On two stages of t o Late Pleistocene glaciation at the upper reaches of the Indigirka River (the Elga drainage basin)
Abstract
Most of explorers of the North-East distinguish two glacial epochs-those of Middle and Late Pleistocene. Author's studies at the Elga basin allow to subdivide the Late Pleistocene glaciation into two stages – Ziryanka and Sartan. Ziryanka stage corresponds to the «brown» till and covering it valved clays; «grey» till (lying on the clays) and terminal moraine ridges belong to Sartan stage. There are three groups of glacial cirques corresponding to different glacial epochs: cirques with altitudes from 1100 to 1450 m belong to Middle Pleistocene epoch, those with altitudes 1450-1.850 m – to Ziryanka stage and with altitudes 1950-2100 m – to Sartan stage.
