Description :
In the past 4 000 years, Luvisols with a clearly differentiated profile have developed on kurgans of the Bronze Age under beech and oak stands in humid climatic conditions of the foothills of the North Caucasus. The great height of the kurgans (up to 10 m) and their homogeneous composition (the kurgans were constructed of Chernozemic soil and are underlain by Chernozem) make it possible to study the direction and rate of pedogenetic and diagenetic processes acting at a considerable depth. In these kurgans, deep soil features are represented by calcite, gypsum, and iron concentrations. These deep soil processes differ from soil processes in longer characteristic times. They represent the first stage of the development of the weathering mantle.
