Geodynamics of Central Europe. Current status of geotectonic investigations in Central Europe

Reports on Geodesy

The report contains the description of monitoring of recent crustal movements in the European region covered by the CEGRN stations with highlighting the geologic, geophysical and geodetic aspects of studies carried out by European scientific institutions. The report includes the information coming from different sources and in particular from studies performed by the CERGOP-2/Environment work package subgroups WP10.1 - WP10.7. These sub-groups currently arranged, planned and organised programmes of their activities in particular regions in a fully independent, self-determining and "sovereign" way. So the report was currently updated by the results of investigations of the sub-groups WP10.1-WP10.7. Since all chairmen of work packages were obliged to report their activities at the EGU-CEI symposia in April every year it was expected that the three main inputs of new results of investigations would be available in April 2004, April 2005 and April 2006. The chairmen of work packages had also to concisely report the activities of their sub-groups at the CERGOP-2 Working Conferences that were organised every year in fall time. So, also a short updating of the Pilot Report was possible after the CERGOP-2 fall conferences.

A short introduction to the geology, structural evolution, geophysical fields and geokinematics of the area studied by the CERGOP-2 countries and work package subgroups

Looking at the geological map (Fig.l) and the geotectonic division of Europe (inset scheme on Fig.l) we can see, that the area investigated by the 7 groups for regional investigation (WP 10.1 to WP 10.7) of the CERGOP - 2 work package WP 10 "Geodynamics of Central Europe" (see tab. 1 for subjects and chairs) belongs almost exclusively to the Alpine Europe, called also Neo-Europe, a sector of the Alpine-Himalayan erogenic belt. More exactly this includes mountain chains from the Eastern Alps through Carpathians to Balkanides on the northern and north-eastern side of the major Alpine suture zone known in the Eastern Alps as Gailtal Line through substrate of Neogene Pannonian Basin to the Vardar Zone and the Southern Alps through Dinarides to the Hellenides on the southern and south-western side of these suture zone (Ager 1980, Peive et al. 1982 and Fig. 2). The forefield of the Eastern Alps-Carpathians-Balkans Alpine fold-and-thrust belt is very heterogenous and comprise tectonic units of Variscan (=Hercynian, e.g. Bohemian Massif of Czech Republic including the neighbouring strips of Austria, Germany and Poland), Caledonian (?, suggested within the Transeuropean Suture Zone - TESZ - of northern Germany and Poland, by Stille 1950, Znosko 1986 and questioned by Glazek 1995, Malinowski et al. 2005, Guterch & Grad 2006; cf. Fig. 3), and Ancient East European Craton - EEC (Ukrainian-Moldavian sector of the East-European Platform). To the SE the TESZ is covered by Alpine structures of the East Carpathians and again emerges in Dobrogea close to Black Sea (Fig. 2). There TESZ divide the EEC from the late Precambrian Moesian Platform (in Romania and Bulgaria) squeezed in between Balkanides (=Stara Planina) and southern Carpathians (Peive et. al. 1981,1982). These structures were described in details in a series of monographs published in Reports on Geodesy by the Chief Editor J.Sledzinski as results of the CERGOP-1 Study Group CSG 8 "Geotectonic analysis of the region of Central Europe".
