Our purposeful petroarchaeological investigation of the Neolithic and Eneolithic in Czech Silesia has been in progress since the beginning of new millennium. The most important results are represented: described distribution of silicites from the Kraków-Częstochowa Jurassic and hypothetical identification of organized system for a long-distance distribution of this raw material towards the west in the 6th millennium B.C.; expert opinion on the dynamics of raw material basis for polished industry in form of 4 groups that are different from the chronological and typological points of view and also by their position in the archaeological classification system; formulation of a hypothesis about connection of an Early Eneolithic group of polished tools with a hypothetical allochthonous population that took share in the genesis of Funnel Beaker culture and later living of this population on peripheries; identification of a manufacturing – consuming system connected with the Upper-Silesian facie of the Funnel Beaker culture and based on the Culmian raw materials (especially siltstones and silty slates of Lower Carboniferous age) of the Nízký Jeseník Upland; interpretation of the settlement Racibórz 150 as an episodic interference of foreign (most likely from Lower Silesia) population with the Funnel Beaker culture; in times of Corded Ware culture suggestions for more close relationships of Upper (maybe also Lower) Silesia to Moravia – these regions form a relative unity comparing Little Poland or large lowlands in northern Poland. Our new findings also offer possibility of alternative views on same problems connected with archaeological and generally historical recognition of economic and social relations in Central Europe during 6th -3rd millennium BC.
