On The Foreland Monoclines and Foredeeps in the Mediterranean Belts
Authors C. Doglioni and G. MariottiThe foreland monocline is a common feature for all thrust belts or accretionary wedges and related foredeep (Bally, 1983). The foreland geology is often understated in regional studies of orogens, in spite of its crucial role in controlling the thrust belts evolution. The foreland monocline tends to increase its dip toward the interior of the belts (Boyer, 1995), and its subsidence rate controls the development of the trench or the foreland basin, whatever is their origin.

Structual Model of Central Eastern Sicily
Authors M. Bello and S. MerliniSeismic surveys in Central-Eastern Sicily are located mostly where hydrocarbon exploration is concentrated, namely Hyblean area to the South and the Nebrodi range to the North (Fig 1). The recent acquisition of three regional seismic profiles in the central Sicily created a link between these two areas. This has supplied a lot of informations on the structural setting of this part of the Sicilian thrust belt, in comhination with well log, surface stratigraphic and structural data, magnetometric and gravirnetric data and allowed us to define a new geo-structural model for this area.

Crustal Structures from the Eastern Algerian Basin to the Ionian Ocean - Central Mediterranean
Authors R. Catalano, A. Franchino, S. Merlini and A. SulliResults from the interpretation of deep seismic lines (CROP Italian Deep Crust Project) provide the first, continuous, 900-km-long crustal geologic transect crossing the Central Mediterranean from the Algerian Sea to the lonian Sea (Fig. 1). The geoseismic section (Fig. 2) reveals crustal and Moho reflections to a depth of about 30 km and elucidates the crustal architecture and processes associated with the opening of the Oligo-Miocene Algerian-Provencal basin, the Tertiary mountain building of the Alpidic chain and the Mesozoic continental rifting to oceanic spreading of Malta-Iblean margin-lonian abyssal plain.

Petroleum Exploration Strategies in Mobile Belts
Authors F. Roure, D. G. Howell and R. SwennenForeland fold-and-thrust belts (FFTB) still comprise the World's largest petroleum reserves. However, due to their structural complexity, FFTB frequently constitute a frontier for the exploration. Based on the distribution of surficial seepages, first drillings were focused on shallow targets, either in shallow anticlines near the thrust front, or in dominantly stratigraphic traps, up-dope the regional foreland flexure.

Computer Modelling of Petroleum Systems Along Regional Cross-Sections in Foreland and Fold-and-Thrustbelts
Authors W. Sassi and J. L. RudkiewiczThis paper describes a methodology to evaluate a petroleum system in fold-and-thrustbelts. This methodology is based on the reconstruction of the structural evolution on a regional cross-section and on the modelling of the thermal regime at present time and through geological time. The onset of hydrocarbon generation and expulsion from source rocks into traps, resulting from the temperature history and the kinetics of the kerogens can be investigated. The modelling accounts for the changes in the composition of hydrocarbons during generation and expulsion from the source rocks and may be instrumental to predict the global composition of trapped hydrocarbons in developing structures. This methodology was applied to many history cases from well known petroleum provinces of fold and thrustbelts environments. In many case, initial geologic interpretations can significantly be improved by reconstructing the past thermal regimes and maturity evolution computed from the result of a geometric and kinematic forward evolution on a regional cross-section.

Surface Controls on the Thermal Regime of External Zones of Orogenic Belts
Authors L. Husson and I. MorettiIn extensional settings, the thermal evolution is closely linked to the global geodynamic development (lithospheric and crustal thinning). In collision areas, numerous processes acting on the thermal field. are superimposed and the evolution through time is subsequently more complex. The surface heat flow density (HFD) distribution across active orogenic belts show large variations and illustrates that no standard profile can be proposed (fig .1).

A New Technique for 3D Restoration of Flexural Slip Folds
Authors P. A. Griffiths, N. Saltar, F. Schaefer, S. Jones and H. ReiserA new structural restoration and forward modelling flexural slip technique for three-dimensional (3D) digital models has been developed. The flexural slip method preserves volume in 3D, line length (of the template surface and layers parallel to this surface) in a given unfolding direction and orthogonal bed thickness. The model surfaces need not be parallel to each other. These constraints allow 3D fault-propagation, fault-bend and detachment folds to be restored or forward modelled.

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.

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.

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.

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.

