The Steinkogel is 742 m above sea level. A. high hill in the western part of the Grazer Bergland in the Austrian state of Styria . It is located in the northwest of the provincial capital Graz and is its second highest elevation.
Location and surroundings
Together with the Generalkogel, the Steinkogel forms a small massif between Plankenwarth and Gösting , which is described in the literature as the Steinkogel-Frauenkogel train. Other well-known elevations are the Frauenkogel at Straßengel and the Göstinger ruins mountain . The ridge is bounded in the north by the Gratkorner basin , in the east by Murtal , in the south by the Thaler basin and in the west by Luttengraben and Rötzgraben. The actual summit is - like the entire ridge - densely forested and inconspicuous, but it forms the second highest elevation in the Graz city area after the prince status. It is part of the protected landscape area of the western mountain and hill country of Graz (LSG-39).
Geology and geomorphology
The Steinkogelzug consists of mitteldevonischen limestones and dolomites of Rannach - facies essentially from east to west or northeast to southwest strike and shallow to medium in part from the north to the northwest come . The Plabutsch, separated by the deeply incised Thaler Bach, belongs to the same lithology .
On the ridge there is between 680 and 700 m above sea level. A. a widespread level that presents itself in the area of the Steinkogel as a strongly karst flat area . There are two forms of karst phenomena; on the one hand, flat cone-shaped peaks , including the Steinkogel, Generalkogel and Straßengelberg, and on the other hand, some large sinkholes . The peaks occur both in the limestone and in the dolomite and rise above the top level by 30 to 40 m. They are covered with rubble and have been flattened by periglacial processes. Herbert Paschinger suspects it is a heavily shaped conical karst , which corresponds to the warm, humid, subtropical climate of the Upper Miocene . He sees the origin of the level differently than his thought leader Arthur Winkler-Hermaden before pannon . The cones, as they can also be observed on the Tanneben or the Hochlantsch , are formed, according to Paschinger, with frequent inundation from wide karst areas at deep levels.
The sinkholes intervene in the slopes of the hilltops with steep slopes, from which it can be concluded that the hollow forms were created later. They also lack the pannone gravel surface. Some of them go back to the clearing of the Graz basin in the middle Pliocene . Smaller, steep sinkholes probably of Holocene origin are sunk into the rather flat sinkholes with a diameter of 100 to 300 m . There are also some ponors on the south side of the Steinkogel .
