Soil formation on seaboard sands of the White Sea (the Kola peninsula)

Quaternary deposits of Kandalakshsky and Tersky coasts of the White Sea are represented by marine sediments enriched by eluvium of Tersky redcoloured sandstones sorted by the sea. Granulometric composition of these rocks and soils formed on them are characterized by predominance of one sandy fraction - fine sand and the almost complete lack of coarse sand. The rocks containing eluvium of Tersky sandstone have poor chemical composition (the content of silica - 75-80 %). The intensity of profile differeniation in chemical composition of the illuvial-ferraginous podzolah formed on the rocks is reduced with the increase of eluvium of Tersky sandstones in the composition of these soils. Sandy soils - psammozemy with an undifferentiated profile - have been formed on wind deposits undergone forest reclamation and seaboard sands with thinning natural growth. Illuvial-fermginous podzoly buried under lowpowered layer of sand has saved an alfegumusovy profile inherent to this type of soil. In the superficial layer any signs of eluvial-illuvial redistribution of the chemical composition are absent.
