Field trip 3: The Lower Palaeozoic Gas Shales of Scania, Southernmost Sweden 

Friday, 15 June 2018, 08:00 - 18:00 hrs

Field trip leaders: A.T. Nielsen (University of Copenhagen) & N.H. Schovsbo (Geological Survey of Denmark and Greenland)

Field trip description

The aim of the field excursion is to demonstrate the c. 2 km thick Lower Palaeozoic succession of Scania, southernmost Sweden. It comprises a c. 150 m thick Lower Cambrian sandstone dominated sequence overlain by Middle Cambrian-Early Ordovician organic rich shales, the Alum Shale Fm. This unit is up to c. 100 m thick and has been the primary unit in focus in connection with shale-gas exploration in Denmark and southern Sweden.

Above follows a thick coarsening-upward package of Early Ordovician-Late Silurian shales and siltstones, with sandstones and limestones near the top. The TOC content is lower than in the Alum Shale Fm, but some intervals of the Ordovician-Silurian shales may also have potential for shale-gas exploration in Denmark and Sweden. The Lower Palaeozoic succession reflects fairly high sedimentary supply during the Early Cambrian transgression, strong sedimentary starvation during the Mid Cambrian-Ordovician sea level highstand and rapid sedimentation during the Silurian, where the area constituted a Caledonian foreland basin. The Cambrian-Ordovician shales exposed in Scania are stratigraphical equivalent to shales in northern Poland that also have been targeted for shales gas.

 

Important note: You are required to bring your passport along with you, as the field trip will take you into Sweden.
