GPR and marine seismic imaging of carbonate mound structures in Denmark and Southwest Sweden: A case study of imaging structures at different scales

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.
