Vulkanrester, Vik, Skåne - a photo on Flickriver

            The Central Skåne Volcanic Province was a site of volcanic activity in the Scania region of Sweden during the Mesozoic Era of the Earth's geological history. The volcanism began with a first and main phase in late Sinemurian–Toarcian times. Then volcanism continued sporadically for another 80 million years. More than one hundred volcanic necks of basaltic composition exist in Scania evidencing this volcanism. In central Scania, volcanism was in the form of a volcanic field of cinder cones that had strombolian eruption styles. These cones produced tuffite deposits made largely of lapilli with rare volcanic bombs. Pyroclastic materials were subsequently palagonitized or largely altered to clay minerals. While eruptions occurred on land the sea was likely very close to the area. Besides purely pyroclastic sediments, lahar deposits have also been identified around the remnants of the volcanoes.

Beneath a lahar deposit at Korsaröd, Early Jurassic plant fossils including wood, pollen and spores have been exceptionally well preserved. The degree of preservation is such that cell-scale features like organelles and chromosomes have been identified in the fossils. At this location plants grew in a substrate with extensive hydrothermal alteration.

The volcanism is possibly the result of decompression melting of the lithospheric mantle beneath. The volcanism is linked to a rift flank fault along the Sorgenfrei–Tornquist Zone, which is a failed rift associated with extension in the North Sea and the opening of the North Atlantic. The background to the volcanism is the break-up of Pangea, and thus it is analogous to the much more voluminous Karoo-Ferrar flood basalts of Southern Africa.

I Skåne finns rester av ett hundratal vulkaner, som uppstod under juraperioden. Det var under denna tid som Pangea-kontinenten började brytas upp, och en gammal plattgräns, Tornqvistlinjen, som går snett över Skåne, utsattes för belastning. Vulkanerna uppstod där Tornqvistlinjen sprack, de flesta utbrotten var av strombolisk typ.
