Repeated earthquake swarms and exhalation of mantle-derived CO2-enriched fluids are important expressions of presently ongoing magmatic processes in the intra-continental lithospheric mantle of the Western Eger rift region. The geodynamic nature and the implications of these processes are far from being understood. Neither the origin of magmatic activity (upper mantle or lower crust?) nor the geodynamic role of fluids are well constrained. We would like to address these issues by modern reprocessing of two deep reflection seismic profiles from neighbouring areas (German DEKORP MVE-90 and Czech 9HR profiles). We will establish correlations between deep microseismic and reflecting structures. The seismic imaging approaches will be universal for both profiles. The microseismic data and reflection structures will be obtained using common velocity models. This will improve possible correlations and enable a comparison of the Eger Rift features to reflection and microseismic features of the neighbouring KTB site, where a similar methodology has been already applied. The expected results (and a small magnetotelluric feasibility study included in this proposal) will help to design a new high resolution seismic reflection profile crossing a persistent swarm area of the Cheb Basin. Such a profile, in turn, will be a pre-site study for scientific drilling.
