The top peat in middle taiga of the Pre-Ob region represents a highly negative geochemical anomaly of several chemical elements as compared to that in southern taiga located in the middle and upper parts of this region. Obviously, due to close location of mountain systems (Altai, Salair ridge, Kuznetsk Alatau) and the aerial dust transfer the top peat in southern taiga is enriched with the major metals; this process is unachievable for the remote middle part of the Pre-Ob region.
