Abstract
In the Khibinsko-Lovozero district of the Kola Peninsula, the territory is divided into three geochemically different areas. In the background area near Umbozero, both mineral and peated samples contain all rare metals below clark: lanthanides and actinides are leaching heavily from acidic podzolic soils. В in the area of weak geochemical anomaly (near Lovozero), all lanthanides are inherited from the loparite-containing rock, and all actinides - Th: their content is 1.3-5.4 times higher than the clark value. In the zone of a strong geochemical anomaly (on the northern shore of Seidozero and on the
The concentration of lanthanides and actinides is even higher: 4-9 times higher than the clark value. There is an impact of a biological barrier that prevents excessive accumulation of of heavy metals in the mosses of a geochemical anomaly.
