De Zandmotor versus het strand van Hoek van Holland: opvallende verschillen in de vondstfrequentie van fossiele kleppen van bivalven geven informatie over de geologische geschiedenis van de zandwingebieden

A comparison between the frequency of occurrence of fossil valves of bivalves from the Zandmotor and the beach of Hoek van Holland (province of Zuid-Holland, The Netherlands) is made. Both locations are reinforced with sediments dredged from the North Sea Eurogeul area from locations close to each other. Frequency of occurrence of most species differs significantly between the locations. Possible causes are considered and conclusions about the depositional environment are drawn based on the differences.
