The quaternary geology of the dutch part of the north sea and the exploration of sand and gravel

A survey is given of the results of several geological investigations of the Netherlands North Sea area. The author deals especially with the lithological aspects of the several deposits and indicates further an interpretation of the results. The latter turns out the expected similarity between the geological systems of the western Netherlands and the adjoining part of the North Sea. Some consequences for the exploitation of sand and gravel deposits are indicated.
