Kennzahlen für den Feinheitsgrad des Lösses

Ernst Schönhals
On studying the loess, the particle-size distribution is of great importance, as from the variations in its fineness essential inferences can be drawn concerning the eolian sediments. To find out the differences in the fineness one was restricted so far to comparing the single fractions. Of course, this method could not give exact results. The described new method now allows to indicate the degree of fineness by a single factor, the so-called „Kennzahl" („characteristic figure")....
