Vorren, T. O. 1977 06 01: Grain‐size distribution and grain‐size parameters of differcnt till type on Hardangervidda, south Norway. Grain‐size characteristics for different till types on Hardangervidda havc been studied: Basal tills are finer grained than ablation tills: phyllitic basal tills are relatively rich in gravel and clay: basal tills derived from a semiporphyritic granite are poor in clay and have a deficiency of very coarse sand. Of the Folk a Ward's (1957) grain‐size distribution parameters, sorting and kurtosis seem to he the most diagnostic parameters for distinguishing between different types of till. A linear corrclation betwen sorting and the other grain‐size parameters is indicated for the basal tills.
