The most "arid" properties are found in the paleosol buried last in the studied pedo-
chrono-sequence (pit Es4b): the color of the humus horizon is the lightest, the profile is
most enriched in carbonates, there is the highest content of exchangeable sodium and
magnesium in the composition of exchangeable bases, the lowest magnetic
susceptibility and the maximum amount of gypsum in the second meter of the profile.
During the indicated time-span of the kurgan construction, Haplic Chernozems Loamic
(soils under the first, second and third kurgan constructions) evolved to Calcic Chernozems
Loamic (soil under the fourth kurgan construction).View entire presentation
