It was compiled primarily to reconstruct the location of the archaeologically invisible forge hearth within a late 6th and early 5th century BC smithy in Building 24 at Pungrt Hillfort, central Slovenia. The analysed sediment samples were systematically collected in a 50×50 cm grid during the excavation of the building. Archaeobotanical remains were extracted using flotation and examined and sorted under a stereomicroscope. In addition, charcoal fragments were examined under a light microscope and a selection of cereal food fragments were analysed using scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS). Sediment analyses measured magnetic susceptibility, pH, organic matter content, plant-available phosphorus, nitrogen, potassium, and carbonates. The results were spatially analysed using Geographic Information System (GIS) and Surfer software. 20242025-02-03 15:57:53Neznano167014sl
