Раннеголоценовая стоянка Джварцхма в Западной Грузии
Early Holocene Jvartskhma site in Western Georgia

Summary/Abstract: The Jvartskhma site indicates the Boreal age of the culture layer. The stone industry of the site describes process of the beginning of the use of hand pressing flaking for obtaining the pressing blades. The prismatic and conic cores were used in order to get blades and bladelets. The complex of flint and obsidian tools consist burins on truncated facetted blades, dihedral burins on flakes, end scrapers, retouched blades, blades with notches, truncated facetted blades. There are trapezes, which were made on pressing blades. There are some sites in Western Georgia connected with the technology of production of trapezes on pressing blades. In our opinion, the big center of the new technology appeared in Western Georgia in the beginning of Boreal. This center appeared independently and was primary for other centers of such technology in the Crimea, on Lower Don region, in North-Western Black Sea region.
