GRAFITOVÁ KERAMIKA ZO SÍDLISK DOBY LATÉNSKEJ Z NITRY. MINERALOGICKO-PETROGRAFICKÉ ŠTÚDIUM

As there are no graphite deposits in the nearest surrounding of Nitra, it is apparent that the graphite was imported from other regions as a raw material or in form of graphite doped vessels. The graphite ceramics is present in all studied localities but the content of this ceramic is very variable from locality to locality. Sherds from various localities in Nitra (Šindolka, Chrenová II and III, Martinský vrch, Mikov dvor) were chosen for the mineralogical and petrographic characterization. Four main types of graphite doped ceramics were distinguished according to the mineralogical and petrographic composition of non-plastic inclusions. Comparing the experimental data with already published data and/or with geological settings of graphite deposits it was partly possible to determine the provenance of the graphite raw material. The graphite raw material from petrographic type (I) comes from Moldanubikum (southern Bohemia and Lower Austria), type II and type III comes from the Moravia – Silesia region. Especially the type II comes from the velkovrbenská dome (nearest surrounding of Jeseníky Mts.
