Permo-Triassic Evaporites of Southeastern Europe-a new context for hydrocarbon prospectivty
By D. TufekcicPermo-Triassic evaporites in southeastern Europe are usually treated as a neglected child of regional geology. Sometimes they are only briefly mentioned as a possible decollement of the complex tectonics of this area, but rarely as a basinal product worth of primary interest as a distinctive petroleum system. With the advent of a new seismic processing techniques, the key regional lines were recently reprocessed using the wave equation layer replacement method. Not only were seismic images significantly improved, but a new model of the Permo-Triassic evaporite deposition was also defined, pointing to a basin-central evaporite model type of deposition. A regional geophysical analysis of the central and northeastern part of the Adriatic Basin has been integrated with an evaluation of the seismo-stratigraphy of the Permo-Triassic evaporites to provide a geological framework for the basin setting definition. In addition, this study recognizes that the marginal evaporitic units record Permo-Triassic salt tectonics which is characterized by reverse faults associated with the regional salt ridges. This new tectonic model proposed here for the northeastern edges of the Permo-Triassic evaporites of the Adriatic Basin, as an alternative to thrust faults previously suggested, has important implications for hydrocarbon migration and trapping. The study suggestes that the salt repositining and tectonic evolution of the salt basin margin during the Tertiary have the key implications for hydrocarbon prospectivity. At this stage of study the size of the northwestern part of the Permo-Triassic Basin extends across 300x600 km. However, if the circum-Ionian region (Albania and Greece) is included, the size of the basin could be easily twice as large. For the future petroleum exploration of such an enormous and complex basin the prime issue will be the application of innovative seismic tools and further refinement of evaporite stratigraphy.

The River Terraces - Indicators of the Neotectonic Movements in Albania
Authors R. Koçi, S. Bushati, J-L. Mugnier and E. PerenjasiFrom the geological point of view, the whole Albanides thrust belts, represent an integral part of the Dinarides-Albanides-Hellenides arc in the framework of the Alpine folding cycle. Albanides situate along the eastern banks of the Adriatic and Ionian seas, between Dinarides in the north and Hellenides in the south, and overthrust onto the Adria microplate. In other words, the arc of Dinarides-Albanides-Hellenides and the Adria microplate move in the opposite directions across their convergent tectonic boundary. The movement of the Adria microplate is among the main data of reading the deformation phenomenon and tectonic stresses generation along the western margin of the Dinarides-Albanides-Hellenides arc and in the whole central Mediterranean [Altiner, Y et al., 2006]. Also, the Apennines belts overthrust eastward onto the Adria microplate. Consequently, the organic movements of the thrust belts towards the Adria microplate have brought about formation of the western asymmetry thrusted structures and few tectonic napes across the Albanides thrust belts [Aliaj et al., 1996] (fig 1). In other words the pressure stresses regime of the convergence in question have generated a complicated tectonic setting of the Albnides in general, and of the external Albanides and pre-Adriatic Depression in particular [Jouanne et al., 2007]. Subsequently, the whole Albanides have an active neo-tectonic regime, expressed through frequent seismic shakes, hard relief, and steep slopes of the river valleys and existence of several levels of terraces formed during Plio-Quaternary to present days (fig 2).

Use of 2-D resistivity images in search for buried objects at the Rrogozhina archaeological site (Via Egnatia)
Authors S. Kasapi, S. Nenaj, H. Reçi and G.N. TsokasGeophysical technique of 2-D electrical imaging has been used to explore the archaeological features along a part of ancient ViaEgnatia road. With the use of geoelectrical survey, a 200x160m area has been explored using detailed 2-D resistivity measurements. Two tomogaphic profiles 100m long were carried out in order to detect parts of ancient road axis. The main objective of the project was the exploration of buried archeological features and the possibility of existence of any segment of ViaEgnatia Road. This work has been carried out in cooperation with Institute of Archaeology of Albania, which determined the area to be surveyed. The methodology used, consisted in resistivity mapping using the Electrical Resistance Tomography (ERT) technique, thus obtaining resistivity contour maps at different depths. Geoelectrical data has been collected by staff of Geophysical Center of Tirana, Albania during the year 2005. Geophysical Department of Aristotle University of Thessaloniki, Greece, gave the appropriate help in data interpretation.

Using the seismic methods for contouring the existing oil field in Albania
Authors I. Gjermani, V. Ngresi and K. JanoThe carbonate oil field in Albania are located in Ionian tectonic zone of the external Albanite and on the west side of the country. This article deliver the interpretation of the geology-geophysical on line oilfield anticline structures as well prospected structures for the future exploration such as Selenica-Gorisht-Kucul, Amonica, Amanitia-Ramica, Cakran-Mollaj, Ballsh - Hekal and Visoka, Patos-Verbas The structures where is founded oil in them in Albania are in the northern part of the Kurveleshi Belt. (Fig. 1). From the tectonic point of view the Kurveleshi Belt is the center part of Jonian tectonic zone and characterize with very tectonic active and there are generics and store deposits in the carbonates of Mesozoic. Reprocessing the seismic data, by using the update programmers and the correct layers velocity in the area where backthrust and overthrust are present, has help to much in interpretation the geological model and have certificated the new prospect structure for oil.

Geophysical Investigation of Hydrogeological Conditions and Salination Processes at the Marathon - Kao Souli Basin (NE Attica, Greece)
Authors G. Sideris, P. Sotiropoulos, A. Tzanis, S. Chailas, C. Kranis and P. KarmisThis work presents the results of gravity, TEM and geological surveys conducted in the area of Marathon - Kato Souli Plain, as part of an effort to study its hydrogeological characteristics. The gravity survey offered a rather detailed image of the alpine basement and together with surface geological observations, insight into the post-alpine tectonic processes that have controlled the development of the area. The TEM survey produced detailed three-dimensional images of the aquifer systems and salination conditions. The results have shown that (a) the alpine basement is located much deeper than previously thought and, (b) that the sea water intrusion takes place both near sea level and at depth. The depth and morphology of the alpine basement are believed to have been fashioned by faults that either have not been active during the Quaternary, or are buried under thick terrestrial and alluvial deposits. Sea water intrusion forms at least two distinct salination horizons, presumably as a result of intersecting faulting structures that facilitate horizontal and vertical transportation of sea water between permeable formations. The vertical alternation of permeable-impermeable rock formations may be attributed to (alpine) folding, which results in vertical repetition of the same lithological units, in this case karstified marbles.
