| Description | Micromorphology in the archaeological context is a methodological tool of modern multidisciplinary archeology. It is basically a microscopic characterization of sediments in a direct context of archaeological situations with the aim of detecting formation processes, the knowledge of which is essential for further interpretations. This method was applied to the sediment fill of two features in a stratigraphic relationship from the locality Tvrdonice – “Pole od Týnecka”. Samples were taken from a La Tene recessed structure fill and an earlier Bronze Age pit that is superimposed below the La Tene feature.From a macroscopic and micromorphological point of view, it is evident that the fill of an Early Bronze Age feature consists of wind-blown sands in superposition with in situ or slightly displaced soil material. Micro-layers detected macroscopically are only related to object leveling. The layer of soil beneath the “floor” of the La Tene recessed building displays signs of long-term bioturbated soil, i.e. the La Tene building was founded in an existing depression. The active floor layer of the La Tene building is represented by alternating layers of lighter and darker laminae. While the darker laminae represent the trampled layer, the lighter laminae consist of recrystallized ash, which impregnates the trampled layer. On a social level, this finding can be interpreted as the creators of the La Tene recessed building choosing to minimize labour costs by using the recessed terrain and thus avoiding the excavation of the building floor. The utility area possessed a purposefully modified surface, which is related to ergonomic efficiency, but its function is unknown. The uppermost part of the fill is formed by backfill that does not show any signs of pedogenic influences, which indicates that the object was intentionally filled (leveled). |
