Introduction. The paper deals with the issue of pressure blademaking emergence chronology in the North-Western Caucasus. The possible paths of the innovation diffusion are discussed.

Materials and methods. The study of the lithic technology is based on the materials from the Early Holocene layers of the Dvoinaya Cave and the Chygai Rockshelter. The series of AMS dates were obtained for the layers. The earliest use of pressure blademaking was revealed in the layer 4/5 of the Dvoinaya Cave and the layers 3-5 of the Chygai Rockshelter dated to 11,3–8,5 cal kyr BC and 11,1–8,5 cal kyr BC respectively.

Results. The full technological context of the bladelet and microbladelet production with the use of pressure was revealed at the Dvoinaya Cave. The blanks were produced from the conical cores with faceted platforms. In layers 3–5 of the Chygai Rockselter the pressure bladelets and microbladelets were discovered. In both cases the metrics of the pressure produced blanks indicate the use of Mode 3 of the pressure technique (pressure with the use of short crutch in a sitting position).

Discussion. We don’t consider possible the diffusion of the technique from the Elbrus region of the North Caucasus as there were two technologically distinct traditions that were partly synchronous. The lower chronological range of the Mode 3 pressure emergence in the North-Western Caucasus roughly coincides with the Early Mlefaatian and the Nemrikian in the south and the Early Butovo in the north. The possible intermediate industries dated to the Early Holocene have not been discovered so far in the neighboring regions to the south or to the north of the North-Western Caucasus.

Conclusion. The early timе of the complex mode of the pressure technique emergence in the North-Western Caucasus is indicative of the external adoption and an extremely fast pace of the innovation diffusion in the Early Holocene. © 2023. This work is licensed under a CC BY 4.0 license.
