500m high cliff in the Early to Middle Pleistocene Evrostini Gilbert-type fan delta, Corinth Rift
The Gulf of Corinth is one of the fastest opening rifts in the world with a rate of NS extension of up to 1.6cm/yr. On the south side of the Gulf, the rift’s tilted fault blocks and their synrift succession (Late Pliocene-Middle Pleistocene) are exceptionally well exposed due to rapid uplift up to 1200m. and deep incision by rivers. The clastic rift succession, up to 2.8 km thick, includes a series of spectacular giant Gilbert-type fan deltas (up to 800 m. thick, radii up to 4km) that are used as analogs for reservoirs in the North Sea and elsewhere. These are exposed on cliffs up to 800m. high where their stratigraphic architecture and facies can be studied in detail.
The aims of this trip are to present and discuss (a) the rift’s stratigraphy and structure, (b) the geometry and kinematics of the normal fault network and (c) the stratigraphic architecture and facies of selected Gilberttype fan deltas. These observations will be used to debate topics such as sequence stratigraphic interpretations and modeling of fan deltas in active rifts, the controlling factors in delta construction and distribution, geometry and connectivity of a normal fault network, the interaction of surface processes (sediment flux, climate) and tectonics in active rifts.
