Record #112047:

Till stratigraphical studies in the Pulju area in northern Finland / Peter Johansson, Jari Nenonen.

Title: Till stratigraphical studies in the Pulju area in northern Finland / Peter Johansson, Jari Nenonen.
Author(s): Johansson, Peter.
Nenonen, Jari.
Date: 1991.
In: Geological Survey of Finland. Special Paper. (1991.), Vol. 12 (1991)
Abstract: Pulju moraines are defined as non-orientated, morphologically annular or curved hummocks. Genesis and depositional mechanisms of till were investigated in 1989, also relation to ice-flow directions. Lowest stratigraphic unit consists of lodgement till, formed during Middle or Late Weichselian in ice-sheet base as it flowed north. Middle unit is basal till, formed as basal melt-out till near margin of ice sheet. Now forms core of moraines. Upper unit is formed from supraglacial material accumulated on ridges in weak areas and in ice fractures.
