Co source has been determined 
by MagnettechMiniscopeMS400 EPR Spectrometer using individually wrapped, bar code labeled 
BioMax Alanine Dosimeter Films (developed by Eastman Kodak Company).

The age estimation which has been performed for the Kurgan-1 was equal to 5356±199 years 
Uranium content of tooth enamel and dentin has not been measured and taken into account, and re-

Conclusion 
As a result of the excavation of the above-said kurgans it has been revealed that the ancient 
cattle-breeding tribes settling in high mountainous areas possessed extensive pastures still begin-
ning from the Early Bronze Age and formed the cattle-breeding culture there. Consequently, set-
tlements and grave monuments had emerged there. Also, it was revealed that starting from the Early 
Bronze Age until the beginning of the Iron Age the people widely used the kurgan setting tradition 
there and the fact that this tradition was widely spread in a vast area. The result of the analysis of 
the tooth samples taken from the Yardimli district was dating
