Submarine unconformity on a hinged shelf margin
Marine onlap of turbidites over ramp marls

The field trip illustrates the Late Eocene-Miocene changes in depositional style of the infill of the Tertiary Piedmont Basin (TPB) in a stratigraphic perspective, relating them to major paleogeographic reorganization linked to Alpine and Apennine tectonics. A variety of depositional systems will be examined including alluvial, marginal marine, shelf and intra-slope and basin-plain turbidites. Outcrop observations will be integrated with photogrammetric models and seismics from time-equivalent buried examples from the area.
Topics covered include:
1) relationships between morphostructural elements and origin of classical sequence boundaries driven by relative sea level falls vs. hinged-margin drowning unconformities driven by hinged accommodation on oversteepened shelf margins;
2) morphologies of deep-water erosion;
3) controls of basin morphology on development of turbidite facies and architecture;
4) petrography of turbidite sandstones and mudstones and implications for origin and source of mud-grade sediments;
5) implications for characterization of analogue plays and reservoirs.

Itinerary

1st day morning: Rome (‘Termini’ railway station) to Milan (‘Centrale’ railway station) train transfer (morning) and car+minivan pick up and transfer (late morning-early afternoon) to the TPB (Tanaro and Bormida Valleys).
3rd day evening: transfer to Curone Valley (eastern TPB).
5th day early afternoon: return to Milan (‘Centrale’ railway station).
Technical Information

The field trip is planned as low difficulty short walk on dirt roads and trails (for longer distance, we will move by minivans and cars) at elevations ranging between 200 and 700 m. Weather conditions in September are generally good, although cold winds and rainy days are possible. Trekking shoes, waterproof clothes, hat and sunscreen are recommended. The basin is also one of the most famous wine-producing regions of Europe and participants will have a great opportunity to explore relationships between geology and grapevine distribution. Accommodation is planned in local country hotels serving local food and wine making for a real taste of the gastronomic heritage of the region.
