Eastern Structural elements from NAG-TEC: Northeast Atlantic Geoscience Tectonostratigraphic Atlas. This dataset contains the basins and highs along the margins and within the Jan Mayen microcontinent and contains information about the ages, the hierarchy between the structural elements and origin of data. For further information see https://data.geus.dk/nagtec/home.

Two profiles are shown. The first is an ordinary cross section through the the 3D model. The second (along the same line) shows the amount of petroleum generated in the shales selected for this study.
