Geological and hydrobiogeochemical studies carried out in two areas in the Teletskoye Lake basin in the Altai Mountains suggest that geophagy among wild and domestic herbivores in the studied areas develops in mountain-taiga with steppe landscapes on Proterozoic metamorphic rocks near the Paleozoic granitoids with high concentrations of magmatogenic minerals of rare earth elements (REE). This fact is the reason for high concentrations of REE in loose diluvial deposits and glacial deposits adjacent to granitoids, as well as in derivative soils and vegetation. REE concentrations in the vegetation of the studied territories were almost similar to the geophagy sites previously investigated in the Sikhote-Alin. The geochemical specificity of landscapes revealed both in the Altai Mountains and in the Sikhote-Alin may be the cause of REE imbalance in the hormonal system of the body. It forces animals to address the resulting problems with mineral sorbents of the quartz-feldspar-illite-chlorite type which can remove the excess of REE from the body. When selecting these, the animals tend to find sodium-enriched varieties if possible. [ABSTRACT FROM AUTHOR] |
