South-eastern Poland is situated between the East European Craton (EEC), the Paleozoic and Mezosoic of Western Europe and the Carpathians. Complex geological structure of the area is reflected on the maps of potential fields anomalies. The analyses of the total magnetic intensity anomaly map ∆T and the vertical derivatives of these anomalies in relation to geological data provide many information concerning the structure and magnetic properties of rocks of the crystalline basement. These analyses indirectly reveal the degree of the petrologic diversification and the tectonics of the basement in comparison with the adjoining blocks of the Paleozoic and Variscan orogens and their basement as well as those located in the area of the Trans–European Suture Zone (TESZ). Two dimensional (2D) magnetic models of the basement along the seismic profiles (CEL 01, CEL 05) and corresponding three dimensional (3D) model have been constructed. This interpretation is based on spectral analysis of the magnetic anomalies and their quantitative interpretation which includes data from the CELEBRATION 2000 project, as well as information concerning the magnetic properties of rocks made available through drilling. The comparative analysis of maps showing magnetic and gravity anomalies have revealed the architecture of the crystalline basement in the area where the East European Craton (EEC) is in contact with the Paleozoic and Mezosoic of Western Europe, as well as its impact on the image of residual gravity anomalies within the area of the craton. |
