Burgenland

Eisenberg

Most of the vineyards are located on unconsolidated, mostly silty but also sandy or gravel, young lake and river deposits of the Styrian Basin, that extend toward the east into the Pannonian Basin. They are not only extremely variable in grain size, but also in the carbonate content of the limestone and dolomite components.

In the northern and central parts of the wine region, on the southern slopes of the Güns Mountains and in the areas of Hannersdorf, Königsberg, Eisenberg and Csater Berg the vines are rooted upon diverse consolidated rocks of Mesozoic and Palaeozoic age. These include calcareous phyllite, greenschist and serpentinite of the geological unit of the Alps referred to as the Penninic Superunit. Similar rocks, such as those found at Rechnitz and Eisenberg, also form Austria's highest peak, Mount Großglockner. Freshwater opals are another remarkable feature that can be found in the vineyards at Csater Berg.
The vines at Hannersberg and at Königsberg are rooted in soils derived from consolidated rocks such as dolomite, limestone and shale, which are older than the Penninic Superunit, and belong to the Austroalpine Superunit of the Alps.

Leithaberg

The oldest rocks are the acidic schist and gneiss of the Austroalpine Superunit that form the central part of the Leitha Mountains and support the highest lying vineyards between Breitenbrunn and Donnerskirchen as well as individual vineyards at Eisenstadt and Oslip. However, the most striking rock of the area is the Leitha Limestone. It developed in the quiet shallow water of a warm sea that surrounded the Leitha mountain range approximately 16 - 11 million years ago where small reefs were able to grow. The Leitha Limestone is a consolidated, light-coloured algal limestone and is rich in remains of sea creatures such as mussels, gastropods and sharks. In contrast, slightly older, quartz-rich, sandy gravels occur on the Rust Ridge. Separated by a tectonic displacement from the Leitha Limestone, two very different parent rocks of the vineyard soils are found here directly next to each other: on one hand, acidic and on the other hand calcareous.

In the topographically lower levels the vineyards are located on unconsolidated, mostly calcareous silts, sands and gravels of the Pannonian Basin and on loam, lacustrine clay and alluvial gravel deposits. The deposits of the area of Pöttelsdorf form part of the Vienna Basin and are mostly fine-grained and locally covered by loam.

Mittelburgenland

On the southern slopes of the Ödenburg Mountains, the vines are sited on the consolidated rocks of the Austroalpine Superunit, on acidic schists, paragneiss and coarse gneiss. Towards the basin follows a nappe formed of coarse, crystalline gravels, which in turn is overlain by unconsolidated, partially weakly consolidated quartz-rich sands. These sediments already belong to the marine development of the inner alpine basins at the eastern margin of the Alps, which began about 16 million years ago. At the same time Leitha Limestone developed in the areas of Neckenmarket and Ritzing. Within the basin, the sediments became ever more fine-grained towards the south-east, to silty-clayey grades and up to almost pure clay deposits that are known only from the Central Burgenland wine region. These fine sediments show a highly variable carbonate content, they can also be carbonate-free, and bear local enrichments of iron in the form of clay ironstone and limonite nodules. Gravel layers occur within these sediments, but also occur as a cover in the form of strips of Pleistocene terrace remnants.

In the easternmost part of the wine growing area layers of loess and loam dust are predominant, which in turn partly overlay either terrace gravels or fine-grained sediments of Lake Pannon.
