Stratigraphic, sedimentological, geochemical, mineralogical and geochronological data characterizing the Upper Miocene sequence of the Turiec Basin, Western Carpathians (Central Europe)

The data included in this article specify the characteristics of the Upper Miocene fill of the Turiec Basin and served for reconstruction of temporal evolution of depositional systems in this intermontane basin located within the Western Carpathians (Central Europe). The borehole lithological log data were used to describe the stratigraphy of the Turiec Basin in geological sections and were gained in the Geofond archive of the State Geological Institute of DionATIN SMALL LETTER Y WITH ACUTEz Stur. The sedimentological data were acquired by field research applying facies analysis to nine outcrop sites. The outcrops served for grain size analyzes performed by sieving and laser diffraction, for geochemical analyzes using ICP-ES, ICP-MS , XRF , for mineralogical analyzes of whole rock and clay fraction by XRD. Moreover, the muddy layers on out-crops served for collection of 31 samples for the authigenic 10Be/9Be dating. The geochronological data are presented by using five different initial ratios for calculation, determined within the Turiec Basin at the Late Pleistocene alluvial fan and river terrace sites as well as at two Holocene muddy floodplain sites. Another initial ratio data are gained from an Upper Miocene lacustrine succession dated independently by magnetostratigraphy in previous research. Finally, a summary of previously published strontium isotope data from the Turiec Basin is included. The interpretations of the data are provided in Sujan et al., specialIntscript Palaeogeography, Palaeoclimatology, Palaeoecology 628, 111746. (c) 2023 The Author(s). Published by Elsevier Inc.

Automated summary

This article presents the characteristics of the Upper Miocene fill of the Turiec Basin and reconstructs the temporal evolution of depositional systems in this intermontane basin. Borehole lithological log data and sedimentological data from field research were used to describe the stratigraphy of the basin and analyze the grain size, geochemistry, mineralogy, and geochronology of the sediments. The results provide valuable insights into the geological development and environmental changes in the study area.
