Studium geografického rozptylu surovin broušené a štípané industrie v neolitu umožnilo určit hlavní trendy distribuce těchto odlišných typů surovin. Zatímco zastoupení silicitových surovin klesá na 30 % ve vzdálenosti 70–150 km od zdroje, v případě metabazitů z Jizerských hor je situace značně odlišná. Ve starším neolitu mají téměř stoprocentní zastoupení i na jižní Moravě, ve vzdálenosti 250 km od zdroje (Vedrovice). Distribuční areál suroviny je obrovský a zcela nesrovnatelný se soudobými distribučními systémy surovin pro štípanou industrii. Distribuční systém spolu s těžbou fungoval ve stejném rozsahu až do konce staršího stupně kultury s vypíchanou keramikou. V této době se dílny přemísťují do nížiny a zpracovávají méně kvalitní surovinu z teras řek. Zároveň se objevují další ve východních i středních Čechách. Vedle toho se ve velké míře začíná experimentovat s jinými surovinami, které ale již nikdy nedosáhnou takové kvality. Starý distribuční systém se zhroutil a byl nahrazen novým, který byl více regionalizovaný a v mnohém odpovídá situaci v distribuci silicitové suroviny. and A study of the geographical dispersal of the raw materials for Neolithic polished and chipped stone industries enables a determination of the main trends in the distribution of these different types of raw material. While silicite raw materials vary at around 30 % representation at distances of 70–150 km from their sources, in the case of the metabasites from the Jizerské hory [Mountains] the situation is markedly different. In the early Neolithic these latter have almost 100 % representation even in South Moravia, at a distance of 250 km from their source (Vedrovice). The distribution area of this raw material is enormous, and is entirely incomparable to the contemporaneous distribution system for raw materials used to make chipped stone industry. The distribution system, together with extraction, functioned at the same scale until the end of early phase of the Stroke-Ornamented Ware culture. At this time, the workshops moved into the lowlands and worked with less high-quality material from river terraces. At the same time, others appear in eastern and central Bohemia. In addition, there was a greater degree of experimentation with other raw materials which, however, never attained such a quality. The old distribution system collapsed and was replaced by a new one, which was more regionalised and which in many ways is reflected by the situation in the distribution of silicite raw materials.
Metabasic rocks of the Želešice type were one of the most intensively utilized raw materials used for the manufacture of Neolithic polished industry in the Middle Danube region. Primary sources are located in the Ophiolite Belt (formerly Metabasite Zone) of the Brno Batholith, approximately 5 km SW of Brno. All sites represent secondary workshops that are not located at the outcrops. Quarrying at the outcrops has not been directly confirmed for this period. The focus of this work is a complex description of a unique primary workshop recently discovered nearby primary outcrops. Recently obtained data has revealed new information about the lithic operational stages, morphology, dimensions and procurement of the raw material. Petrographic analysis reveals several subvarieties of metabasic rocks which were utilized to different degrees. Another goal of this work is to add to the debate regarding terminology of workshop sites., Jaroslav Bartík, Lukáš Krmíček, Tereza Rychtaříková, Petr Škrdla., and Obsahuje seznam literatury
