Sequence stratigraphic interpretation of the Upper Jurassic based on the fully cored research well Moosburg SC4. Sequence 1 (S1) is mainly dominated by dark, clay-rich mudstones D. Sequence 2 (S2) is largely comprised of dolomitic sponge-thrombolite floatstone, which is considered an important reservoir facies C. During the HST of sequence 3 (S3) a shift to shallow water and partly high-energy facies is observed as the sponges are gradually replaced by corals B. Bioherm/reef debris wedges, extending several 100’s m into the basin, are frequently observed on the 3D seismic and interpreted as highstand shedding (Schlager et al. 1993). Sequence 4 (S4) shows multiple exposure surfaces (A) and dolomitic intervals and marks a gradual change into a terrestrial system with the presence of silt and sandstone
