Distinction between tills and other diamictons based on textural characteristics
Lawrence A. Fra Paulo M. B. Landim, Lawrence A. Frakes · Journal of Sedimentary Research · 1968
Abstract Statistical parameters of the granule-to-clay size-frequency distribution efficiently differentiate till from alluvial-fan deposits and from outwash deposits. Discriminant functions utilizing mean, standard deviation, skewness, and kurtosis also separate the three types of sediment. As a test of the method, samples of fossil mudflow were studied; they plot in the area of alluvial-fan deposits.
