The Gentbrugge Formation (Dutch: Formatie van Gentbrugge, abbreviation: Ge; named after the town of Gentbrugge in East Flanders) is a geologic formation in the west of Belgium. The formation crops out in East Flanders and West Flanders and also occurs in the subsurface of the Province of Antwerp. It consists of marine clay, silt and sand, deposited in the shallow sea that covered northern Belgium during the Ypresian age (around 50 million years ago, part of the early Eocene).^[1][2]
