Recent geodynamic processes in a central part of Europe, its geological and tectonic developments and knowledge of geophysical fields help us to understand better mutual interactions between old and young European geological units. Old units in this area are represented by the East European Precambrian Platform and the Central and West European Paleozoic Platforms and young units by the Alps and the Carpathians belonging to the Alpine-Himalayan Orogen. Studies of motion origins and interactions between the old resistant and the young mobile units contribute reasonably to understanding of Central European geodynamics.
The Department of Geodesy and Photogrammetry, Agricultural University of Wroclaw, in collaboration with the Institute of Rock Structure and Mechanics, Academy of Sciences of the Czech Republic, organized the 4th Czech-Polish Workshop on Recent Geodynamics of the Sudety Mts. and Adjacent Areas in Lubawka (Poland) on November 7-9, 2002. The workshop was held under the auspices the Section of the Geodynamics of the Committee of Geodesy, Polish Academy of Sciences, the Section of Satellite Geodesy and Geodynamics, Academy of Engineering in Poland and the Czech Center for Earth Dynamic Research. Forty-eight participants from nineteen Czech and Polish research institutions and universities attended the Workshop. The scientific programme of the Workshop was focused on topics concerning the recent mobility of the Sudety Mts. and adjacent geological units. The field session to the "Dobromierz" geodynamic network and "Ksiaz" seismologic observatory was included into the programme.
Delivered contributions allowed a broad community of geologists, geophysicists and geodesists to be mutually informed. Even if many of them had an interdisciplinary character, their topics were directed mostly to the following items:
a) regional and local geodynamic networks,
b) GPS data monitoring and processing, and
c) analyses of geological and geophysical data relating to geodynamic activities.
The 4th Workshop on Recent Geodynamics of the Sudety Mts. and Adjacent Areas gave a good opportunity to present new results of all geodetic and geodynamic projects realized under national and/or international cooperations. A total of thirty-two papers were presented. This special issue of the journal Acta Montana, Series A contains seventeen papers.
The organizers wish to express their satisfaction that the 4th Workshop as well met with a great response among geo-scientists being interested in this area. Their warm thanks go to all participants of the Workshop and to all authors, who submitted their contributions for a presentation in this way. Particular thanks are due to the Institute of Rock Structure and Mechanics, Academy of Sciences of the Czech Republic for printing this special issue of the journal Acta Montana, Series A. The supports granted by the Grant Agency of the Czech Republic, research project No. 205/01/0480 and by the Ministry of Education, Youth and Sport of the Czech Republic, project LN00A005 "Center for Earth Dynamic Research" are highly appreciated and acknowledged.
