| Description | Geoarchaeological prospection techniques were applied to identify activity zones and the inner structure of a homestead at the Early Mediaeval site Pohansko near Břeclav (Czechia). By a combination of geophysical methods, the spatial distribution of microartefacts, geochemical analysis and multivariate statistical analysis, we outlined various manifestations of anthropogenic activity. We examined obtained data by Spearman's correlation coefficient, spatial autocorrelation (Global Moran's I) and robust Principal component analysis to identify the spatial pattern of the area. Recognized joint presence of heavy metals (Pb, Zn and Cu) and elements related mostly to organic matter, waste and ashes (S, P and Ca) as well as a small number of slag fragments probably indicate presence of metalworking zones or mixed zones with domestic and industrial debris at the homestead. Further anthropogenic activities could be connected to manuring, animal management or some kind of production activities based on the presence of Mn, P and Cu. Bone and charcoal concentrations supplement the information of geochemical analysis and may indicate the manner of waste management in the peripheral parts of the homestead. In the middle of the homestead, the location of archaeological features indicates an open space in which no specific activity was detected. By means of magnetic susceptibility and judging from the presence of daub, we defined the potential presence of non-sunken features, which were not recognized by magnetometry. The outcome of the study is yet to be verified by excavation. |
