Short description of project
The crystalline basement rocks from the Pannonian Basin and Internal Dinarides are some of the least known rocks of disrupted European Variscan and Alpine belts. Published papers offer several in some cases even contradictory views on the evolution of these crystalline complexes. Thus, the questions about the details of the metamorphic - deformational history and precise timing of mineral growth related to particular tectonothermal events are still open. In part, these questions raise from the shortcomings of published age data which are either whole-rock data or mineral ages but poorly supported by precise descriptions of mineral assemblages and their relations. In order to constrain age data and link them to the specific mineral assemblage we will focus mainly on the analyses of particular mineral assemblages. Available analytical methods (X-ray powder diffraction method - including illite and chlorite "crystallinity" and b0 barometry, vitrinite reflectance, X-ray fluorescence spectrometry, microprobe measurements, geothermobarometry, K-Ar and Ar-Ar dating and microprobe dating technique on monazite) will be used primarily to determine petrology, P-T conditions, geochemistry, tectonic setting and geochronology of analyzed rocks. In the frame of our previous projects, beside obtained K-Ar ages in the Dinarides, several unexpected ages were obtained by microprobe age dating technique (Permian, Silurian, Ordovician and Precambrian - preliminary measurements) together with so far unregistered K-Ar Cretaceous ages in the Slavonia. New age data needs further elaboration and confirmation. In respect to our objectives one could expect refinement of obtained ages and the definition of events on the regional scale, accompanied with registration of less intensive thermal substages. Multidisciplinary approach will allow control of obtained results. The data will be correlated with existing ones for adjacent Variscan and Alpine complexes with the aim to obtain adequate geodynamic interpretation for crystalline complexes of adjoining area between Alps, southern Pannonian Basin and Dinarides. This is important form the regional, as well as the global geological aspect because of geotectonic position of these metamorphic complexes and definition of their role in the evolution of Europe.
