Spatial and temporal changes of sandstone provenance in the Krkonoše Piedmont Basin and their tectonosedimentary implications

Spatial and temporal changes of sandstone provenance in the Krkonoše Piedmont Basin and their tectonosedimentary implications
The Krkonoše Piedmont Basin formed as part of system of extensional/transtensional basins during the late phases of the Variscan orogeny and early post-orogenic period. Shifting of depocentres at the Stephanian B/C and Autunian/Saxonian boundary show to a distinctive changes of basin configuration. Driving mechanisms of these changes are poorly understood so far. This project intends to decipher these mechanisms based on the provenance investigations using heavy mineral analysis, U/Pb age of detrital zircon and fission track analysis of detrital apatite and zircon on several stratigrafhic levels and lateral areas of the basin. Obtained data will be compared to the potential source areas. This work will result in establishing a model of tectonosedimentary development of the basin including reconstruction of sediment dispersal pathways and a model of erosional history and tectonostratigraphical development of surrouding crystalline units.
