Tamsweger basin

View from the east of Tamsweg, Salzburg. In the background, the neogene Tamsweg basin moves from the center of the picture to the right, while the Mur today comes from the left behind the striking St. Leonhard Church and curves towards the point of view of the picture.

The Tamsweg Basin is an inner-alpine basin in the northeast of Lungau . It is part of the Noric Basin , which arose in the Neogene (formerly the Young Tertiary) , long before the Mur took its modern, southern course from St. Michael via St. Margarethen and Unterstberg to Tamsweg and Ramingstein .

The Neogene deposits begin at the base with breccias and conglomerates of angular rock debris or rubble from the neighboring and underlying Upper Eastern Alpine basement blankets ( mica schist , paragneiss ) east of the Tauern window . As a result, shale and sandstones were deposited, which in some places contain lignite to an economically insignificant extent.

The deposits occur in a narrow west-east trending strip between Mariapfarr , St. Andrä and the Tamsweg districts of Wölting, Haiden and Sauerfeld, but are repeatedly covered by glacial moraines .

In the late 19th century, attempts were made at St. Andrae and Wölting unsuccessful, the low powerful lignite seams reduce.

Definition of terms

The landscape term Lungau Basin , unlike the geological term above, refers to the terrain that is predominant in eastern Central Hungary with the comparatively low and gentle mountain ridges between the Niedere Tauern in the north, the Hohe Tauern in the west, the Nockberge in the south and the Murbergen in the Lie east.
