Figure 8. Interpreted seismic profile across the carbonate buildup, see Figure 2 for location. The Upper Jurassic interval shows strong compaction sag of the bedded deposits, which surround the compaction-resistant organic buildup (blue dotted lines). Effect differential compaction is also compaction-resistant organic buildup (blue dotted lines). E ff ect di ff erential compaction is also observed observed within the lower parts of the Upper Cretaceous interval (green dotted lines). within the lower parts of the Upper Cretaceous interval (green dotted
