28 amphibolite Neolithic polished stone implements deriving from different archaeological localities and cultures in Northeast Hungary (Borsod-Abaúj-Zemplén County) were archaeometrically analysed by mainly non-destructive methods (MS, EDS/SEM, PGAA). Bulk chemistry of the samples showing subalkali characteristics. The amphibolite polished stone tools were divided into two groups based on their mineral components and metamorphic evolution. A single Ca-amphibole approach was used to calculate peak P-T conditions to determine a thermobarometric model for the amphibolite implements. Data of the studied samples were compared to those of the nearest amphibolite outcrops in Gemericum, Veporicum, Tatricum and Zemplinikum (Slovakia). The Variscan P-T loop covered the thermobarometric data of the analysed stone implements and the amphibolite outcrops. The source areas are assumed to be these fields and/or the crossing riverbeds flowing through them to Borsod-Abaúj-Zemplén County, the archaeological collecting territory of the amphibolite stone axes.

The Baradla Cave has been an open and used natural cavity since ancient times. 20 pieces of polished stone tools of various raw materials were revealed from the cave site, which were analysed using non-destructive methods. Source areas were identified for those raw material types which have detailed mineralogical and rock chemistry data available. The main raw material types are blueschist and contact metabasite, defined as a close and a distant raw material, respectively. The latter was widely known for its excellent mechanical properties. In addition, subordinate greenschist-amphibolite, serpentinite, sandstone, limestone, basalt litho-typed polished implements were also identified from the Cave, but their source area can be determined only tentatively from the available analyses and previous publication data.
