Abstract
This literature study aims to summarize the Precambrian bedrock and its geological development in
northern Scania. The study is based on previously published material, primarily three of SGU’s bedrock maps: Af
127, 155 and 181. These show the bedrock in the area northeast, southwest and northwest of Kristianstad. In order
to place this bedrock in a broader context, other publications dealing with southern Sweden’s Precambrian bedrock
and its development have also been studied. The bedrock in northern Scania is very varied. The eastern part of the
map area belongs to a significant geological boundary zone, the traditionally called Protogine zone. The zone is
characterized by intrusions of dolerite and syenite. The bedrock west of the... (More)

characterized by intrusions of dolerite and syenite. The bedrock west of the zone is dominated by strongly deformed,
more or less migmatic gneisses. The bedrock east of the zone has not undergone such high-grade metamorphism
and penetrative deformation. The Precambrian bedrock around Kristianstad was formed in several stages,
where the latest metamorphism and ductile deformation took place around 980-920 million years ago during the
final phase of a large mountain building event, the Sveconorwegian orogeny. At that time, Scandinavia’s Precambrian
bedrock was a part of the former supercontinent Rodinia. (Less)

Denna litteraturstudie syftar till att sammanfatta den prekambriska berggrunden och dess geologiska
utveckling i norra Skåne. Studien bygger på tidigare publicerat material, primärt tre av SGU:s berggrundskartor:
Af 127, 155 och 181. Dessa visar berggrunden i området nordost, sydväst och nordväst om Kristianstad. För att
kunna sätta in denna berggrund i ett större sammanhang har även andra publikationer som behandlar södra Sveriges
prekambriska berggrund och dess utveckling studerats. Berggrunden i norra Skåne är mycket varierad. Östra delen
av kartområdet tillhör en markant geologisk gränszon, som traditionellt kallas protoginzonen. Zonen karaktäriseras
av branta stråk med nord-sydlig deformation samt linser med hyperitdiabas och... (More)

av branta stråk med nord-sydlig deformation samt linser med hyperitdiabas och syenit. Berggrunden väster om zonen
domineras av kraftigt deformerade och metamorfa gnejser. Berggrunden öster om zonen har inte genomgått
samma intensiva metamorfos och deformation. Den prekambriska berggrunden runt Kristianstad har bildats i flera
etapper, där den senaste metamorfosen ägde rum för cirka 980-920 miljoner år sedan i samband med slutskedet av
en stor bergskedjebildning, den svekonorvegiska orogenesen. Vid den tiden utgjorde Skandinaviens prekambriska
berggrund en del av den forna superkontinenten Rodinia. (Less)
