| 1. Dataset overview |
| RIP-ARCHAEOGEOCHEM (ver. 1.0.0) |
| An archaeogeochemical landscape dataset from the Mount Říp region, Czech Republic |
| This dataset was created by the Geoarchaeological Lab of the Centre for Field Archaeology, University of Hradec Kralove, as part of the project Long-term Land Use Dynamics within the Areas of Prehistoric Ritual Places (GACR Grant No. 25-15795K), funded by the Czech Science Foundation. It contains topsoil geochemical data collected in the Mount Říp region, Czech Republic, to support the investigation of archaeogeochemical signatures and long-term patterns of anthropogenic soil enrichment across the landscape. The dataset contains 1,291 topsoil samples, including elemental concentrations obtained by portable X-ray fluorescence spectroscopy (pXRF), together with metadata describing field sampling, laboratory processing, and the spatial location of each sample. |

| 3. Sampling methodology |
| Field sampling was carried out in March and April 2025 within a 10 × 10 km study area south-east of Roudnice nad Labem, Czech Republic, in the wider Mount Říp region. The sampling design combined two complementary strategies. First, a regular landscape-scale grid with 1 × 1 km spacing was used to capture broader regional geochemical patterns. Second, this grid-based sampling was supplemented by targeted sampling of archaeological sites divided into predefined categories, including settlement-related contexts, burial-related contexts, ambiguous feature concentrations, and background/non-site areas. At each selected archaeological location, a 50 × 50 m sampling square was established, within which 30 topsoil samples were collected randomly. Sampling locations were predefined and uploaded to the ArcGIS Field Maps mobile application, which was used to navigate to each sampling point. Sample locations were verified in the field using a smartphone with a minimum positional accuracy of 10 m, and all samples were collected from the surface ploughsoil (topsoil) horizon. |
| 4. Laboratory workflow |
| Laboratory processing of the collected samples was carried out between May 2025 and February 2026. Samples were air-dried under laboratory conditions, manually pre-crushed and sieved to obtain the <2 mm fraction. Approximately 40–50 g of each sample was then homogenized using the laboratory's internal PM_9 protocol. Samples were milled for 3 minutes in a planetary ball mill using a mixture of 4 mm and 7 mm grinding balls with a total ball volume of 36 mL. Elemental concentrations were determined using an Olympus Vanta VCA portable energy-dispersive X-ray fluorescence (ED-XRF) spectrometer (serial no. 801404) operating in GeoChem-REE-Extra mode. Each sample was analysed using dual-beam irradiation (50 kV for 30 s and 10 kV for 30 s) and measured in triplicate. The reported elemental concentrations represent the arithmetic mean of the three measurements. Concentrations below the instrument's limit of detection were replaced by one-half of the minimum detected concentration for the respective element. Elemental concentrations are expressed in parts per million (ppm). |
