The location of the data is shown in Figure 7. ( a– c) NE–SW-trending seismic lines illustrating the moderately NNE-dipping geometry of the Sørøya–Ingøya shear zone. -Figure 4d: Interpreted (up) and uninterpreted (down) seismic reflection data on the western Finnmark Platform. ( d) NW–SE-trending seismic line showing major thickness variations of the Sørøya–Ingøya shear zone related to Devonian–Carboniferous core complex exhumation ( Koehl et al., 2018a) and to Caledonian reworking into NE–SW-striking folds. -Figure 5a: Zoom in interpreted (up) and uninterpreted (down) seismic data on the western Finnmark Platform. The location of the data is shown in Figure 6. ( a) Zoom in a NE–SW-trending seismic line showing numerous SSW-verging folds and associated brittle thrusts with top-SSW offsets within the western portion of the Sørøya–Ingøya shear zone. Triangular-shaped packages in the upper left corner are interpreted as deformed foreland basin deposits. -Figure 5b: Zoom in interpreted (up) and uninterpreted (down) seismic data on the western Finnmark Platform. ( b) Zoom in a NE–SW-trending seismic line showing sigmoidal packages of Z-shaped reflections respectively interpreted as antiformal thrust stacks and duplexes within the Sørøya–Ingøya shear zone. -Figure 5c: Zoom in interpreted (up) and uninterpreted (down) seismic data on the western Finnmark Platform. ( c) Zoom in a NE–SW-trending seismic line showing the eastern portion of the Sørøya–Ingøya shear zone, which bends back into a NNE-dipping orientation. Most folds within the shear zone display a vergence to the south-southwest indicating top-SSW movements. -Figure 5d: Zoom in interpreted (up) and uninterpreted (down) seismic data on the western Finnmark Platform. ( d) Zoom in a NW–SE-trending seismic line showing symmetric folds in shallow basement rocks in a major NE–SW-striking syncline possibly consisting of rocks equivalent to the Magerøy Nappe (MN; upper right corner), northwest-verging folds in the northwestern limb of the major syncline (left hand-side), and southeast-verging fold structures in the southeastern limb of the major syncline (lower right corner). -Figure 6a: Interpreted seismic reflection data on the eastern Finnmark Platform. The location of the data is shown in Figure 7. ( a) Intra-basement N–S- to NE–SW-striking Caledonian folds. The data show dominantly symmetric folds.

( b) NNE-dipping ductile shear zone consisting of planar mylonitic surfaces and SSW-verging folds indicating transport direction towards the south-southwest. Notice the mild reactivation of the shallow portion of the thrust by a late Paleozoic listric normal fault. A different color scheme was used to enhance the contrast and better highlight the structures described. -Figure 7: Map showing the depth surfaces (in milliseconds TWT) of the main two Timanian thrusts on the Finnmark Platform. Notice the correlation of major synforms and antiforms observed in the field onshore and on onshore–offshore magnetic data (plain and dashed pink lines) with folding of the Timanian thrusts on the Finnmark Platform in map view identified via seismic mapping (depth surfaces). The map includes major faults from Figure 1. For abbreviations, see Figure 1b. -Figure 8: Bathymetric and topographic data onshore Finnmark and nearshore fjords.

( a) Deposition of sedimentary rocks of the Kalak Nappe Complex, possibly in a foreland basin associated with the Grenvillian–Sveconorwegian Orogeny at 1050–910 Ma and their partial migmatization and intrusion by tonalites at ca. 980 Ma.
