This article describes how ground-penetrating radar (GPR) measurements and marine seismic data were combined to image the fine- and large-scale geometrical characteristics of carbonate mound structures in Denmark and southwest Sweden (Figure 1) where carbonate mound complexes over structural highs are commonly observed in near-surface limestone layers. The mounds, Upper Cretaceous-Danian (Lower Paleocene) age, represent the late stage of a ∼35 million-year period of carbonate deposition in large parts of northwest Europe (Surlyk, 1997). Carbonate mounds in Denmark and Sweden are similar regarding architecture, spatial distribution, and size.
In the North Sea, contemporaneous limestones form important oil and...
