p.62: The prominent geographic position of the Gotthard region as one of the preferred north–south connections across the Alps has attracted geologists and naturalists for centuries. Different tunnel projects have produced a large amount of reports on the lithological, tectonic and geotechnical characteristics of the rocks of this area. Exhaustive bibliographies, in particular from a historical point of view, can be found in LABHART (1977) and in the explanatory notes of the map sheets of the Geological Atlas of Switzerland 1:25000 (LABHART 2005, WYSS & ISLER 2007, 2011, NIGGLI et al. 2008, LABHART & RENNER 2012, VÖGELI et al. 2013, BIANCONI & STRASKY 2015). Of particular interest for the lithological description of the crystalline rocks of the Gotthard Nappe are the fundamental studies of P.Niggli’s students in the first half of the 20th century (AMBÜHL 1929, WINTERHALTER 1930, HUBER 1943, NIGGLI 1944, OBERHOLZER 1955, FEHR 1956, HAFNER 1958, STEIGER 1962). Their work served as a basis for the review of MERCOLLI et al.(1994), much of which was in turn reutilised for the present map sheet. In addition to the description of the lithostratigraphic relationships, the rocks of the Gotthard Nappe have been the focus of more recent studies on the Alpine metamorphism and tectonics (see p. 94 ff.). Table 3 is taken from MERCOLLI et al.(1994) and visualises the correlation of the pre-Mesozoic rock types described in the older literature with lithostratigraphic units of MERCOLLI et al.(1994) used for the present map
