f S-Waves Study of the Origin of the Bright Spots in the Transdanubian Central Range

The Transdanubian Central Range is situated west of the Danube and cast of lake Balaton. At the first approach its structure is asymmetrical synclinorium with imbricate block structure. By the axis with NW-SE direction Jurassic and Cretaceous formations and on the flanks older Mesozoic and Paleozoic formations care be found. The investigations in the last decade proved the close connection between the North Pannonian Alpian unit (which is part of the Transdanubian Central Range) and the Drauzug unit. The region is considered to be the area of allochton development and it must have moved to the present position by horizontal movements during the Middle Alpine tectogenetic events (Horváth et al., 1993)
