The Mur-Mürz furrow is the name given to the long valley cut by the two rivers Mur and Mürz , which extends from Tamsweg to Semmering . It is the southeastern core area of the otherwise mountainous region of Upper Styria and the Lungau in the State of Salzburg and includes the landscape areas of Upper Murtal and Mürz Valley as well as some inner-alpine basins of the Noric Depression in this valley .
geography
The valley, which is about 200 kilometers long in west-south-west-east-north-east direction, begins in the Muhr / St. Michael im Lungau area ( 1017 m ), runs along the Upper Mur Valley via Tamsweg , Murau , the Aichfeld (Judenburg-Knittelfelder basin) and the Leoben basin , then at Bruck an der Mur ( 491 m ) up the Lower and Middle Mürz Valley , into the Fröschnitztal , over the Semmering Pass ( 985 m ), and down the Schwarza to Gloggnitz and Neunkirchen ( 371 m ), where it is in the valley of Wiener Neustadt dives under the Vienna Basin .
To the north it is largely accompanied along its entire length by the Murparallel valley , the basins of these two valley ranges together form the Noric Depression.
To the north of the Mur-Mürz-Furche are the Niedere Tauern (or the Murberge as their subgroup), the Eisenerzer Alps , Hochschwab and Mürzsteger Alps (or the Mürz Valley Alps ). In the south, the Gurktaler , Seetaler and Fischbacher Alps , as well as the Stub and Gleinalpe form a barrier to the Graz Basin .
geology
The lineament , which is very clearly visible on satellite images and takes up a third of the length of the Eastern Alps , is a striking geological fault line and in some places the epicenter of earthquakes . The Mur-Mürz Valley Fault consists of a large number of mutually moving faults that range from the Murtal to the Semmering. There the fault zone divides, one branch continues eastwards on the southern edge of the Vienna Basin , another branch runs on its western edge. Geodynamically , the southern part of the Mürz Valley is shifted towards the northeast, which leads to an expansion of the Vienna Basin.
