The Vienna Basin (Template:Lang-de, Template:Lang-cz, Template:Lang-sk) is a sedimentary basin between the Eastern Alps and the Carpathian Mountains.

Geography

The fairly level area has the shape of a spindle, over an area of Template:Convert by Template:Convert. In the north it stretches up to the Marchfeld plateau beyond the Danube River. In the southeast, the Leitha Mountains separate it from the Little Hungarian Plain. In the west, it borders on the Gutenstein Alps and Vienna Woods mountain ranges of the Northern Limestone Alps. The Danube enters the basin at the Vienna Gate water gap bear Mt. Leopoldsberg, it leaves at Devín Gate in the Little Carpathians east of Hainburg.

From the late 12th century onwards, the fortresses of Wiener Neustadt and Hainburg were erected at the southeastern and eastern rim as a defensive wall against attacks from the Hungarian lands downstream the Danube River. Nevertheless the forces of King Matthias Corvinus entered the Vienna Basin during the Austrian-Hungarian War in 1485 to begin the Siege of Vienna. It was again invaded by Ottoman troops, who besieged the city in 1529 and 1683.

Structuring

thumb More than 80% of the basin area belong to the Austrian states of Lower Austria and Vienna, the northern parts on the Morava (March) and Thaya Rivers are part of the Czech Republic and Slovakia. Along the southern and western rim geothermal and mineral water springs occur in several spa towns like Baden, Bad Vöslau and Bad Fischau-Brunn.

Parts:

  • Vienna Basin proper. The part within the Czech Republic is called Dolnomoravský úval (Lower Moravian Vale), whilst that within Slovakia is called Borská nížina (Bor Lowland, part of the Záhorie region)
  • Marchfeld (Moravské pole) in Lower Austria
  • Chvojnice Hills (Chvojnická pahorkatina) in Slovakia.

The Bor Lowland and Chvojnice Hills are known collectively as Záhorská nížina (Záhorie Lowland).

Geology

The Vienna Basin formations are a series of sedimentary layers that were deposited in the Neogene. It was formed by pull apart mechanism and the Vienna Basin fault system on which the Vienna Basin lies remains seismically active. Significant earthquakes that propagated across the Vienna Basin include the Neulengbach earthquake of 1590, and the strong temblor that hit Carnuntum in the mid-4th century.
