We studied the composition of the material of kurgan's earthen constructions (EC) and
cements of stone constructions (SC).
In direction from the first to the fourth ECs, the content of organic carbon decreases and
carbonate carbon, magnetic susceptibility, LOI (loss of ignition) increases.

The cement of SCs is characterized by comparatively high content of organic
and carbonate carbon, high values of magnetic susceptibility and LOI.
There are the higher amounts of particle size fractions <0.01 and <0.001 mm
in the cements of SCs as compared with the material of ECs.
