The mineralogical composition of fraction of more then 0,1 mm of podzolic soils of the Kostroma region was studied. One of the debatable versions of finding the boundary between the glacial deposits of the Moscow and Dnieper ages is confirmed. Signs of destructions of minerals are established, this indicates the role of this process in providing mineral elements of the subsurface, which formed on weathered glacial deposits.

Based on publications on the soils of the Northwest Pacific, particularly wide effect of climatic factor on soil formation associated with the influence of the ocean has been established. Together with the amount of liquid atmospheric precipitation, the regime and the intensity of their precipitation play an important role. Heat supply is determined not only by insolation, but also by the wind regime, as well as the presence of warm and cold currents. The scale of the pulsed contribution of sea water salts with sediments is related to the distance to the coastline. In additions, the ornithogenic factor acts on small islands. All this creates variants of soil formation specificity on the characterized islands.
