NAGRA Opalinus Clay (…002 - Version 1
FEP 14.1.5 Faults, distribution and properties

The largest features found in the Zürcher Weinland are the Neuhausen fault (oriented NW-SE, maximum offset at Opalinus Clay level 40 m) and the Wildensbucher flexure (oriented W-E, maximum offset at Opalinus Clay level 20 m). Smaller scale features in the Opalinus Clay have been observed by the 3D seismic campaign but are found to be limited in extent with offsets smaller than a few m (no layout-determining faults).
