An improved structural map of the pre-Neogene basement for the area of Rechnitz-Hannersdorf (Burgenland/Austria)
by Franz Weber & Herfried Graßl
Abstract: An improved structural map of the pre-Neogene basement constructed from refraction seismic data of the area Rechnitz–Hannersdorf (Burgenland/Austria) is presented. Apparently, WSW–S Rechnitz and N–NE Hannersdorf the basement dips below the Cenozoic sediments without faults. An easterly striking trough, 3 km south of Rechnitz, is connected with the syncline of Großpetersdorf in the west and a regional long striking trough in the northeast, in western Hungary. This structure disrupts the “Southburgenland Swell” and can be of some geologic-tectonic importance. West of Schandorf, the pre-Neogene basement shows a pronounced relief with a jump in the basement velocity at the centre of a small trough indicating a change in the basement lithology. In the area under investigation the basement predominately is composed of Penninic rocks, besides Palaeozoic carbonates exist.
Key Words: Penninic window of Rechnitz; Pre-Neogene basement; Southburgenland Swell; Styrian Basin.
