 A1 - Microbial carbonate reservoirs architecture: from depositional facies to seismic scale geometries in the Triassic of the Dolomites (Italy) | Pre-meeting Trips | IAS 2019 Rome
Line drawing and facies mapping of the Mt. Feudo transect exposing a carbonate platform to basin transition (Gattolin et al., 2009 and Preto et al., 2011).

Carbonate platforms represent economically significant targets for hydrocarbon exploration and production.
Such types of reservoirs are liable to display a large variability in their characteristics, affecting both performance and economic viability, hence, outcrop analogs can provide key information for their interpretation in the subsurface.
Microbial carbonate platforms, rare today, are common in the Paleozoic and Mesozoic record when they reached considerable size and developed unique and characteristic facies associations and depositional geometries. They form giant reservoirs e.g. in the Paleozoic of the Pre-Caspian area or in the Cenozoic of the Far East.
This field-trip will be held in the Dolomites that feature a collection of microbial Triassic carbonate platforms, with the aim of providing a multiscale understanding of such carbonate systems ranging from depositional facies distribution and architecture to their relations with tectonic setting and climate.
Participants will have the opportunity to visit exceptional outcrops where platforms can be examined from the facies level up to seismic-scale depositional geometries.
The fieldtrip will focus on the Middle-Upper Triassic with key stops in localities such as the Latemar Platform, the Sella Platform and the Cinque Torri-Tofane nearby Cortina d’Ampezzo.

Technical Information

The fieldtrip will be held in the area recently included in the UNESCO world heritage sites and is optimized for 9-18 participants. Walks along medium difficulty mountain trails at 1500-2600 m asl (avg 300 m of topographic elevation difference) are planned. A basic mountain experience, good fitness conditions, no fear of height, hiking boots, rain coat, sun screen, hat, goggles and a light sleeping bag are required. Accommodation is planned in hotels or mountain huts (rifugio). In case of bad forecast the fieldtrip will be rescheduled on outcrops suitable to be visited with adverse weather conditions. The cost include two overnight stays, food and beverage for three days, transportation by minibus and chair lifts, a fast train ticket from Venezia-Mestre to Rome.
