Abstract: | Differences in the chemical composition of soils developed from sorted sands of different origins are revealed. The iron-illuvial
podzols on rich glaciofluvial and marine sands are characterized by well-pronounced Al-Fe-humus differentiation of the Si,
Al, and Fe in the soil profile. These soils are relatively similar in their bulk elemental composition. The difference between
them is seen in the degree of differentiation of the soil profiles; it is stronger in the soils developed from glaciofluvial
deposits. This is particularly true with respect to the oxalate-soluble iron and aluminum hydroxides. The deposits derived
from the red-colored Tersk sandstone and processed by the sea (in the coastal zone of the White Sea) have the poorest chemical
composition. In the soils developed from them, the differentiation of oxalate-soluble compounds is slightly pronounced (for
Fe) or completely absent (for Si and Al). These soils can be classified as podzolized ferruginous red-colored psammozems (within
the order of poorly developed soils) with the following horizons: O-Ce-Cf-C. The Ce horizon has the features of podzolization,
and the Cf horizon has some features attesting to the illuvial accumulation of Fe. The profile of these soils inherits a reddish
tint from the parent material. |
