In the open-pit mine of Grimmen/westerly of Greifswald is placed a Eem Interglacial onlap-sequence upon Warthe-moraine. The gravel and sand accumulations should be autochthonous. The Eem-Sea gave rize to a deep bay intruding on the land of Vorpommern. The deformation of the sediments, including Lias and Eozän, should be older than the two (?or three) Weichsel-morains. The postulated push moraine of Velgaster Staffel does not exist in the Grimmen area.
