Provenances of Fine-Grained Alumosiliciclastic Material for the Vendian and Early Cambrian Sedimentary Rocks of the West of the East European Plate: Some Lithogeochemical Constraints

The lithogeochemical peculiarities (content and distribution of main rock-forming oxides, as well as some trace elements) of clayey rocks of the Volynian, Redkinian, Kotlinian, and Lower Cambrian stratigraphic levels of the west of the East European Plate (Belarus and Volyn, east of the Baltic Monocline, and Moscow Syneclise) are analyzed. Using various lithogeochemical approaches and methods and data on U–Pb isotopic age of detrital zircon populations, which occur in sandstones associated with mudstones, and taking into account geochemical peculiarities of possible source rocks of fine-grained alumosiliciclastic material (igneous associations of different composition and age of Sarmatia and Fennoscandia), we provided ideas on a possible contribution of the latter associations to the formation of the Vendian and Early Cambrian clayey rocks.
