In this article the technique of the allocation
of the Early Holocene microblade industries to sites with mixed cultural layers
in Central Yakutia (Tuymaada valley) is discussed. This technique is based on
the distribution of common stone material of microliths that are to a great
degree characteristic of the Sumnagin culture. Materials from sites are
associated with the Mesolithic on the basis of technical-typological and
statistical analysis of materials and their comparison with same-age materials
of precisely stratified sites of the Sumnagin Culture of the Aldan and Olekma
rivers. The stone materials of the Sumnagin Culture are based on the maximal
use of blades from which practically all set of industrial products were
produced, except for large cutting instruments. The statistical representation
of microblade tools in the materials from sites is supported to a large degree
by blades and the tools made from them. The prevailing amount of blades in
relation to flakes, blade tools in relation to flake tools, and in some cases
the absence or small amount of ceramics among materials from the sites, also
testifies in favor of early dating. This analysis of the Sumnagin cultural
complex is based on 11 sites located in the Tuymaada Valley, including:
Kapitonovka, Kil’dyamtcy III, Severo-Zapadnaya II, Fermennoe Ozero, Syrdakh VI,
Zernovaya II, Us-Khatyng I, V, Vladimirovka IV, Horo I, III. From about 25
sites where microblades industries are found, additional work has supported an
assumption that the presence of Mesolithic stone materials in these cultural
layers can be proven.
