Maldegem Formation : ウィキペディア英語版 | Maldegem Formation The Maldegem Formation ((オランダ語:Formatie van Maldegem); old name: Kallo Complex) is a geologic formation in the Belgian subsurface. The formation consists of alternating marine clay and sand strata, deposited during the late Eocene. The Maldegem Formation crops out in the provinces of East-Flanders and West-Flanders and in the area between the Zenne and Dender rivers. In the northern parts of Flanders it forms an up to 50 meters thick sequence in the subsurface. Further south and to the east (in the Campine of Antwerpen) the formation pinches out and can be only a few meters in thickness. ==Lithology== The Maldegem Formation is an alternating sequence of grey glauconiferous fine sands and greyish blue glauconiferous heavy clay. It was deposited during the late Lutetian and Bartonian ages (between 42 and 37 million years old).
