Upper crustal model of the Ohře Rift and its vicinity

The region of the Ohře Rift in the northwestern part of the Bohemian Massif attracts attention of scientists due to the exceptional geological phenomena: contacts of geological units, significant faults, large granitic massifs, sedimentary basins with lignite deposits, Tertiary and Quaternary volcanism, mineral springs and seismic swarms. The project will yield a three-dimensional anisotropic model of seismic velocities to a depth of about 15 km with a specification of the boundaries of the geological bodies. The derivation of the model will be based on seismic tomography. The following seismic data will be used: refraction data from international profiles, measurements of local earthquakes and industrial shots. Geological maps, data from boreholes, physical parameters of rocks and gravity data will be used as well. The model will facilitate the solution of the problems of tectonic evolution of the rift, depth range of geological bodies, origin of mineral springs and earthquakes.
