With the analysis of the middle Bronze Age (2000–1350 BC) Vatya culture findings in Pest county (Central Hungary) comprising of more than 400 polished stone tools and instrument tools this is the first archaeometric study with such scale in Hungary. In order to characterize petrographically the raw- material of the stone tools macroscopic and microscopic stone analyses were made together with mineralogical and geochemical analyses. In the course of the work a new digital database the Archaeometric Stone Tool Database was established. Based on the results, the material of the instrument stones is mainly sandstone and quartzite that were easy to collect from their source areas. Local volcanics, mostly amphibole containing andesite variations dominated among the material of the polished stone tools. Ophiolites (metamorphic basic rocks, serpentinized basic and ultrabasic rocks) were the raw-material of stone axes that indicate either more distant travels for raw-material or exchange import.

The middle Bronze Age (2000-1350 BC) Petroarchaeology is a specific part of Vatya culture occupying the central part of the archaeometrics involving the mineralogical, Danube-Tisza Interfluve (Fig. 1) has special petrological, geochemical and other geological, significance from several aspects as it controlled the physical and chemical analysis of mineral or stone most important routes in the Carpathian Basin: the material tools for archaeological purposes (Herz & Danube and the associated smaller river network in Garrison, 1998; Rapp & Hill, 1998). central Hungary. Natural conditions of this area In case the geological view is applied in determined fundamentally the lifestyle of the culture studying archaeological tools, questions can be in which agriculture had a central role. This is one of answered that could be researched less effectively by the most completely explored Bronze Age tell other methods. Results can contribute to the better culture in Hungary with variable settlement types, understanding of the lifestyle, movements and multi-layered society, marked and united findings technical development of stone cultures (Pető & (Bóna, 1992). Kelemen, 2000; Szakmány, 2009). The analysis of more than 400 stone tools of Based on this approach, we have been studying the Vatya culture from Pest county presented here is the stone tool findings of the middle Bronze Age the closing stage of our research. Analysing the Vatya culture since 1996 in the framework of an known polished stone tools and instrument stones of archaeologist – geologist co-operation. The results the whole culture presents the opportunity for such were of significant interest from both archaeological overall statistical analyses that would not be possible and geological points of view (Farkas–Pető, 2008; on the basis of only a few localities, tools or Horváth et al., 1999; 2000a; 2000b; 2001; Pető et al., instrument types. 81 Figure 1.

Archaeometric stone tool database The first rock based stone register in Hungary, the Lithoteca was established in the Hungarian National Museum and it has become available electronically (T. Bíró & T. Dobosi, 1991; T. Bíró, 2005, T. Bíró et al., 2000). On the basis of this idea we created the Archaeometric Stone Tool Database during the years of studying the stone tools of the Vatya culture. The primary base of this new register is the detailed archaeological-petrographic- geochemical characterization of the stone tools with the identification of the probable source area. 3. RESULTS 3.1.