Enhancing Structural Analysis with the Fourier Transform - An Example from the Berkine Basin, Algeria
Authors W. I. Taylor and F. J. GauthierThe primary challenge of structural geologists in the petroleum industry is to characterize the spatial distribution of folds, faults, and joints in the subsurface and to understand how these features effect the migration and entrapment of hydrocarbons. In most cases, subsurface data are insufficient to accurately characterize rock deformation at the desired scale. As a result, conceptual models are invoked to help translate sparse data sets into structural interpretations. The selection of an appropriate model is often lelt to intuition or is based on a "common perception" that has not been verified.

Habitat and Exploration Potential of the Ultra-Deepwater Offshore Mediterranean
Authors A. Abdel Aal, A. El Barkooky, M. Gerrits, H. Mayer, M. Schwander and H. ZakiThe Northeast Mediterranean Deepwater Block lies in water depths of 800m to 2800m in front of the Nile Delta Cone. The Block is exceptional for its site (41,500 km2), roughly equal to the total area presently licensed over the Nile Delta, which to date has yielded dry gas and gas/condensate. The structural and stratigraphic setting of the block offers a variety of hydrocarbon trapping possibilities similar to the deegwater settings of other productive deltas. This venture falls in the category of real frontier exploration opportunity.

Depositional Model of the El Garia Formation, Lower Eocene - The Example of the Kef El Guitoune, Central Tunisia
Authors C-A. Hasler, E. Davaud and R. BoichardThe lower Eocene Metlaoui Group contains proven economic petroleum reserves onshore and offshore Tunisia and Libya and is still an exploration target (e.g. Bishóp, 1988). Since the Ypresian deposits located in Tunisia crop out in very good conditions and are well documented (see e.g. Moody and Grant, 1989, Loucks et al., 1998), they constitute a very good example of a carbonate ramp model applicable to a hydrocarbon field.

Authors Y. A. Al Fasatwi, P. M. van Dijk and A. A. MissilatiThe mapping of the arch structures of Libya, which separate most Libyan sedimentary basins from each other, can significantly enhance the understanding and modeling of their tectonic formation and deformation history. These arches were effective in localizing truncation, unconformities and onlap of depositional sequences. In addition, they are likely to be focal points for oil migration and accumulation.

Hydrocarbon Potential of Mediterranean Region
By H. RempelMediterranean region comprises the littoral states of the Mediterranean Sea. Seen in a global framework, the hydrocarbon reserves and production of these countries are relevant. Their combined share of world production lies between 5 and 6%, of the world reserves at about 4%, resources between 2 and 4%, consumption is higher (see fig. 1).

Hydrocarbon Seeps in Al Qarqaf Arch, NW Libya, Spatial Distribution and Geochemical Analysis
Authors Y. A. Al Fasatwi, M. S. Hrouda and M. M. ElkelaniResidual petroliferous materials are often indications that hydrocarbons have at some times passed through particular rock types, formations or structures. The study of the nature of hydrocarbon seeps can help to provide a better understanding of the hydrocarbon trapping potential of an area.

Libya - A New Depth-To-Basement Interpretation from Potential Fields Data Constrained by Well Data
Authors S. Z. Jassim, S. J. Campbell and I. W. SomertonOil exploration companies have collected gravity and magnetic data in Libya for over 50 years. In fact, potential field methods were among the original geophysical techniques used to map and delineate oil-bearing structures in Libya prior to the introduction of the seismic reflection method. They still remain cost effective methods, but now tend to be used in support of the seismic method.

Depositional Conditions of Mid-Eocene Nummulite Accumulations in the Gulf of Gabes, Tunisia
Authors M. K. Hauptman, J. Bartholdy and R. BischoffNummulitic limestones in the Gulf of Gabes and onshore Central Tunisia i.e. the Early Eocene (Ypresian) El Garia Formation and the Mid-Eocene Reineche Member are generally interpreted as hydrodynamic storm-derived nummulite accumulations. Such models try to explain the characteristic irregular bedding and scattering of nummulites by the occurrence of chaotic turbulent current patterns during storm events.

High Resolution Sr Isotope Stratigraphy in the Turonian-Maastrichtian Carbonates of the Periadriatic Domain
Authors R. Cestari and M. OrlandoThis poster shows briefly how in ENI Agip Division the Strontium Isotope Stratigraphy (SIS) is being applied as a stratigraphic tool. SIS is considered in addition to the classical paleontological analyses for dating purposes, when sedimentary rocks have no diagnostic fossil or when fossil assemblages are affected by bio-provincialism problems, and/or when a marked dependency on the facies/depositional mechanisms is observed.
