Abstract
    On the beach, heavy minerals are repeatedly more or less concentrated by tidal currents and by wave or wind action. It is only under particular circumstances that thicker ore layers are formed, which formation according to Wasmund, is conditional upon æolian concentration at the foot of dunes followed by marine dune erosion. This hypothesis is assumed for the typical concentration of heavy minerals, chiefly garnet, on the beach near Bergen (North Holland) and of Goeree (South Holland). During the war years the sea considerably attacked a certain dune area on the island of Vlieland and at a high rate. Here, too, the characteristic garnet layers were found on the beach. These sediments were examined for heavy mineral content and percentage by weight of heavy minerals, and subjected to a grain size analysis, the result being that Wasmund's hypothesis was clearly confirmed. The sedimentation balance method used in the grain size analysis of sediments for differentiation studies presents several advantages over other methods.
