(Table 1) Calcium carbonate content of boulder clays sampled along the baltic coast of Schleswig-Holstein, Germany

The carbonate contents in the boulder clay ('Geschiebemergel') of abrasion cliffs were investigated along the Baltic coast of Schleswig-Holstein, northern West Germany. The calcareous boulder clay and stratified drift in the cliffs are interbedded with compressed thrust sheets of Cretaceous limestone, Tertiary Tarras clay, and Eemian clay. According to chemical analyses of 173 boulder clay samples, the amount of carbonate varies mostly between 6 and 17%. Owing to the small number of samples no definite conclusion could be drawn on the distribution of Danish Cretaceous limestones in the boulder clay, nor on the different directions of movement of Weichselian glaciers.
