After having spent 8 years at the University of Bergen (Norway) where I had used array of the ICP-MS and laser instruments for isotopic analysis of geological materials (Single collector, double focusing magnetic sector ICP-mass spectrometer Thermo Finnigan Element 2, NU Attom; Multi-collector, double focusing magnetic sector ICP-mass spectrometer Thermo Finnigan Neptune, NU Plasma II; New Wave UP-213 NdYAG laser system, Resonetics excimer 193 nm laser ), I returned back to the Academy of Sciences in Prague in 2016. Here I pursue a number of different topics of geology with focus on geochemical applications. Besides the routine LA-ICP-MS U-Pb zircon dating, in-situ zircon Hf analysis and Lu-Hf chemical dilution techniques I will focus on a developement and implementation of new (chemical abrasion for LA-ICP-MS zircon dating) as well as classical methods (ID-TIMS U-Pb dating of accessory minerals).

My research will now be more focused on the Variscan orogenic system while keeping connections to the topics I used to work on previously (Scandinavian Caledopnides, S. Africa - S.America panafrican orogen, zircon detrital provenance studies etc.)

Ongoing and future projects:

• Study of the zircon provenance of the metamorphosed Variscan rocks in Central Europe (Bohemian Massif)

• Petrology, geochemistry and evolution of the Kaoko Belt in Namibia and its relationship to the South American counterpart

• Geology of Scandinavian Caledonides
