Laga Formation: large scale geometry of a channelized sandstone body
Marnoso-arenacea Formation: geometry of structurally-confined strata

Turbidite deposits developed in structurally confined basins show depositional elements as channels, lobes, and basin plains featuring highly variable facies, complex geometries and characteristic hierarchies, which can be analyzed only through a detailed examination of outcrops and the measure of several stratigraphic -sedimentological sections. To this purpose exceptionally good exposures are required.
The Miocene foredeep turbidite deposits of the Marnoso-arenacea and Laga Formations satisfy this condition and provide a large amount of quantitative information.
In this field trip we will discuss about the origin, provenance and evolution of the flows related to these turbidite successions as well as the main facies and physical stratigraphic features.
At the same time we will also discuss about the relationships between tectonic and sedimentation of these basins in the context of the northern and Central Apennines Miocene foreland basin system.

Itinerary

Rome, Firenzuola, Castel del Rio, Mercato Saraceno, Sarsina, Bagno di Romagna (day 1, day 2 and part of day 3 ); Rocca Fluvione, Acquasanta Terme, Mt. Bilanciere, Poggiumbricchio, Rome (part of the day 3, day 4 and day 5)

Technical Information

The participants will be carried with two or three minivans. The excursion take places at relatively low altitude (100-1200 m); in September the weather is relatively stable (15°-28°), although change with rain are possible. Most of the outcrops are along the road and we will not make long walks. Trekking boots, sun-protection and hats or headscarves are recommend as well as a sweater, a wind jacket, a foldable umbrella, a bottle of water and a backpack.
