From: Giant paleo-seafloor craters and mass wasting associated with magma-induced uplift of the upper crust

Figure 12

(a) Regional 2D seismic line showing forced folds and magmatic intrusions in the study area. The seismic line runs between the Solsikke and SMA areas. In addition, the figure shows evidence for (b) local uplift caused by magmatic sill emplacement under craters, and (c) an example of a vertical fluid-flow structure within the Naust Formation, revealing that vertical fluid seepage is a common phenomenon on the modern seafloor. (d) Example of a hydrothermal vent complex below a crater, a character providing evidence for protracted fluid flow in the study area. (e) Regional uplift related to basin evolution and dynamics. Onlapping reflections above the Brygge Formation show that the region was uplifted during the Miocene.
