Abstract
На основе спорово-пыльцевого анализа донных осадков оз. Цага-3 выделено 9 биостратиграфических зон и подзон, реконструированы этапы развития растительности в голоцене, которые сопоставлены с климатостратиграфической схемой Блитта-Сернандера. Особенности литологического строения разреза и результаты геохимических исследований предполагают существование массивов мертвого льда в районе оз. Цага-3 вплоть до атлантического времени.
Spore-pollen analysis of the lacustrine sediments of the lake allowed to identify 9 biostratigraphic zones and subzones. Stages of the vegetation evolution during the Holocene were reconstructed and cohered with the periods of the Blytt-Sernander classification. Lithology features and geochemistry results indicate that dead-ice had existed within Lake Tzaga-3 area by the middle of the Atlantic time.
