Utilization of archive geophysical data for geodynamical studies in the Sudetes: Example of Bela fault zone (the Nizky Jesenik Mts.).

Abstract

Geophysical data are used not only, in geological mapping, exploration of mineral resources, hydrogeology, but are also important for other branches such as environmental protection, civil engineering and archeology. That is why, within the project CzechGeo/EPOS (www.czechgeo.cz), geophysical data access is solved as a separate topic under the guidance of the Czech Geological Survey (hereinafter CGS). In accordance with the current needs of national and international activities (INSPIRE, EPOS, IAGA), an inventory of available data, its consolidation and harmonization according to national and international standards is conducted. The aim is to store securely and permanently valuable data, which in many cases cannot be reinstated.

On the example from the Nizky Jesenik Mts. possible advantages and utilization of Archive data for mapping and verification of the movement tendencies gained from GNSS networks - EPN, EAST SUDETEN and MORAVA are demonstrated.

Very valuable information for the interpretation of structural and tectonic conditions is provided by geophysical data (seismic reflection profiles, gravity and magnetic data, etc.) in the area of interest, especially in terms of monitoring the main fault systems and the character of the basement structures.
