The Jurassic of Skåne, Southern Sweden

Ahlberg, Anders LU ; Sivhed, Ulf and Erlström, Mikael (2003) In Geological Survey of Denmark and Greenland Bulletin 1. p.527-541
Abstract
In Sweden, Jurassic strata are restricted to Skåne and adjacent offshore areas. Jurassic sedimentary

rocks predominantly comprise sandy to muddy siliciclastics, with subordinate coal beds and

few carbonate-rich beds. During Mesozoic times, block-faulting took place in the Sorgenfrei–

Tornquist Zone, a tectonic zone which transects Skåne in a NW–SE direction. The Jurassic depositional

environments in Skåne were thus strongly influenced by uplift and downfaulting, and to

some extent by volcanism. Consequently, the sedimentary record reveals evidence of numerous

transgressions, regressions and breaks in sedimentation. Relative sea-level changes played a significant

role in... (More)
In Sweden, Jurassic strata are restricted to Skåne and adjacent offshore areas. Jurassic sedimentary

rocks predominantly comprise sandy to muddy siliciclastics, with subordinate coal beds and

few carbonate-rich beds. During Mesozoic times, block-faulting took place in the Sorgenfrei–

Tornquist Zone, a tectonic zone which transects Skåne in a NW–SE direction. The Jurassic depositional

environments in Skåne were thus strongly influenced by uplift and downfaulting, and to

some extent by volcanism. Consequently, the sedimentary record reveals evidence of numerous

transgressions, regressions and breaks in sedimentation. Relative sea-level changes played a significant

role in controlling the facies distribution, as deposition mainly took place in coastal plain

to shallow shelf environments.

The alluvial deposits in Skåne include floodplain palaeosols, autochthonous coals, overbank

sandstones, and stream channel pebbly sandstones. Restricted marine strata comprise intertidal

heteroliths with mixed freshwater and marine trace fossil assemblages, and intertidal delta distributary

channel sandstones. Shallow marine sediments encompass subtidal and shoreface sandstones

with herringbone structures, and bioturbated mudstones with tempestite sandstones.

Offshore deposits typically comprise extensively bioturbated muddy sandstones.

Floral remains, palaeopedology, clay mineralogy and arenite maturity indicate a warm and

humid climate in Skåne throughout the Jurassic, possibly with slightly increasing aridity towards

the end of the period. Most Jurassic strata in Skåne have been subjected to mild burial diagenesis,

and the petroleum generative window has rarely been reached. (Less)
