Рельеф юго-восточного Призайсанья и некоторые особенности четвертичного осадконакопления

Аннотация

Four stages are distinguished in the relief development in the Zaisan Lake basin, each of them being associated with a complex of built-up surfaces: 1) glacial-fluvioglacial-lacustrine stage ( Kiinzhirian) - the end of the Middle Pleistocene; 2) glacial-alluvial - lacustrine (Katonian) - beginning of the Late Pleistocene; 3) lacustrine-alluvial stage (post-glacial) - the end of the Late Pleistocene; 4) alluvial - the Holocene. Geomorphic structure and the Quaternary sediments distribution suggest general upwarping of the area during the Quaternary, the movement amplitudes decreasing gradually.
