The research was focused on the testing of possible information value of charcoal analysis from infills of archaeological objects, when methodologically different approaches are used in the combination with the micromorphological and pollen-analytical approach. The case study site chosen for this type of study is the unique Early Medieval settlement at Roztoky, Czech Republic. The comparative study includes the infills of 20 pithouses from the extensive settlement comprising about 750 (323 excavated) such archaeological structures situated along the left bank of Vltava River close to what today is the city of Prague. A combination of three anthracological outcomes (the number of charcoal fragments, the anthracomass, and the qualitative frequency of charcoal species) proves to be a powerful tool in determining the vegetation pattern in the surrounding landscape. The study revealed a major effect of post-depositional processes and quantification methods on the final anthracological interpretation. A modification of the anthracological record in different layers was traced in order to assess the applicability of sedimentology and micromorphology in the interpreting of the primary use and ending of the objects found. The reliability of anthracological interpretations are then compared with the results of micromorphological analyses and with regional vegetation patterns interpreted from pollen analyses of an off-site pollen profile.
