Research

Topics:
- The post-collisional high-K calc-alkaline / shoshonitic granitoids and their transition to post-collisional and anorogenic alkaline to peralkaline granitoids.
- Relations between magma emplacement, shear zones, terrane movements and lithospheric thickness. Geodynamic reconstruction of Precambrian orogenies in Africa.
- Setup and development of the concept of metacraton.

Fieldwork areas:
The Pan-African orogeny (end of Neoproterozoic) in Saharan regions (Tuareg shield in Mali, Niger and Algeria; Anti-Atlas in Morocco, Egypt, Sudan). The Pan-African basement within Alpine nappes in the South Carpathians (Romania). The Birimian (c. 2100 Ma) juvenile terrains of West Africa (Mali, Niger).
Since 2003, the main targets are the Tuareg shield and the Anti-Atlas.

Main methods:
- U-Pb, Sm-Nd, Rb-Sr geochronology; Sr, Pb and Nd isotope geochemistry; major and trace element geochemistry.
