Lithospheric density model along the CEL09 profile and its geological implications

Original language description

We present a new 2D lithospheric density model along the seismic profile CEL09 crossing the Bohemian Massif, the Western Carpathians, and the Pannonian Basin. The resulting model consists of five principal layers: sediments, upper crust, lower crust, lower lithosphere, and asthenosphere. The thicknesses of the Neogene sedimentary basins vary from 0 to similar to 5.5 km while the Paleogene flysch sediments dip to a depth of similar to 6.5 km. The most complex upper part of the upper crust in the Bohemian Massif is represented mainly by low-density granitoid plutons (similar to 2.60-2.68 g cm(-3)), metamorphic rocks (similar to 2.69-2.74 g cm(-3)) and high-density basic and ultrabasic bodies (similar to 2.78-2.79 g cm(-3)). In the Western Carpathians, this layer is formed by the crystalline Male Karpaty Mts. (2.66-2.67 g cm(-3)), Trans-Danubian range (2.73-2.74 g cm(-3)), and the pre-Cainozoic basement of the sedimentary basins (2.67-2.74 g cm(-3)). The densities of the lower part of the upper crust range from 2.78 g cm(-3) (in the Western Carpathian-Pannonian region) to 2.77-2.80 g cm(-3) (in the Bohemian Massif). In the lower crust, four different sectors were modelled. In the Saxothuringian, they are divided into two layers, the upper layer (2.84-2.85 g cm(-3)) and the lower layer (3.12 g cm(-3)). The Moldanubian has the thickest lower crust (similar to 20 km) with a density of 2.98 g cm(-3). The lower crust in the Moravo-Silesian has a density of 2.97 g cm(-3). The Western Carpathian- Pannonian region is represented by slightly lower densities of 2.94-2.96 g cm(-3). The gravity modelling indicates that the Western Carpathians were overthrusted by similar to 30 km onto the Bohemian Massif resulting in a neo-transformation of the crust/mantle and related lithosphere after subduction.
