Palaeocurrent directions as an indicator of Pindos foreland evolution (central and southern part), Western Greece

Abstract

In order to estimate the palaeoflow direction of the submarine fans, deposited in the Internal Ionian subbasin of the Pindos Foreland, fifty-one positions along the sub-basin were selected and measurements of palaeocurrents indicators such as flute and groove marks were taken. In the studied area the main palaeoflow direction of turbidites was axial, from south to north in the southern part, and from north to south in the northern part. A minor westward palaeoflow direction is also present. These palaeoflow directions were influenced mainly by the regional tectonic activity, such as internal thrusting (Gavrovo Thrust) and differential activity of the Pindos Thrust which subdivided Pindos foreland into narrow linear sub-basins.

Sedimentary Characteristics and Basin Evolution of a Compartmentalized Foreland Basin—Internal Ionian Zone, Western Greece

“…These lithological types were then grouped into discrete facies that were used as a key to recognize facies associations that corresponded to genetic elements of submarine fan deposits. Paleoflow patterns of submarine fans and dating data from previous research in the area [51,52] completed the available data set for the analysis, providing the information to identify facies associations and their distribution and potential reservoir units.…”

“…Pindos foreland was affected by the presence of internal thrusting and transfer faults, causing changes in depth and width. Due to internal thrusting (Gavrovo, internal and middle Ionian thrusts), creating intrabasinal highs that influenced palaeocurrent directions (Avramidis and Zelilidis, 2001;Konstantopoulos et al, 2013). Transfer faults cross-cut the intrabasinal highs and produced low relief areas that act as pathways for sediment distribution.…”

Age Determination and Palaeogeographic Reconstruction of Diapondia Islands in Nw Greece, Based on Calcareous Nannofossils

“…The studied area (North-western Greece) is a part of the external Ionian zone. Clastic sedimentation in the Ionian zone took place from middle Eocene to late Miocene in a foreland basin, the Pindos foreland (Avramidis et al, 2002;Vakalas et al, 2001) which was subdivided due to internal thrusting and changed to a complex type foreland basin. It belongs to the external Ionian zone and thus to the western part of the Pindos foreland, bounded eastwards by the middle Ionian internal thrust and westwards by the Ionian thrust.…”

“…The presence of strike-slip faults, with ENE-WSW direction, internal to the foreland basin, influenced the depositional conditions in the studied area. Internal thrust activity together with the sedimentation, has influenced transportation and grain-size distribution, whereas strike-slip faults many times acting as pathways to deliver coarse-grained sediments in more distal parts (Avramidis & Zelilidis, 2002;Vakalas et al, 2001). Many times the continuous uplift due to internal thrusting produced large slumps horizons of the uncondensed sediments, deposited over the uplifted area (Avramidis et al, 2002).…”
