Nd-Sr-Pb isotopic signatures of Neoproterozoic?Early Paleozoic siliciclastic rocks in response to changing geotectonic regimes: A case study from the Barrandian area (Bohemian Massif, Czech Republic)

Abstract

Nd-Sr-Pb isotope data are used to chracterize the sources of Late Neoproterozoicand Early Paleozoic siliciclastic rocks of the Teplá-Barrandian unit of the Bohemian Massif. Geochemical and isotopic signatures of samples from different stratigraphic levels reflect changing sources and weathering conditions through time and allow a correlation with shifting geotectonic regimes.
