Petrographic and geochemical investigations of ground stone tools made of basalt from the site Csanádpalota – Földvár, SE-Hungary

• During the Late Bronze Age huge mega-forts emerged in the Great Pannonian Plain. • The occupants used both local and long-distance sources for their macrolithic tools. • The macrolithic finds are diverse in terms of function and raw material as well. • Source rock identification needs multiple methods (petrography and geochemistry) • Trachybasalt raw material originates from the Lucareţ – Şanoviţa volcano (Romania) The middle Late Bronze Age Pre-Gáva/Cruceni-Belegis II Phase (cca. 1350–1100 BCE) fortified settlement of Csanádpalota – Földvár is located on the Hungarian-Romanian border in South-East-Hungary. The ground stone tool assemblage of the megasite has a large variety of raw materials, e.g. different types of sandstones, volcanites, metamorphic rocks etc. In this work, we are focusing on the detailed petrographic and geochemical investigation of the basalt raw material, and the comparison with the various types of Neogene-Quaternary alkaline basaltic rocks in the Carpathian-Pannonian Region. Based on the similar mineral composition and texture, bulk rock chemical composition and the composition of the olivine and spinel minerals the most probable source of this raw material is the Lucareţ – Şanoviţa (Lukácskő-Sziklás) volcano (Banat Region, Romania).
