Geodynamics of Late Palaeozoic rift basins on the east European platform : Pripyat-Dnieper-Donets basin, Belarus, Ukraine and Russia

Objectif



The rift basins of the east European platform (EEP), and the Pripyat-Dnieper-Donets (PDD) basin in particular, are among the key targets identified by the multidisciplinary, multinational EUROPROBE programme. This project was developed within this framework. Rifting played an important role in the Late Palaeozoic and subsequent evolution of the European lithosphere. The EEP, Devonian-Early Carboniferous rifted sedimentary basins and their genetically-related post-rift thermal sag basins host important hydrocarbon resources. Rift-related magmatic activity was also associated with the development of other mineral deposits and diamond-bearing structures. In west and central Europe, Devonian and Early Carboniferous rifting was intrinsically related to the post-orogenic evolution of Palaeozoic Europe. The primary objective of this multidisciplinary project is to gain a better understanding of the geodynamic processes which governed the Late Paleozoic rifting activity of Europe. Within a framework of regional scale studies of the sedimentary basins of the EEP, the main target is the PDD basin.

The following tasks will be carried out: development of a regional Late Palaeozoic geodynamic synthesis for the EEP, involving construction of revised plate reconstructions and correlation of tectonic and magmatic events; analysis of available data and collection of new high quality geochemical and isotopic data for primitive, rift-related, magmatic rocks, constraining mantle source-depths and paleotemperatures; analysis of the processes which control the evolution of the Late Palaeozoic sedimentary infill of the PDD and other basins from structural, sedimentary facies and biostratigraphic studies; development of dynamic models of the regional tectonic evolution of the PDD basin consistent with geophysical characteristics of the crust and mantle along transects of varying degrees of basin inversion; integration of the basin fill and tectonic models, in order to study the interactions of tectonic and non-tectonic (sea level and climatic) processes influencing the development of sedimentary sequences; use of the quantitative modelling framework to make thermal metamorphism and hydrocarbon maturation predictions.

The results of these studies will be compiled in a number of scientific publications. Also available in the publications, but documented separately, will be regional tectonic maps.
