Detrital zircon populations in quartzites of the Krkonose-Jizera Massif: implications for pre-collisional history of the Saxothuringian Domain in the Bohemian Massif

Popis výsledku v původním jazyce

Age spectra of detrital zircons from metamorphosed quartzites of the Krkonose-Jizera Massif in the northeastern part of the Saxothuringian Domain were obtained by U-Pb laser ablation inductively coupled plasma mass spectrometry dating. The zircon ages cluster in the intervals of 450-530 Ma and 550-670 Ma, and show individual data between 1.6 and 3.1 Ga. Zircons in the analysed samples are predominantly of Cambrian-Ordovician and Neoproterozoic age, and the marked peak at c. 525-500 Ma suggests a late Cambrian maximum age for the sedimentary protolith. Detritus of the quartzites probably originated from the erosion of Cambrian-Ordovician granitoids and their Neoproterozoic (meta) sedimentary or magmatic country rocks. The lack of Neoproterozoic (meta) sedimentary rocks in the central and eastern part of the Krkonose-Jizera Massif suggests that the country rocks to voluminous Cambrian-Ordovician magmatic bodies were largely eroded during the formation of early Palaeozoic rift basins alon
