Alluvial, aeolian and soil horizons were detected in floodplain deposits of small rivers of Southeastern Transbaikalia. The occurrence of soil horizons in floodplain sediments indicates that they were formed at periods of an enhancement in erosion activity at the end of the dry cold phase and at the beginning of the dry warm phase during the overall course of heat availability and humidification of climate in the latter half of the Holocene. An enhancement in fluvial activity corresponded to the cold humid phase, whereas an intensification of the aeolian process was taking place during the dry cold phase.
