Sedimentological and geochronological data for the fan deltaic Nemčiňany Formation, Upper Miocene, Danube Basin (Slovakia)

This dataset supports the stratigraphic, sedimentological and cosmogenic nuclide geochronological study of the sandy-gravelly deposits of fan deltaic origin, which were deposited during ca. 11.6-9.4 Ma in the eastern margin of the Danube Basin, which is the northernmost depocenter of the Pannonian Basin System (Central Europe). The study was focused on verification of the stratigraphic position of this formation, of the depositional processes and duration of the deposition. The dataset includes a detailed description of laboratory sample processing for the authigenic 10Be/9Be dating, which allows the reproducibility of the analyzes. Furthermore, the dataset contains a list of archival boreholes used for correlation in geological sections, including the information necessary to access the original manuscripts in a digital archive. The analyzed outcrops are characterized in this dataset by digital elevation model maps using Lidar data. A generalized log of facies distribution is provided for the Nemčiňany site, together with a sedimentological scheme and a photopanel showing sampling points for dating. The sedimentological and paleogeographic interpretations are included in the related paper Šujan et al. (2023) Geologica Carpathica, https://doi.org/10.31577/GeolCarp.2023.25
