PRE-CONFERENCE FIELD TRIP
The pre-Conference field trip will be 3 full days long. We will meet in Bressanone (Brixen) the evening before the field trip, and we will arrive in Riva del Garda the evening before the start of the conference, in time for the ice-breaker party. We will visit: (i) the Austroalpine basement exposed along the western termination of the Tauern Window, one of the main tectonic features of the eastern Alps; (ii) the Periadriatic Fault System, one of the major faults of the European Alps; (iii) the Permian-Triassic metasedimentary cover of the Austroalpine domain, in the locality where Déodat de Dolomieu first collected samples of calcareous rocks later recognized as a new carbonate mineral (Dolomite, 1792); and (iv) the world famous Mesozoic stratigraphic succession of the Dolomites.
Field leaders: Marco G. Malusa' and Stefano Zanchetta
Detailed Program:
On Thursday 31 August, those flying to Verona will be picked up by bus at Verona “Valerio Catullo” Airport at ca. 3 pm. Participants arriving by train from the south will be picked up at Rovereto railway station at ca. 4 pm. For those arriving directly at the Bressanone railway station, the hotel is about 10 minutes walk (ONTHEGO Agency will contact you by email to know your place of arrival).
We will reach the hotel in Bressanone in time for dinner. We will stay in the same hotel for three nights. The hotel will provide accommodation in single/double rooms and full board with packed lunch for the entire duration of the field trip.
Pictures:
Day 2: (a) The double-dome structure (Tux and Zillertal Antiforms) of the western termination of the Tauern Window in the Vizze Valley (Vipiteno, BZ). View towards W from the Vizze Pass. TUX: Zentral Gneiss of the Tux gneiss; P-T: Permian-Triassic metasedimentary cover of the Tux; J: Jurassic metasedimentary cover of the Tux gneiss; Glockner nappe (calcschist and ophiolites); AU: tectonic klippe of Austroalpine cover.
Day 1: The Meran-Maul Fault (Periadriatic Fault System) in the Pennes Pass area (BZ). Austroalpine paragneiss of Variscan age are thrusted over the Early Permian Brixen Granite intruded in the Southalpnine domain. Oligocene Tonalites are sheared as tectonic slices within the fault zone.
Day 2: (b) The Tribulan (3097 m) in the Fleres Valley (BZ) viewed from South. The Permian to Triassic metasedimentary cover of the Austroalpine domain is entirely represented on the SW face of the Tribulaun (the “Basal Conglomerate” is outside the image, at the base of the rock face. This is the locality where Déodat de Dolomieu collected in the 1972 several samples of a calcareous rock that was later determined by Nicolas de Saussure as formed by a new carbonate mineral: Dolomite.
Day 3: The North and North-East face of Sassolungo (Langkofel, 3181 m) in the Gardena valley (BZ). The Ladinian-Carnian boundary is exposed along the stratigraphic boundary between the dolostones of the Rosengarten Fm. and the Sella subgroup. Both belong to the Sciliar Group.
