Abstract
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)

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

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. (Less)
Abstract (Swedish)
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... (More)

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. (Less)
