First Circular of a meeting titled „Way and type of occurrences and activities of deep-seated faults of the eastern part of Austria and Western Hungary” Date: 21 October 2011 Place: Sopron, Csatkai E. u. 8. (Hungary), POB 05 Venue: Geodetic and Geophysical Research Institute Antecedents Based on joint proposal an agreement has been approved by the Austrian and Hungarian Academies of Sciences titled “Correlation of tectonic lines and units in the upper crust revealed by geological methods and deep crustal/lithospheric structures imaged by geophysical methods in the East Alpine – Pannonian domain” aiming to identify correspondences and solve contradictions found between surface occurrences and downward disappearences of deep-seated faults of the study area. Scientific aspects and objectives The Pannonian Basin and the surrounding Eastern Alsp, Carpathians, and Dinarides have been a fascinating scientific target for many generations of geoscientists. Geological research has a long tradition in this area and gained a wealth of information on composition, structure and tectonic development. An intensive phase of geophysical exploration of the crust and deeper lithosphere began about 10 years ago. Geophysical – especially seismic – models were generated and new results emerge continuously. All this data show that a transformation of the geophysical image into the geological view, and vice versa, is not an easy task. Scientific cooperation and exchange of ideas and arguments between geologists and geophysicists have substantially improved during the last decades. However, further increasing collaboration is necessary to bring together geological and geophysical views and to achieve a deep understanding of geodynamic processes in this area. The main objective of the proposed cooperation is the development of tectonic/geodynamic models of the Eastern Alps and the Pannonian domain by integrating existing geological and geophysical data and models. The achievement of this goal implies that participating geologists and geophysicists get a sound understating of meaning, accuracy, resolution, and uniqueness of all geoscientific data integrated into the models. At the kick-off meeting held in the “Montan Universität” Leoben have been decided that geophysicists and geologists interested in the subject get together annually in Hungary and in Austria. The first scientific meeting will be organized in Sopron. Preliminary program of the day Morning session: 10:00-13:00 Lunch-break: 13:00-14:00 Afternoon session: 14:00-17:00 Subjects of the meeting - Structure of the Mohorovicic discontinuity and Upper Mantle of the broader area (Eastern Alps, Western Carpathians, Pannonian Basin) General geological and geophysical introduction of the Mid-Hungarian, the Periadriatic-Balaton, the Rába, and the Mur-Mürz Lines Geophysical methods used for delineating tectonic structures (seismic and non seismic ones) Although this meeting is planned as a two-sided project geophysicists and geologists from Poland and Czech Republic, Slovakia, Slovenia, Croatia are also welcome.
