Earlier investigations along the Dutch-German border in the Buurse-Haarmühle area (South of the town of Enschede) have led to the conclusion of the existence of a Wealden syncline between Bügel and Feldhall (BENTZ). The present auther shows that the occurrence of Wealden is very mucht restricted to the area immediately south of Feldhall, where in the years thirty Lower-Wealden Limestone and serpulite have been quarried. To the west, grey to black shales, with intercalations of fine sandstone, of Liassic and Rhaetian age (unconformably overlying Muschelkalk) occur at shallow depth. Several tens of metres to the east and southeast of the former quarry, grey clay with Cyrena sp. and fishscales of the youngest Wealden (6) occur (also unconformably upon Muschelkalk); these layers dip away under overlying Kohfeld schichten (limnic sands of Valanginian age). Hand, auger reconnaissance in the area, made by the auther, showed un- conformable contacts of Hauterivian, Valanginian, and Wealden 6, respectively, upon Muschelkalk, Serpulite upon Liassic, and Rhaetian upon Muschelkalk.
