Semi-Automatic Detection of Subsurface Seismic Bodies of Relevant Stratigraphic Interest
Authors L. Ferri, M. Fervari, M. T. Galli and P. RocchiniExtensive 3D seismic volumes from around the world have started to show geometry and facies textures of geobodies, which traditionally interpreted through conventional 2D vertical sections, following a time-consuming seismic stratigraphic approach. This method is too labor-intensive and error-prove to be cost-effective.

Widespread Lgm Axial Incision in Submarine Canyons of the Western Gulf of Lions
Authors J. Baztán, S. Berné, M. Canals, J-L. Olivet, M. Rabineau, J-P. Rénault and J. LofiA detailed morphological analysis of the submarine canyons in the Western Gulf of Lions shows the widespread occurrence of an axial incision excavated within the main valley. Such an incision is interpreted as a relict feature dating from the Last Glacial Maximum when sediment transfer from river mouths to canyon heads was enhanced due to sea level lowstand and to increased continental runoff.

High-Frequency Sea-Level Changes Control the Recent Sedimentary Architecture of a Small Modern Turbidite System
Authors F. Pérez-Belzuz, B. Alonso and A. GalimontThe morphology, sedimentary architecture and recent sedimentary evolution of the Calahonda Turbidite System (Alboran Sea, SW Mediterranean) was established through the analysis of ultra-high resolution seismic profiles, swath bathymetry and sediment cores.

Control of Thrust Propagation on Turbidite Sedimentation
Authors A. Artoni, D. Di Biase, E. Mutti and R. TinterriIn foreland basins, the deep and narrow trough which forms adjacent to the thrust front is commonly termed foredeep, and, until the orogenic wedge is not significantly uplifted and emerged, the trough is characteristically filled in with axial turbidites sourced from fluvio-deltaic systems located in emerged areas of adjacent orogens where substantial tectonic uplift has already occurred.

Deep-Water Canyons in Circum-Mediterranean Regions - From Erosional Vacuities to Entrenched Meanders
Authors B. T. Cronin and A. HurstThe origin and morphology of deep-water canyons bas been the subject of many oceanographic expeditions since the late 1960s. Their recognition at outcrop has been inferred in many turbidite basins on the basis of evidence for prolonged periods of sediment bypass, usually during tectonically driven periods of basin margin reconfiguration, or the presence of attenuated packages of clast-supported gravels in association with deep-water shales.

Facies and Processes of Turbidite Systems
Authors E. Mutti and R. TinterriOver the past two decades marine geological investigations, outcrop studies, laboratory experiments and numerical modelling, and, particularly, a wealth of seismic, well-log and core data derived from extensive exploration for hydrocarbons carried out in many offshore basins worldwide, have provided an increasing body of evidente indicating the very complex and stip poorly understood nature of many deep-water sandstone facies.

Tectonics of the Eastern Mediterranean
Authors X. Lepichon, C. Rangin and N. Chamot-RookeThere has been a considerable amount of studies of the lands bordering the Eastern Mediterranean basin but the basin itself is still relatively poorly known. The tectonic analysis of this basin is difficult to do because a great part of it has disappeared within a double system of subduction zones, the Hellenic one that is stip active and the Calabrian one that stopped being active less than one million years ago.

New Insights on the Mechanisms of Deformation on the Eastern Mediterranean Ridge
Authors A. Camerlenghi, E. Costa, A. Polonia, C. Cooper, P. Fabretti, A. Moscini, P. Murelli, M. Romanelli, L. Sormani and N. WardellShortening along the Mediterranean Ridge is the result of convergente between Africa and Eurasia plates and the motion of the Aegean microplate.

Deformational Styles of the Central and Eastern Mediterranean Ridge
Authors J. Mascle, C. Huguan, J. Benkhelil, A. Volkonskaia, J. Woodside and theScientific PartyDetails of the sea floor and of deformational styles of large portions of the central and eastern Mediterranean Ridge (MR) are revealed in recent 100% coverage swath bathymetry, acoustic imagery, together with continuons seismic profiling.The MR is a wide accretionnary wedge that results from convergente and ongoing incipient collision between Europe, Africa and the Anatolia-Aegea microplate, in Eastern Mediterranean.

General Tectonic Framework of the Eastern Mediterranean
More LessOur understanding of the tectonic framework of the eastern Mediterranean has greatly improved in the past ten years or so. New research has benefited from deep sea drilling by the Ocean Drilling Program (ODP), the extensive use of new techniques such as multibeam swath mapping, unexpected results from investigations of mud volcanoes and fluid seeps, and exploration of areas of potential resources like the Nile offshore.

First Results from the Multi-Channel Seismic Reflection Study in the Gulf of Marmaris
Authors N. Ocakoglu, E. Demirbag, B. Ecevitogli, I. Kuscu, C. Gocmen and S. KaragozThe active tectonism in the Gulf of Marmaris located at the southwest Anatolia Renion was investigated by means of multi-channel seismic reflection data.

Exploration in NW Greece with Application of Passive Seismic Tomography
Authors K. Eleni, T. G-Akis and M. AlbertoTomographic Passive Seismic Inversion utilising P and S-wave travel times from 455 local micro-earthquakes has been applied in Epirus (NW Greece). The objective of the project was to image the sub-surface volume in the region, an area which is currently being explored for hydrocarbons by a consortium operated by Enterprise Oil.

A New Sub-Thrust Play for Hydrocarbon Exploration in Central Albania - Seismic and Structural Interpretation
Authors E. Deville and A. CollakuThe stratigraphy of the Ionian and Kruja Albanian zones can be subdivided in four sedimentary sequences: 1. Triassic evaporites, 2. lonian Triassic to Eocene basin and Kruja platform carbonates, 3. Oligocene to Burdigalian flysch, and 4. Tortonian to Pliocene molassic sediments deposited in the foreland basin.

Neotectonic Features Revealed by Seismic Data on Periadriatic Depression, Albania
By J. SkramiThe Preadriatic Depression is located in the western part of Albania. The Preadriatic basin is formed after the main folding and .thrusting of Ionian zone and is filled with Mio-Pliocene molasse. The folding and thrusting of Preadriatic Depression is finally due to the Early Pleistocene compressional phase that is evidenced by some important structural unconformities. The Preadriatic Depression is built by some linear relatively narrow anticlines, superimposed over thrust or backthrust faults, and wide synclines.

Continental, Sabkha and Shallow Open Marine Liassic-Triassic Sequence Offers New Exploration Plays in Malta
Authors G. Debono, S. Xerri and W. F. BishopEarly Jurassic and Triassic sedimentary rocks from a deep well on the island of Gozo, Malta, show a remarkable correlation with contemporaneous ones in North Africa The prevailing depositional environment during the Middle to earliest Late Triassic in the Gozo area was transitional with deposition of anhydrite and shales equivalent to the evaporitic facies of the Currusc Formation of North Africa.

Norian Carbonate Platform and Related Basins - An Example from the East Lombardy Southern Alps, Italy
Authors P. Ronchi, R. Fantoni, P. Scotti, G. L. Trombetta and D. MasettiThe Upper Triassic succession of the Lombardy Basin includes petroleum systems composed of carbonate platform reservoirs and intraplatform basin source rocks. These systems are proved to be efficient in the subsurface oil fields of the Po Valley.
