The Hausruck is a chain of hills in the foothills of the Alps in Austria , which forms the eastern part of the Hausruck and Kobernaußerwald range. It has a length of about 30 km. The highest point is the 801 meter high Göblberg . The Kobernaußerwald lies in the southwest of the low mountain range . The Hausruck, still Haussrugg in the 19th century , gives the Hausruckviertel , one of the four quarters of Upper Austria , its name.

Location and landscape

The Hausruck is a shallow hill country , partly of a low mountain range densely wooded with spruce forests , consistently commercial forest , occasionally also with near-natural oak-hornbeam forests , in the streams and hilly edge zones rising cultivated land. In the center of the mountain range, the proportion of forest is around 90%, in the settlement area around 35%. The Hausruckwald , together with the Kobernaußerwald, is one of the largest contiguous forest areas in Europe. In the settlement area, the landscape elements are small-scale, the settlement low. The grasslands are nutrient-rich meadows, but also widespread mossy forest meadows and other types of rough meadows . Near-natural vegetation groups are rare there.

The main ridge is flat, with heights of 700 to 800 meters, the valleys are feathered . The most important rivers are northwards Waldzeller Ache , Oberach (Antiesen) and Antiesen to Inn, eastwards Trattnach and Weinbach over the Innbach to the Danube, southeast and southwards Ottnanger Redlbach , Ampflwanger Bach , Frankenburger Redlbach and Fornacher Redlbach to Vöckla and Ager / Traun / Danube, and southwest Schwemmbach via Mattig to the Inn. There are no lakes, ponds and ponds are very rare.

Boundary and neighboring regions

According to the mountain group classification according to Trimmel , the Hausruck is listed as No. 1577 (under 1570  Flysch area and Alpine foothills between Salzach and Traun and the large group 1500 Eastern Salzkammergut Alps added to the south  ). The orographically designed structure delimits the Hausruck as follows (clockwise):

The western border to the Kobernaußerwald, which is hardly visible in the landscape because the ridge continues evenly, is also seen differently in the literature. There are about:

  • the Ager / Traun watershed (Danube below Jochenstein ) to Salzach / Inn (Danube above J.) via Florianikapelle (691 m), Kalteis (734 m) and Hamberg , which then turns to the east Eberschwang swings away (Antiesen to the Inn)
  • the Fornacher Redlbach , with continuation to the Waldzeller Ache , so that the Meisterholz (711 m) above Pöndorf still belongs to the Kobernaußerwald
  • and even - almost across the aforementioned lines - from Frankenburg along the ridge over the Hamberg westwards to Steiglberg (767 m, Kobernaußerwaldwarte ) and then northwards, with which the Hobelsberg ( Ries'n , 777 m) falls between Fornach and Frankenburg into the Kobernaußerwald , and is then also named as its highest elevation.

In any case, the communities of Lohnsburg (by name) and Waldzell on the north slope consistently belong to Kobernaußerwald, Schildorn to both and first Pramet to Hausruck, in the south Pöndorf to Kobernaußerwald, Fornach and Redleiten to both, and Frankenburg (by name) to Hausruck, so in this regard roughly the Line Vöcklamarkt - Redleiten - Schildorn (just west of Frankenburger Straße L 509, from Ried iI right southwards) could be used.

The Upper Austrian spatial planning structure (NaLa - nature and landscape) does not distinguish the Hausruck independently in the Hausruck and Kobernaußerwald  (HKW) spatial unit ; it also sets the area within much narrower boundaries, which roughly correspond to the 600-meter contour line in large areas.

The following regions are adjacent (clockwise):

climate

The climate is rich in precipitation and has up to 1200 mm of precipitation per year, the annual mean temperature is between 7.6 and 7.8 ° C. The Hausruck-Kobernaußerwald-Zug lies in the central area of ​​the funnel-shaped area of ​​the Central European transitional climate . About 65% of the annual precipitation falls in the summer half year, the precipitation maximum coincides with the temperature maximum in July. A typical secondary maximum in February repeatedly leads to snow breaks . The amount of precipitation increases to the east, the temperature decreases, so that the climate is harshest on the eastern slope.

