Record #167244:

A mathematical model to explain the effect of comminution, resedimentation and outwashing on the finest fractions of till in four test areas in Central Finland / Jari Mäkinen.

Title: A mathematical model to explain the effect of comminution, resedimentation and outwashing on the finest fractions of till in four test areas in Central Finland / Jari Mäkinen.
Author(s): Mäkinen, Jari.
Date: 2003.
In: Geological Survey of Finland. Special Paper. (2003.), Vol. 34 (2003)
Abstract: Examines proportions of bedrock and preglacial sediment in fine and sand fractions of till in central Finland and effect of outwashing on till composition. Describes mathematical modelling of resedimentation, comminution of rock fragments and other glacial processes, supported by analysis of compositions of natural till and of artificial sand and fine fractions produced by laboratory crushing, abrasion, outwashing and sedimentation. Describes sampling of till known to incorporate preglacial sediments and presents detailed results of geochemical and element analyses. Concludes Weichselian tills of Mertunaoja and Pyhäsalmi contain respectively 83% and 57% of resedimented Quaternary sediments in fine fraction and 87% and 93% in sand fraction.
