The data files belong to a 3D structural model which covers the Vøring and Møre basins offshore Norway. In addition, a part of the exposed Fennoscandian Caledonides in the south-east and an oceanic crustal domain are covered by the model. The constructed 3D model is 490 km wide and 660 km long with a horizontal grid spacing of 2500 m, and a vertical resolution corresponding to the number of integrated layers. The lithospheric-scale 3D structural model includes 14 layers: (1) sea water; (2) upper Neogene (post-middle Miocene) sediments; (3) middle-upper Paleogene-lower Neogene (pre-middle Miocene) sediments; (4) lower Paleogene (Paleocene) sediments; (5) oceanic layer 2AB (basalts); (6) Upper Cretaceous (post-Cenomanian) sediments; (7) Lower Cretaceous (preCenomanian) sediments; (8) pre-Cretaceous sediments; (9) continental crystalline crust; (10) oceanic layer 3A; (11) high-density zones within the continental crystalline crust; (12) oceanic layer 3B; (13) high-density bodies within the lower continental crystalline crust; (14) lithospheric mantle. The thicknesses of the layers correspond to apparent thicknesses. In addition, data for earth surface topography is provided in the file: 0_Topography.dat. Model coordinates are based on the UTM 33 Zone (Northern Hemisphere) using the WGS 84 datum. The data format is ASCII and contains three columns (X, Y and Z), where X and Y are geographical coordinates (X = longitude, Y = latitude); Z (in m) is thickness of the layer or structural depth (base of layer) or surface elevation. The grid of each layer consists of 196 cells in W-E direction and 265 cells in S-N direction. The grid limits are the following: Xmin = -222590 and Xmax = 267410; Ymin = 6892200 and Ymax = 7552200. The vertical datum of the 3D model refers to the mean sea level. Organisation of data files: Data are organised in two folders (“Bases” and “Thicknesses”); data for earth surface topography (in case of water: sea level) is in the root folder: 0_Topography.dat. The folder “Bases” contains 14 data files ...
