Petrography and geochemistry of ceramics, plaster and local silty clay from an early Neolithic site of Körös culture (Szarvas and Endrőd, SE Hungary)

Szakmány György – Starnini, Elisabetta

Abstract

The lecture summarizes the results of comparative petrographic and geochemical investigation of pottery, other non vessel clay artefacts (plaster, net weight) and as potential raw materials, local clayey sediments from early Neolithic (Körös culture) site of Szarvas and Endrőd.

Pottery have sandwich structure, serial-weakly hiatal fabric (fine grained) and their non-plastic inclusions are similar to the mineral fragments of plasters, net weights and the local Pleistocene-Holocene clay-silt and soil. Plant tempering (mainly chaff and different types of grass) can be identified in ceramics and plasters. This feature could be recognized on the basis of characteristic pore shape and phytolite determination. Raw material of pottery was a carbonate-free sediment while there are calcareous and carbonate-free types among the raw materials of plasters. Chemical compostion of ceramics shows a narrow range whereas plasters have varied geochemical signal. Pleistocene and Holocene sediments are similar to each other but there are some differences in their chemical composition and distribute in a wider range than pottery and plaster.

To sum up, ceramics and plasters were made of non-prepared local raw material. In addition pottery was fashioned of a more clayey (with higher Al-content) fine-grained sediment than other artefacts.
