ANATOMY OF GROWTH FAULT ZONES IN POORLY LITHIFIED SANDSTONES AND SHALES - IMPLICATIONS FOR RESERVOIR STUDIES AND SEISMIC INTERPRETATION .2.SEISMIC-REFLECTION GEOMETRIES

Interpretation of seismic reflection data across growth faults reveals that many of the small-scale fault geometries recognized in outcrop c an also be interpreted on seismic data. While some fault zones can be interpreted as a single fault plane other faults are made up of bundle s of overlapping fault planes connected hy various hard and soft linka ge geometries. These fault zones can be up to 1 km wide. While the zon es of deformation bands identified in outcrop cannot be detected on se ismic data, the existence of similar fault zone geometries in outcrop and seismic data suggests that the deformation band zonation might als o be similar.
