标题：Adatok az Árpád-kori sánc építését megelőző kora középkor kérdéséhez Sopronban = Data on the chronology of Early Mediaeval layers before the construction of the Árpád Age fortification in Sopron
摘要：Although, the first archaeological excavations at Városház str., Sopron were already made in the 1960s, the detailed processing of findings and the publication of results are still unfinished. Based on short archaeological reports, however, it has been claimed that there is a 10th c. settlement layer just below the well known, Árpád Period woodenstructure rampart. Nevertheless, in the light of more recent works there is a chance that ceramic findings excavated from the layer and suggested to represent the 9-10th/9-11th/10-11th c. AD were originally misinterpreted. In order to resolve the problem above, thermoluminescence dating (TL) was applied for 3 representative pottery fragments originating from the questionable layer. Samples were performing well during TL measurements, their sensitivity and TL signals were high. Nevertheless, as a matter of uncertainties in the radioactive background the relative error of age calculations was as much as 13-15 %. Two of the specimens, forming one group by typological means as well, were dated to be of similar age, and were fired in the 310 BC –250 AD time interval. The third pottery fragment was significantly older and was dated to the Late Bronze Age. The validity of these results was reinforced by the measurement of a fourth, archaeologically well established Late Bronze Age sherd. Considering the age results, the investigated specimens certainly do not represent the youngest group of ceramic fragments of the investigated layer, thus they seem to be improper for telling the minimum age of the Sopron dark earth layer, from where no other unambiguously Middle Age fragments were excavated either. As a consequence, considering both typological and absolute dating results we claim that the present pottery family cannot be used for proving the existence of a Conquest Period settlement layer beneath the Sopron fortification. Moreover, the early or mid 11th c. origin of the fortification cannot be supported either by the dark earth layer and its pottery findings alone..
