The present-day surface of the Netherlands is mostly flat, low-lying land, about half of which would be flooded by the sea in absence of dikes. The underlying geology is fascinating: the country 'has its mountains underground', and is rich in hydrocarbons, coal, salt, groundwater and other geological resources. Geology of the Netherlands is a new, comprehensive reference work, covering both the onshore area and the Dutch sector of the North Sea. The book deals with the stratigraphy and structural setting of Lower Paleozoic to Quaternary sediments, with magmatism and seismicity, and also addresses the geological resources. This book aims to present an up-to-date overview for geologists, engineers and earth science students, and should stimulate the interest of all others who wish to know more about its subject.
