paleosurface of the crystalline basement and all the various Phanerozoic deposits has been produced for the key target areas. We have also profiled the Quaternary deposits in the Polotsk area. The results suggest that these deformation zones, after their first formation in the Mesoproterozoic in conjunction with orogenic processes at the southwestern margin of the East European Craton were still active during the Neoproterozoic- Phanerozoic. The tectonic activity of the Polotsk-Kurzeme and the Småland-Blekinge Deformation Zones has had influence both on the formation of the sedimentary cover and the present topography.Denna undersökning rör frågan om vilket inflytande förkastningarna i de tektoniska Polotsk- Kurzeme och Småland-Blekingezonerna utövat på det överlagrande sedimenttäckets och den nutida topografins utbildning. Syftet var att bestämma karaktären av denna påverkan och dess tänkbara orsaker. De huvudsakliga undersökningsområdena utgjordes av Polotskdelen av Polotsk-Kurzeme deformationszonen i norra Vitryssland och östra delen av Småland-Blekingezonen i sydöstra Sverige. Den mesoproterozoiska förkastningsaktivitetens inverkan på den paleozoiska, mesozoiska, kenozoiska samt recenta utvecklingen av den prekambriska jordskorpan fastställdes med hjälp av 3-D rekonstruktioner av paleoytornas lägen och GIS-modellering av topolineament och relationerna mellan underlag och sedimenttäcke. ArcGis 9.1 mjukvaran användes för att fastställa 3-D övre paleoytor for det kristallina underlaget, de ektasisk-steniska, ediakariska, ordoviciska, devonska och kvartära avlagringarna och den nutida jordytan i Polotskområdet samt den 3-D övre paleoytan för det kristallina underlaget och dagens landyta i östra delen av Småland-Blekingezonen. Dessutom sammanställdes en serie kartor som visar korrelationskoefficienterna mellan det kristallina underlagets paleoyta och alla de andra övre gränsytorna för de fanerozoiskasedimenten i de två huvudsakliga undersökningsområdena. Profilering av de kvartära avlagringarna utfördes i Polotskområdet. Resultaten visar att deformationszonerna efter sin bildning i samband med mesoproterozoiska orogena processer vid den östeuropeiska kratonens sydvästkant fortsatte att vara aktiva även under neoproterozoikum och fanerozoikum. Den tektoniska verksamheten inom Polotsk-Kurzeme och Småland-Blekinge deformationszonerna påverkade såväl sedimenttäckets bildning som den nutida topografin
