Rassmatrivaetsya geologo-geomorfologicheskoe polozhenie i facial'nye usloviya nakopleniya tolsch peschanyh nanosov primorskih nizmennostey morey - Laptevyh i Vostochno-Sibirskogo, a takzhe nizmennyh akkumulyativnyh ravnin Severnoy i Central'noy Yakutii. Ustanovleno, chto ih genezis sopryazhen s morskim transgressivno-regressivnym ciklom. Privodyatsya novye geomorfologicheskie, geohronologicheskie i paleogeograficheskie svidetel'stva o edinom vremennom koridore aktivizacii flyuvial'nyh processov v Severnoy Azii i Severnoy Amerike v pozdnem neopleystocene. Eti processy ohvatyvali ne tol'ko poberezh'e Severnogo Ledovitogo okeana i nizmennye ravniny Severnoy i Central'noy Yakutii, no i vodoemy Central'noy Azii, v chastnosti basseyn vysokogornogo ozera Issyk-Kul'. Zdes', kak i na poberezh'e vostochno-arkticheskih morey, vsled za povysheniem urovnya vodoema nablyudalos' posledovatel'noe cheredovanie ciklov sedimentacii - ot basseynovogo namyva bar'ernyh akkumulyativnyh form v vide peresypey, petlevidnyh kos i barov - do nakopleniya za etimi akkumulyativnymi obrazovaniyami lagunno-ozerno-bolotnyh faciy formirovanie kotoryh na Issyk-Kule v otlichie ot shirot Yakutii, ne soprovozhdalos' lish' otlozheniem ledovogo kompleksa. Hronologicheskie ramki flyuvial'nogo cikla, sudya po radiouglerodnym opredeleniyam i OSL-datam issledovannyh otlozheniy, ohvatyvali period: ot 27-29 do 10 tys. l.n.
