摘要：The excavation of the tumulus discovered at Regöly – northern part of Tolna County – started in spring 2011.
According to the archaeological observations it was built in the Iron Age.
Based on the structure of the mound and the archaeological examination of the pottery sherds, connection can
be assumed in the east and west directions. All this is attributed to the westward migration from Central-Asia.
About 6000 potsherds were found in the mound. According to macroscopic observations (colour, grain size,
mineralogical composition) 14 main types were defined. In this article, the second most common type, the fine
black ceramics were examined. The goals of the examination were to characterize the composition of the sherds
(plastic and non-plastic components) and compare them with the already examined coarse ceramics and the
local argilliferous sediments, in order to outline their origin as local or non local. Polarizing microscopy and
scanning electron microscopy (SEM-EDX) analysis were used to achieve these goals.
According to the non plastic components of the potsherds two subgroups can be separated. The significant
difference between the two subgroups is in the composition of the heavy minerals. One of its most characteristic
feature is that it contains a significant amount of Cr-spinel. The biggest Cr-spinel is 250 µm, the average size of
the Cr-spinel crystals is 40-60 µm. On average, their composition are 54 wt% Cr2O3, 17 wt% Al2O3, 19 wt%
FeO, 9 wt% MgO and low amount of CaO and TiO2 (~ 0,1 wt%).
16 sites of mafic-ultramafic (and serpentinite) rock occurrences are known in the surrounding of Regöly, and the
path of the migration. 12 of these (2 European, 10 Asian) are known to contain Cr-spinel. Based on these, the
Cr-spinel bearing ceramic from Regöly refer to non-local raw material outside the Carpathian Basin.
