Typology and cultural-chronological variability of bifacially worked implements 347 Typology and cultural-chronological variability of bifacially worked implements of siliceous rocks from the territory of Russian Karelia Alexey TARASOV Bifacially worked implements made of siliceous rocks constitute one of the most sig- niicant groups of lithic tools from archaeological sites in present-day Karelia from the Neolithic to the Early Metal Period. In the present paper a generalised description of these artefacts during the whole period of their existence is given and the typology of these implements is discussed. The spread of bifacial industry, which was followed by the disappearance of blade industries, can be considered an epochal phenomenon, one of composing parts of the “Neolithic package” along with pottery production. The main tendencies in the development of bifacial industry were common for a very large territory of the forested zone of eastern Europe. Artiklis antakse ülevaade silikaatsetest kivimitest labatehnikas valmistatud esemetest, mis on üks peamisi leiurühmi neoliitikumist kuni varase metalliajani tänapäeva Karjala alal. Kirjeldatakse esemete iseloomulikke jooni ning arutletakse nende tunnuste alusel loodud tüpoloogia üle. Labatehnika levik, mille järel laasttehnika hääbus, oli epohhi loov fenomen, mis koos keraamika valmistamise oskusega oli üks olulisimaid osi „ne- oliitilisest komplektist”. Labatehnikas töödeldud esemete arengujooned on sarnased laiadel aladel Ida-Euroopa metsavöötmes.
