Abstract: Integration of Remote Sensing-, 3D-Seismic and Microtectonic Data for Fault Pattern Analyses in the Vienna Basin

Tectonic interpretations in the Vienna Basin like in other hydrocarbon bearing sedimentary basins are hindered by limited outcrop conditions. For the correct evaluation of the structural geometry and evolution of the basin a detailed R&D study is carded out, which integrates multisensoral satellite imagery, 3D-seismic data, and microtectonic methods to delineate timing and kinematics of faulting. Remote Sensing use images showing different imaging geometries and spatial resolutions to rule out effects which lead to a suppression of lineaments parallel to the sensor look direction. Data of scanners mapping the visible and infrared spectrum and SAR-data operating in the microwave range are interpreted. The high sensitivity of microwaves to surface roughness and soil moisture and their capability to penetrate the surface makes them a useful tool for mapping morphology and lineaments. A DEM is used for geocoding and generation of perspective views. Directional filter kernels are applied to enhance edges in the multitemporal data set. Image interpretation revealed that the Vienna Basin is characterized by lineaments trending N-S, NE-SW and NW-SE. The directions correlate to fault patterns mapped in time slices. N-S to NE-SW striking normal and sinistral faults bound rhomb-shaped divergent fault duplexes which were active between 17-8 Ma. Younger NW-striking normal faults resulting from NNE-SSW directed extension have a pronounced morphologic expression by paralleling the drainage pattern. Microtectonic analyses of surface outcrops allow the establishment of a deformational and paleostress history which can be used to predict timing and direction of movements along subsurface faults as well as their sealing capacity.
