ИСТИНА

Paleosols are soils that formed on a landscape during the geologic past. They could be buried, exhumed, or surface and they also include the products of soil transformation in the geological cycles. Paleosols record former landscape features, allowing environmental reconstructions. Paleosols appeared simultaneously with the terrestrial microbial biosphere in the early Pre-Cambrian. The pedosphere develops in line with biological evolution (co-evolution of Life and Soil). The study of paleosols provides evidence for the critical points in the evolution of the Earth’s Geosphere during geologic history: the Great Oxygenation Event, Ice-house and Hot-house biospheres, mass extinctions, glacial-interglacial cycles, etc. Reconstruction of landscape dynamics through the last Interglacial-Glacial cycle may serve as a base for Climate Change forecast.
