p.48: The Wendenjoch Formation, previously called “Wendenkarbon” (LABHART 1977 and references therein), consists of a thin, few metres to tens of metres wide, discontinuous band of dark-coloured to black clastic sedimentary rocks of assumed Late Carboniferous age. It extends from the Jungfrau area in the west to the Urner Reusstal in the east. ROHR (1926) gave a detailed stratigraphic description (see ROHR 1926, Fig.4). Classical outcrops are in the area of Tierberg, located between Titlis and Grassen. The metasedimentary rocks of the Wendenjoch Formation are frequently strongly deformed; they separate the polycyclic metamorphic basement units of the Innertkirchen-Lauterbrunnen Zone in the northwest from that of the Erstfeld Zone in the southeast. Note that VON RAUMER et al.(1993) associated these rocks to the Erstfeld Gneiss Complex (Tab. 2). This particular tectonic position facilitates differentiation of the Wenden Zone from the Lötschental-Maderanertal Zone more to the south.
