The micromorphological study of quartz grains from the Kysyl-Syr dune massive in the lower reaches of the Vilyuy river included analyses for roundness and dullness and determinations of genetic groups of diagnostic elements on the quartz grain surface. The research results presented in this paper allowed to establish two stages in the formation of the Kysyl-Syr dune complex. During the first stage (begun about 40 ka BP) fluvial processes prevailed. The second stage of sedimentation (Late Neopleistocene – Holocene) is characterized by aeolian sedimentation.