The mean wind speed is relatively high and is 2-3 m / s, wind throws occur regularly in spring and autumn storms, but the Hausruck is also the location of Austria's first wind power plants .

Geology and mineral resources

The Hausruck is composed primarily of streaks and gravel . There are deposits of lignite there , but mining has stopped. There are also smaller oil and natural gas deposits , among others. a. near Puchkirchen . Small gravel pits are scattered around the area, and brickworks can also be found.

The Hausruck - like the Kobernaußerwald - is formed from neogene sediments , solidified tertiary foreland molasses . The reason why this mountain range is characteristically free is unclear; tectonics and post-sedimentary bulges can be ruled out. In any case, at the time of the formation of the Kobernaußerwald in Badenium , the Hausruck was mainland, the Schliersockel was eroded in a wavy manner. The profile of the younger strata below the main ridge gravel is also erosively shaped. It is still unclear whether the Hausruck - or the entire foreland coal - was forest or was registered as Schwenngut from the Alps.

The stratigraphic-lithogenetic structure of the Hausruck is as follows:

  • Innviertel series - clay-marly and sandy formations of the Ottnangium (around 18  mya , radiometrically dated locally to 22-23 mya), deposited in a shallow marine environment ( Paratethys )
    • Vöcklaschichten - Schliere in the southeast along the Vöckla
    • Atzbacher Sande - Vöcklabruck to Lambach, 60 to 80 m thick; fine to medium-grained quartz-rich sands, mica-bearing, light gray to greenish gray, often brownish weathered in the outcrop
    • Ottnanger Schlier - in the south and east of the Hausruckkamm; gray, green-gray or gray-blue clay marl, thinly layered with mica-rich layers of fine sand
    • Rieder layers - north of the Hausruck; gray-blue to greenish-gray, mica-bearing, weakly fine sand clay marl, thinly layered with layers and lentils of fine sand
  • Leading carbon freshwater layers (predominantly), pelitic gravels and sands of - Badenian to Unterpannon , discordant layered (Slavonium, 11-7 mya), limnic-fluvial sediments to moderate; Lumpy soft brown coal / matt coal, almost sulfur-free, from sequoia and angiosperms , also pine cones, but outside of the coal fossil-free (also without microfossils)
  • Hausruckschotter - up to 170 m thick top layer of the main ridge, upper Unter-Pannon, rising and thickening towards the east (on the Kölblberg about 140 m, upper edge of the coal series at 660–680 m); Gravel ( quartz , various gneisses , black silica slate , red, gray and white limestone , marl and sandstone ), maximum grain size gravel to medium gravel, coarse sand layers, often inclined and cross stratification, conglomerate and sandstone banks , fossils (wood, dorcatherium , Hipparion , Dicerorhinus , Mastodon )
  • are covered these layers of quaternary sediments, gravel cover in the north, moraines and alluvial of the trenches in the south, where there is also loess find

Geologically, the Hausruck differs from the Kobernaußerwald primarily in that the sands emerge in the south, in the Kobernaußerwald on the north slope, and there the coal-bearing freshwater layers are more extensive, but connected to the much more extensive gravel cover layer, and are therefore well represented on the southern roof. The streak layers are used for agriculture, the gravel is forested. The upper freshwater molasse continues to the Upper Austrian-Bavarian border, which also includes the Siedelberg, east of the Mattig Valley, and the coal areas around Trimmelkam .

Groundwater reservoirs are the coal-bearing freshwater layers that open up the area with high levels of precipitation in numerous typical local house and local wells , the Gießerquelle (supply Wolfsegg, Ottnang and Zell aP) pours up to 9 seconds liters . Nevertheless, most of the municipalities' central wells and increasingly also house wells are deep wells in the Schlier.
