The fortress of Phyle is mentioned in several ancient sources. Xenophon holds that it was captured by Thracyboulos in 404 B.C. when he set off against the 30 tyrants (Xenophon Hellenica II, 4, 2-7). Archaeological evidence, however, points towards a later dating of the fortress in the first quarter of the 4th century B.C. It was constructed as part...

Significant evolutionary stages of Selinitsa Cave (SW Peloponnese, Greece) were revealed by 3D mapping, as well as geomorphological study of the cave and the nearby landscape. Four marine terraces were identified in the area of the coastal cave at 6, 10.7, 16.6, and 30–32 m above sea level (asl), with the terrace at 16.6 m representing Marine Isoto...

A combination of well data, seismic information on thrusting and tectonic shortening, plus analyses of the nature and depth of the Mesozoic units related to main detachment horizons (Triassic evaporites, flysch), are used to review and further update the complex structural styles of the External Hellenides and Albanides Orogenic Belts, SE Europe. I...

Seismic reflection data and bathymetry analyses, together with geological information, are combined in the present work to identify seabed structural deformation and crustal structure in the Western Mediterranean Ridge (the backstop and the South Matapan Trench). As a first step, we apply bathymetric data and state of art methods of pattern recogni...

Thrust faulting plays an important role in the structural deformation of Gavrovo and Ionian zones in the central part of the ‘External Hellenides’ fold-and-thrust belt. The Skolis mountain in NW Peloponnese as well as the Varassova and Klokova mountains in Etoloakarnania are representative cases of ramp anticlines associated with the Gavrovo thrust...

Giouchta Mt. is located south of Heraklion city, in Crete. It is an N-S trending morphological asymmetric ridge, with steep western slope whilst the eastern slope represents a smoother relief, composed of Mesozoic limestone and Eocene- lower Oligocene flysch sediments of the Gavrovo -Tripolis zone. The present study focuses on the geological struct...

The Giouchtas Mountain is situated south of Heraklion, Central Crete. It is a N–S trending morphological asymmetric ridge with a steep western slope, whilst its eastern slope is characterized by a smoother relief, composed of Mesozoic limestone and Eocene–lower Oligocene flysch of the Gavrovo–Tripolis zone. The present study focusses on the structu...

In the context of the present study the structural pattern in the Western Thessaly Basin (Greece) has been examined, based on structural data collected from the entire study area that were further correlated to the hydrographic network. The structural pattern of the area was revealed from tectonic analysis. Additionally, the topography, stratigraph...

A multidisciplinary approach is used to investigate the structure of the southern Cretan margin, which is located in one of the most seismically active forearc regions in Europe. Bathymetric, seismic-reflection, and fault plane solution data were used to identify the main tectonic features on the margin, correlating their evolution with the main se...

A multidisciplinary approach is used to in-vestigate the structure of the southern Cretan margin, which is located in one of the most seismically active forearc regions in Europe. Bathymetric, seismic-refl ection, and fault plane solution data were used to identify the main tectonic features on the margin, cor-relating their evolution with the main...

The structural style of the fold-and-thrust belt in the western part of the Hellenic foreland in an area offshore the Zakynthos Island is assessed on the basis of two lithoseismic profiles, earthquake data and field data in the broader area. The compressional deformation in the area is due to the late phases of subduction and collision between Aege...

The marine fill of the Gavrovo-Tripolis foreland basin in the Messinia area (SW Peloponnese), includes facies and facies associations, deposited by sediment gravity flows in slope and inner fan settings. The above-mentioned gravity-driven sedimentary processes, resulted in the formation of thinning-upward sequences and fining fan facies association...

The structural deformation of Mesozoic-Tertiary sediments of the Ionian and Gavrovo zones in NW Peloponnesos is related to the propagation of a fold-thrust system during the Cenozoic. The sediments of the Gavrovo zone have been deformed by high angle reverse faulting generating an imbricate fan. Skolis mountain represents the Gavrovo thrust front....

The Kythira–Antikythira strait, within the SW Hellenic Arc, forms a 100 km long NNW–SSE trending ridge between Peloponnesus and Crete and represents the submarine continuation of the Hellenic Alpine belt. In order to present the shallow as well as the deeper structure of Kythira–Antikythira strait we studied five seismic sections, oriented either p...

Based on calcareous nannofossils and planktonic foraminifera biostratigraphic data from flysch sequences, we give evidence for the paleoenvironmental evolution of Gavrovo and Ionian foreland basins (External Hellenides, Etolakarnania region). Our data suggest that the onset of clastic sedimentation in both foreland basins in the study area is chron...

Multiple attenuation comprises a very important phase of seismic reflection processing because it removes undesirable effects occurring during propagation of seismic signal in the Earth. The present work aims to present the effectiveness of modern multiple suppression methods applied on streamer seismic reflection data. The seismic dataset represen...

Information concerning two seismic lines, the first located northwest of the Lefkada Island and the second from the deep Ionian basin to the gulf of Patras, is used to trace the Kefalonia Transform Zone (KTZ) and to explore its relation with the sedimentary sequences and the deeper geologic structures in the study area. In addition, sea bottom topo...

The NW Peloponnese (Greece) belongs to the west-verging Alpine thrust-fault belt. Deep-water sedimentation ensued, in the Gavrovo-Tripolitza and Ionian foreland basins, as relief was being built-up and the Tertiary compression migrated westwards. The deep-water sedimentation and the deep structure of the thrust-fault belt are hereby assessed on the...

Contractional structures recognised in a recent SW‐NE oriented seismic profile offshore western Greece, between the islands of Zakynthos and Kefallinia (Cephalonia), indicate that this part of the Pre‐Apulian geotectonic zone was involved in Quaternary shortening related to the westward propagation of the Hellenic fold‐and‐thrust system. Deep refle...

Samples of the Ionian zone (western Greece) subsurface evaporites, obtained from well cores in salt bodies and in depths ranging from 1000 to 3500m, are texturally studied. Layered halite rocks consisting of chevron-type halite crystals represent most of the specimens. Between the chevron –type halite crystals, which are fluid inclusions-rich, clea...

The model of a foreland propagating sequence already presented for the External Hellenides is significantly modified in this paper. New data are used, including structural maps, cross-sections, stratigraphic determinations and seismic profiles. In general, thrusts formed a foreland propagating sequence but they acted simultaneously for a long perio...

In the sedimentary basins of Greece are found a lot of hydrocarbon gases that can be distinguished in four categories. Surface gas seeps, gas shows in shallow water-wells, gases in exploration wells and hydrocarbon gas fields. The main gas shows are mainly located inside recent clastic sediments. Hydrocarbon amount varies between a few ppm and seve...
