OBJECTIVES / ACTIVITIES
1. Analysis/critical review of current models for geodynamic evolution of the Eastern Carpathians, as part of the CPR and its inter-connection with magmatic activity.
2. Building up a computer data-base of geological and geophysical data for the studied area.
3. Identification and deciphering the space-time relationships of the main volcanic structure and intrusive bodies, their interval of emplacement using K/Ar dating, petrological, geological and geophysical data; establishing the geological significance of the combined geophysical anomalies and identification of hidden intrusive bodies;
4. Identification and characterization of the main tectonic alignments associated to, or in close association with magmatic activity by using geological and geophysical data; identifying the orientation of extensional and compressional stress fields;
5. Building-up 3D images for selected volcanic structures and hidden intrusive bodies based on the geologic interpretation of geomagnetic and gravity models, in order to assess their volume, emplacement and evolution;
6. Proposing a complex novel regional model for the emplacement of various volcanic structures and intrusive bodies in close connection with geodynamic processes and comparing with similar geological situations in the world.
