Integrating High-resolution Shear Wave Seismics and Outcrop Data:A Case Study from Northern Germany

Shear wave seismic surveys allow a detailed assessment of the facies architecture and structural style of the Emme Delta in northern Germany. We combine outcrop and seismic data. The individual architectural elements that form the delta body were defined on the basis of their external geometry and the internal reflector pattern. Outcrops and borehole data were used to relate the seismic facies to the sedimentary facies. Special emphasize was placed on identifying faults, based on the reflector pattern. Faults are imaged as transparent lines that offset the reflectors. Syn-sedimentary faults can be indentified based on the wedge-shape of the growth strata. The faults have planar to slightly listric geometries and show vertical offsets in a range of 2 to 15 m. They form small graben and half-graben systems, which locally show roll-over structures. The fill of the half-grabens has a wedge-shaped geometry, with the greatest sediment thickness close to the fault.
