This work is devoted to the assessment of the Upper Paleolithic sites of the Northern Tien Shan. Materials and methods. Plains and foothills of Kazakhstan occupies a large western part of Central Asia and stretches from the Caspian Sea in the west to the Altai Mountains in the east. There are many Paleolithic sites, the vast majority of which are open-air (surface) sites. Recently several multilayer Upper Paleolithic sites have been discovered in the Northern Tien Shan. Among them are the sites of Maibulak, Rakhat, Uzynagash 1–3, Saryzhazyk and some others. The sites have been studied intermittently since 2004. A new research phase began in 2018. Results and discussion. The sites are located in similar geomorphological conditions. The cultural layers of the sites are nested in loess-like loams covering the northern foothills of the Zailiysky Alatau Range. Most of the cultural layers are interpreted as habitation levels with preserved hearths, burn spots, charcoal spots...

The study considers the isotopic composition of organic carbon and the content of n-alkanes, not previously analyzed in this area. Both these parameters indicate the waterlogged conditions of Early Pleistocene soil formation as is also indicated by morphology and magnetic susceptibility values. The reconstructed landscapes were represented by herbaceous bio-cenoses on hydromorphic soils with prevalence of C3-grasses.

However, these sequences have a low number of studies on their organic matter, such as researches of isotope composition, n-alkane and other biomarkers. Thus, the purpose of the study was to reconstruct vegetation conditions from the Late Glacial to Late Holocene. We used the leaf wax-derived n-alkanes to detect vegetation evolution of the Bryansk Region. The stable carbon isotope composition of organic matter and pedogenic carbonates was carried out for the same aim. Three paleosols (of Lasko, Bølling-Allerød warmings and Holocene second humus horizons) and modern soils of different relief positions were investigated. n-Alkane distribution, as well as isotope composition indicates changes from grassy to woody vegetation during this period. The use of biomarkers such as n-alkanes helps to more clearly interpret isotopic data.

The radiocarbon data have obtained for two interstadial soils: 16500 ± 230 Ki-17 414, 12930 ± 170 Ki-17 413 years BP. The ratio δ 13 Corg for underlying sandy pedosediments varies in range-26.5-27.2 ‰ characterizes relatively humid climate. The most lightweight carbon isotope composition (δ 13 C =-28.4-29.5 ‰) measured for the Holocene second humus horizon, discovered in micro-depressions of Trubchevsk opolye and dating (in its upper part) 2180 ± 60 Ki-17 415 BP, 1650±60 Ki-18775. It is characterized by a high content of phosphorus, including its strong accumulation of organic compounds (635.8 mg/kg P2O5).
