Due to the good exposures and the already available, detailed stratigraphic and geological data, the Marnoso-arenacea Formation (MA) represents a unique opportunity for the study of the overall geometry and internal organization of slide bodies and related sedimentary structures. Submarine slides are common within the MA and involve sediments of various origin and degrees of consolidation. Slides are sandwiched between both deep-sea plain sediments and slope deposits. Attention is focused here on the large-scale bodies cropping out in the Romagna sector of the Marnoso-arenacea basin, between the Sillaro and the Marecchia valleys. They crop out extensively and represent unique opportunity to see how the internal structures of flow developed during the traslation and emplacement of the mass-transport bodies, in response to slope/basin morphology and the interaction with the substratum.
