Some remarks on distribution and genesis of palaeoincisions in the East Baltic area

Albertas Bitinas

Abstract


Until the recent time genesis of palaeoincisions is one of the debatable problems among the Quaternary investigators in the East Baltic area. Distribution of palaeoincisions in the East Baltic area is closely correlated with the pre-Quaternary bedrock lithology and permeability as well as with recently active faults. These regularities confirm the theory that most palaeoincisions in this area were formed as subglacial tunnel valleys during catastrophic discharge of meltwaters, due to high pressure conditions beneath the ice sheet.
