The Lusitanian Basin records the syn- to post rift evolution of the West Iberian Margin showing some outstanding examples of the combined tectono-stratigraphic depositional systems. Here, the Upper Jurassic reveals diverse aspects of mixed depositional systems including submarine fans, the build-up of carbonate reefs and shoreface to fluvial sequences. Throughout the fieldtrip the different depositional aspects can be observed to demonstrate how such depositional systems can vary in time and space.

The objective of the field trip is to gain or increase an understanding of the tectono-sedimentary processes of continental extension and rifting supported by outcrop observations, with focus on turbidite depositional systems. Promote debate and nourish new insights between attendants.

We will start at the eastern limit of the Lusitanian Basin where coarse-grained submarine fans deposited from a nearby sediment source area and move towards the central part of the Basin westwards. Dramatic lateral facies variations due to the active rift tectonics will be observed, from reefs at the top of rift shoulders to deep marine shales and marls, cut by sandy turbidite channels.
