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

本数据集支撑扇三角洲成因砂质砾石沉积的地层学（stratigraphic）、沉积学（sedimentological）及宇宙成因核素年代学（cosmogenic nuclide geochronological）研究。该套沉积形成于约11.6~9.4 Ma（百万年前），沉积位置为多瑙河盆地东缘，而该盆地是中欧潘诺尼亚盆地体系（Pannonian Basin System）最北端的沉积中心。本次研究的核心目标为验证该地层的地层位置、沉积过程及沉积持续时长。本数据集包含自生10Be/9Be测年的实验室样品处理流程细节，可保障分析工作的可重复性。此外，本数据集收录了用于地质剖面（geological sections）对比的归档钻孔清单，包含获取数字档案中原始手稿所需的全部相关信息。本数据集基于激光雷达（Light Detection and Ranging, Lidar）数据生成的数字高程模型（Digital Elevation Model, DEM）对所分析的露头进行了特征描述。本数据集为Nemčiňany遗址提供了相分布综合柱状图，配套沉积学方案及标注测年采样点的照片图板。相关研究论文为Šujan等（2023）发表于《Geologica Carpathica》的文章，链接为https://doi.org/10.31577/GeolCarp.2023.25，文中包含了沉积学及古地理解释内容。
