The concentration of these objects during the early development stages of the Turkic culture reflects a process of deve-loping traditions in funeral rites with nomads in the late V VI c. B.C.

There are presented the results of field experiments with groups of high-power vibration sources at deep seismic researches on the profiles in the East of Russia. As a result of research there were determined optimum distances of 1-2 m between two vibration sources in the group. There was determined significant role of repeated vibrator sessions and use of different unbalanced masses for various vibration sources in the group for raise of correlogram resolution and raise of signal/noise ratio.
