Abstract

This is a comment on the publication by Ivanov et al. (2015) on catastrophic outburst of Lake Baikal and provenance of the Palaeo-Manzurka sediments based on U-Pb dating of detrital zircons. The Paleo-Manzurka river system influenced largely the Baikal discharge and the lake level in general. The suggested model predicting the origin of the Manzurka sediments by catastrophic landsliding and related megaflooding in the Late Pleistocene disagrees with geological and biostratigraphic constraints. However, the paper raises important problems which require further research. ARTICLE HISTORY
