Sandimirov S.S. Chemical Composition of Bottom Sedimentary Deposits in Lakes in the Zone Impacted by Atmospheric Emissions from Severonickel Plant. Geochemistry International. 2010, Vol. 48, №11, p. 1148-1153.

CHEMICAL COMPOSITION OF BOTTOM SEDIMENTARY DEPOSITS IN LAKES 1153 metals are oxidized to the surface layers of the BD, and their solubility decreases. This process continuously increases the Fe and Mn concentrations in the surface layers of the BD and results in marsh ores in the form of crusts, which were discovered in the early 1930s in Pagel’ and Moncheozero lakes. The lakes have different sedimentation rates: the lowest sedimentation rate was detected in Pagel’ Lake (0.4 mm/year), and this value for Mocheozero Lake is 0.7-1.0 mm/year. The highest sedimentation rate is typical of Mocheozero Lake: it is close to 2 mm/year. These differences are predetermined by the morpho- metric and hydrobiological characteristics of the lakes (their surface area and depths and biological produc­ tivity), as well as the size of their drainage areas.
