Sevel Limestone Quarry is located a few 100 m north of the road between Holstebro and Viborg at Bjergby. This is a large abandoned limestone quarry that contains the ruins of several limekilns (pot-shaped kilns) and a sizeable ring-shaped kiln. The site includes the limestone quarry itself and the former plant area with the kilns (Figure 45-1).
This site contributes to our understanding of the evolution and dynamics of salt structures where it has been demonstrated that activity has continued right up to late glacial times. The Vejrum salt structure (site 44), on the other hand, provides information on processes at a deeper level. It has also been demonstrated that the topographic expression of the Sevel salt dome has influenced the movement of the ice (as was the case at Odby Klint: site 42). This leads to a more general topic; to what extent has there been interplay between the underground salt structures in the region and the movement of glaciers through the ice ages? A concrete example is the detailed relationship between the salt structures and the shape of the sea that formed in the Holsteinian interglacial period. This in turn led in the long run to the shape of the western part of Limfjord (site 6 Toftum Bjerge).
The limestone quarry and plant area are accessible to the public. The limestone quarry has been conserved together with a tributary valley to lake Stubbegård Sø. It is therefore part of a large protected and maintained nature area. There is a path that connects with a system of paths in the conserved area around lakes Stubbergård Sø and Flyndersø, as well as the heathland area at Hjerl Hede where there is a Countryside Museum (Frilandsmuseet) (Figure 45-1).
The topographic features that led to this conclusion were the presence of several tectonically-controlled valleys and the dry, late glacial tributary valleys to the Karup outwash plain. These indicate that the salt structure has “tipped” in late glacial times (down to the west and up to the east), after formation of the Karup outwash plain (Figure 45-3).
