Alpenseminar by Mjahid Zebari . After the Exkursionswoche break, we had a presentation about Neogene to recent faults in Eastern Alps by Mr. Zebari on 15th of June. He won't join the excursion this year, but he gave a comprehensive views with various methods on new tectonics. The content of the talk include the following. Tectonic map of the Eastern Alps [modi fi ed after Handy et al ., 2010 ]. ( Bertrand et al, 2017 ) Main Faults System - N-S Normal Fault:  Brenner fault,  Katschberg fault - Strike-slip faults:   Sinistral (to the NORTH ): Inntal fault , Salzachtal ‐ Ennstal ‐ Mariazell ‐ Puchberg fault, Mur‐ Mürzf ault, Defereggen ‐ Antholz ‐ Vals fault .   Dextral (to the SOUTH ): Periadriatic fault, Pöls‐Lavanttal fault, Hochstuhlfault, Mölltal fault . Present-day deformation of the eastern Eastern Alps( J. Reinecker 7 W. A. Lenhardt, 1999 ) Present Day Stress Fault plane solutions e...

 Alpenseminar by Julian Welte On the 18th of May, we discussed about the nappe structure of the Northern Calcareous Alps and its disintegration during Miocene tectonic extrusion, given by Mr. Welte. The Northern Calcareous Alps includes the following succession of nappes from north to south, and from bottom to top( see Alpine Tectonics map , purple coloured ): Bavarian nappes (Mesozoic cover), with narrow synclines and anticlines. Toward the south they dip down below the overthrusted Tyrolic nappe complex. Due to their dominant dolomitic lithology, the Tyrolic nappes exhibit internal thrusting and faulting and only minor folding. The Juvavic nappes represent the uppermost tectonic element, overlying the Tyrolic nappes. The nappe complex of the Northern Calcareous Alps (after PLÖCHINGER, 1995). ( GERHARD W. MANDL, 2000 ) Explanation of abbreviations: Northern Calcareous Alps: Juvavic nappes: B = Berchtesgaden nappe, D = Dachstein nappe, SC =...

Alpenseminar by Verena Frey On the 18th of May we learnt about Tertiary magmatism along the prominent Periadriatic Lineament. During the previous seminars we discovered that the Periadriatic Lineament represents an important tectonic feature across the Alps and also plays an important role in controlling many surrounding geological processes, including stress release. Curiously, much Tertiary magmatism seen within the Alps appears to be aligned along the Periadriatic Lineament, as can be seen below: Overview of the Periadriatic Lineament and surrounding Tertiary intrusive bodies, after  von Blanckenburg and Davies, 1995 The Periadriatic Lineament formed in response to dextral movement along the European and Adriatic collisional zone and is often characterised by steeply-inclined mylonitic structures. Age dating of the Adamello pluton has helped constrain the age relationship of magmatism to being syn-collision: Overview of the range of age dating for the A...
