Leopoldsdorfer Bruch

The Leopoldsdorf fracture system is a series of geological fractures on the western edge of the Vienna Basin .

The rift system runs roughly north-south and begins at Leopoldsdorf just south of Vienna until it runs out below the Mitterndorfer Basin after about 40 kilometers . The northern continuation is the Bisambergbruch , which forms the western edge of the basin at the Wiener Pforte and runs through under the Danube at the foot of the mountain of the same name .

Tectonically, the Leopoldsdorfer Bruch is a steeply sloping interface between the basin sediments and the solid subsurface of the Vienna basin. At its steepest point it has a jump height of 4,000 to 5,000 meters and separates the Hochscholle von Oberlaa (where thermal waters also rise) from the Schwechater Tief , a 6,000-meter-deep depression under the city of Schwechat .

The Vienna Basin is criss-crossed by a few hundred fractures, which represent an old weak zone in the earth's crust between the Eastern Alps and the Carpathian Mountains . The Leopoldsdorfer break is after Steinberg fraction has the farther north even 6000 feet of vertical drop, the second most powerful of these underground faults .
