The paper presents data on the chemical composition of Late Pleistocene-Holocene sediments in the Gakkel Ridge according to data on sediment core PS 70/306-3, offers a hypothetical litho-stratigraphic model, and provides data on chemo-stratigraphic horizons distinguished based on the distribution of carbonates, organic carbon, metals (Fe, Mn, Cu, Zn, Co, Ni, V, Pb), As, and P in the core. Chemical transformations of sediments at the redox barrier are discussed, along with relations between the composition of the sediments and the facies sedimentation conditions.
