Abstract

Numerical information on unconsolidated geological materials has use in many geotechnical, hydrogeological and forestry appHcations. Glacial geological mapping, is not based on numerical data, however, but on the morphogenetic interpretation of landforms and visual field checking. The average sampling density for basic map (1 : 20000) production in Finland is less than one sample/km2. One of the practical problems in the mapping is that till, the most common glacial sediment type, has no unambiguous numerical definition, and the conventional dso-classification does not necessarily correspond to the genetic classification. There is a need, therefore, for fast techniques for field data collection, which are consistent with the textural characteristics of glacial materials and allow the differentiation of tills.
