The new tectonic map of the Alps is based on the combination of purely structural data with criteria regarding paleogeographical affiliation and/or tectonometamorphic evolution. The orogenic evolution of the Alps is discussed using a combination of maps and paleogeographical reconstructions. It is proposed that the Alps are the product of two orogenies, a Cretaceous followed by a Tertiary one. While the former is related to the closure of an embayment of the Meliata ocean into Apulia, the latter is due to the closure of the Alpine Tethys between Apulia and Europe. The along-strike changes in the overall architecture, as for example revealed by geophysical-geological transects, are by far more substantial than hitherto believed. It appears that the Alps are still far from being over-investigated, as is demonstrated by many surprising recent findings based on field geology, laboratory results and geophysical methods of deep sounding. ZUSAMMENFASSUNGDie neue tektonische Karte der Alpen basiert auf einer Kombination von strukturellen Daten mit Kriterien der paläogeographischen Zugehörigkeit und/oder der tektono-metamorphen Entwicklung. Die Orogen-Entwicklung der Alpen wird anhand einer Kombination von Karten und paläogeographi-schen Rekonstruktionen diskutiert. Hierbei wird vorgeschlagen, dass die Alpen das Produkt von zwei Orogenesen sind: einer kretazischen, gefolgt von einer tertiären. Während erstere auf die Schliessung des Meliata-Ozeans zurückgeführt wird, ist letztere das Produkt der Schliessung der Alpinen Tethys zwischen Apulia und Europa. Die Änderungen in der Architektur der Alpen entlang dem Streichen sind weit wichtiger als bisher angenommen, wie am Beispiel geologisch-geophysikalischer Querschnitte illustriert wird. Es scheint, dass die Alpenforschung immer noch für Überraschungen gut ist. Dies zeigen neue Ergebnisse, die auf Feldforschung, Labormethoden und neue Methoden der geophysikalischen Tiefenerkundung abgestützt sind.

“…Many of these sediments are typical flysch sequences of turbiditic origin (Caron et al 1989), e.g. the Niesen flysch or the Gurnigel and Schlieren flysches (that have a North-Penninic homeland according to a recent proposition of Trümpy 2006 that we accept willingly), while in other cases they can result from more complex deposition mechanisms combining gravity and bottom currents and can also incorporate detrital calcareous formations, e.g.…”

In Central Switzerland (Wägital and Iberg) the North-Penninic flysch deposits seem to start slightly earlier (Campanian) but still during the second half of Late Cretaceous (Winkler et al 1985;Trümpy 2006).…”

The Teggiolo zone: a key to the Helvetic–Penninic connection (stratigraphy and tectonics in the Val Bavona, Ticino, Central Alps)

The Teggiolo zone is the sedimentary cover of the Antigorio nappe, one of the lowest tectonic units of the Penninic Central Alps. Detailed mapping, stratigraphic and structural analyses, and comparisons with less metamorphic series in several well-studied domains of the Alps, provide a new stratigraphic interpretation. The Teggiolo zone is comprised of several sedimentary cycles, separated by erosive surfaces and large stratigraphic gaps, which cover the time span from Triassic to Eocene.

“…Rather than discussing a South Penninic (Piemont-Liguria) origin of the Rhenodanubian flysch, as suggested by Kurz (2005), we would like to propose that Wäggitaler, Schlieren and Gurnigel flysch units of the Swiss Alps, in which sedimentation does not stop before Eocene times, could also belong to the Valais oceanic domain (following a suggestion by R. Trümpy, written communication), contrary to common belief amongst Swiss geologists since the publication of Caron et al (1989). We regret that we did not have the courage to propose this alternative view in our tectonic map, which we now consider by far more logical.…”
