Duration: 3 days 

Departure place, date and time: The trip will depart daily from Selva di Val Gardena and return there in the evening.  

Transportation: Bus 

Accommodation: Participants are responsible for their own accomodation in Selva di Val Gardena. 

Number of participants: minimum 15, maximum 30 

Conditions: moderate mountain hike with whole day walks (intermitted by outcrop descriptions) in Alpine terrain. Warm and waterproof coating and walking boots are recommended. 

Cost: 195 € (includes transport, lunch breaks and guidebook) 

Meeting Point: Conference Venue – Case di Cultura, Selva

Departure in the mornings: 09:00 hrs

Description of excursion:

The first day of the field trip focuses on the sedimentary response of the end Permian mass extinction and the time of recovery in the Lower Triassic. Along the parastratotype section of Bulla/Pufels in the Gröden valley detailed magneto- and chemostratigraphy enable correlations of cycles and sequences in the Tethys area. This should provoke a discussion on eustatic sea level changes and climatic changes.

The second day is dedicated to the famous, traditional Frötschbach-section with a typical southalpine Triassic development. Discussion focuses on the reorganisation of plate tectonics in the Anisian and controversial interpretations about the violent tectono-magmatic event in the upper Ladinian. Seiser Alm and Schlern show impressively a well preserved palaeoslope. We walk along the palaeoslope on the Tourist path from basin to the top of the platform.

Day 3: Crossing the platform toward east we will see well preserved topset facies, with interfingering of lagoonal facies and reef plate (“coral garden”), as well as Upper Ladinian and Carnian carstification and local soil sections with bean ore. The last mega-outcrop of the excursion is the impressive palaeoslope section from the Rosszähne carbonate platform down to the Mahlknechtwall toe of the slope. Sea-level or tectonically forced cycles show the interfingering of prograding reef tongues with Cipit bolders and terrigenous volcaniclastic sandstones and conglomerates derivating from a volcanic island in the SE.

Registration will be performed through the conference registration system.

Excursion to Seceda – Stratigraphy and Time

Topics:

With its excellent views of the Permian - Triassic stratigraphy, including a spectacular Middle Triassic platform-basin setting, the excursion to the Seceda peak in Val Gardena is an ideal introduction to the geology of the Dolomites (weather permitting).

The pelagic carbonate succession of the Buchenstein Formation (ca. 75 metres thick) will be examined in detail for its sedimentary constituents and conspicuous bedding patterns, calibrated by numeric age data (interbedded volcaniclastic layers). Along the excursion route a portion of the basinal succession is replaced by slope breccias of the rapidly expanding Geisler carbonate platform. The top of this high-relief platform eventually reached a level more than 800 metres above the coeval basin floor. The evolution of the platform-basin system was then interrupted by a short episode of vigorous volcanism whose onset and early stages can be observed at Seceda.  

The Seceda Coring Project launched in 1998 let to the recovery of a continuous core from the Buchenstein Formation. Sedimentological and stratigraphical studies of core and outcrop sections have yielded a rich dataset for a close to 5 m.y. long stratigraphic interval straddling the Anisian-Ladinian stage boundary. These results are crucial for the still ongoing dispute about the coeval Latemar platform cycles. The excursion to Seceda provides an up-to-date summary of the stratigraphic constraints and shall revive the discussion about the nature(s) of stratigraphic cycles in this unique basinal and platform setting.

Registration will be performed through the conference registration system.

Sella Platform: Triassic stratigraphy and platform-to-basin geometries

Fieldtrip Leader: Maria Mutti (University of Potsdam)

Position: Pre-meeting

Duration: 1 day

Departure place, date and time: The trip will depart  from Selva di Val Gardena in the morning and return there in time for the beginning of the Conference

Transportation: Bus and cable cars

Accommodation: Participants are responsible for their own accomodation in Selva di Val Gardena.

Number of participants:  maximum 30

Conditions:  The excursion will visit several localities around the Sella massif.  The first stop will be at Passo Sella, followed by a few other stops along the road on the way to Passo Pordoi.  There we will take a cable car bringing us up to an altitude of about 3000 meters. We will take short walks around the cable car station and descend again by cable car.  For those who wish to experience more alpine geology, it will be possible to descend by foot along an official trail (ca 1.5 hours), if the weather will allow it. We will retun back to Selva di Val Gardena by bus, in time for the beginning of the Conference. The weather in October may be chilly, requiring adequate dressing and moderate trekking boots. If you wish to descend back to the Pordoi station by foot you will need serious trekking boots.

Topics:

During this trip we will visit a few classic localities around the Sella Massiv, which with its excellent exposures of the Triassic stratigraphy and platform-to-basin geometries, provides an ideal setting for an introduction to the geology of the Dolomites and to experience first-hand seismic-scale geometries in the field.

During the trip we will look at carbonate platform, slopes and basins . We will start with an overview of Ladinian and Carnian platforms and slopes. We will then examine Carnian basinal deposits and progradational foreslope facies, including Cipit boulders.  Spectacular outcrop geometries will give the possibility to see seismic-scale clinoforms and to examine first-hand the stratigraphic relationships between shelf, slope and basinal deposits around the Sella platform.  We will then walk around the area on the platform top (Sass Pordoi) to enjoy a wonderful panoramic and geological overview of Dolomites  and to look at peritidal strata of the Dolomia Principale .

Registration will be performed through the conference registration system.

Meeting Point: Conference Venue – Case di Cultura, Selva

Departure in the morning: 08:30 hrs

Description of excursion: 

The excursion will focus on Triassic carbonate buildups and coeval basinal units, Anisian to Carnian in age. High relief carbonate platforms will be visited, together with low-relief ramp systems. In detail, we will discuss the start-up, growth and demise of different generations of carbonate platforms, their internal architecture and the changes of carbonate factories. Sedimentary facies will be examined from outcrop to seismic scale and framed into a high-resolution chrono- and sequence stratigraphic scheme. 

The first day of the field trip focuses on Anisian to Carnian depositional sequences framing continental, shallow, and deep-water marine sediments around the Mt. Cernera area. After a general view of the depositional systems, ascent to Passo Giau and hike to Forcella Giau, where will look at the back-stepping geometry of the platform margin and outcrops of basinal sediments covering the drowned carbonate slope. The following evolution of post drowning deep water carbonates and the onlapping basinal siliciclastics and volcaniclastic deposits are exposed along the trail. In Forcella Giau-Lastoi di Formin area, an overview of an Upper Ladinian - Lower Carnian carbonate system will be presented, with a close view of toe-of-slope deposits. 

The second day is dedicated to the large-scale geometry of Upper Triassic carbonate platforms of Lagazuoi and Tofane area and to the temporary demise of the microbial carbonate factory linked to the so-called Carnian Pluvial Event (or Phase). In this area, superb outcrops allow the detailed reconstruction of the infilling phases of previous basins trough the deposition of a mixed carbonate–siliciclastic succession and the change from high relief flat topped platform to low-relief ramp depositional profile. The response of carbonate to mixed depositional systems during a climatic shift from arid to humid, and back to arid conditions will be analysed in detail, as well as the timing of platform demise and recovery with respect to relative sea level change and other environmental forcings.

Registration will be performed through the conference registration system.
