We received results of complex palaeoecological research at south-west Barents Sea coast. In Periayarvi 1 settlement (Sredniy Peninsula) discovered by V. Ya. Shumkin in 1994, archeological excavations of two house-structures were performed. We sampled the sequence in the house-structure 16 date to the Early Metal Age and we studied it with archaeological, palynological, geochemical and radiocarbon methods. The sequence in the house-structure 16 settlement include sand layers in the bottom, the upper part consists of slightly decomposed peat. The radiocarbon data obtained from the charcoal sample from the fireplace in the middle of the house-structure is 2920±70 C14 BP, which correlates with result of pollen analysis. According ac to pollen data, the sequence formation started at the first half of the Subboreal period during the spread of tundra vegetation and then vegetation changed to forest tundra while the climate was getting more comfortable for humans. At the Subatlantic period tundra recovers because of temperature drop. The landscape is getting similar to the modern one. According geochemical indications main functional zones of house-structure were distinguished, and that provides necessary information about main characteristics of living conditions. The complex of methods allows to date Periayarvi 1 settlement to the Early Metal Age. In the results we made reconstruction of palaeoenvironmental conditions in the Late Holocene at the Barents Sea coast.
