Geological construction of southern part of Ionian zone based on interpretation of seismic data

Abstract

The Ionian zone is the main object of seismic interpretation for a long time. Within this framework, we shall analyze the new seismic intrpretation methods used in oil and gas exploration in the western part of Ionian zone. The Ionian zone is very complex involving certain tectonic faults. In the central part, we can see the duplex tectonic style. Anticline belts from east to west can be interpreted.The Ionian zone comprises three anticline belts:Berati belt, Kurveleshi belt and Cika belt. By application of SeisWork2D in the eastern part of the belt, we have evidenced some perscpective structures, meanwhile in the western part, the seismic quality is very chaotic. Kurveleshi belt is constructed by structures of various forms and dimensions associated with developed tectonics up to thrusting. Cika anticline belt is constructed mainly by prolonged structures of considerable dimensions associated with evaporate outcrops as in Xara, Fterra, Cika etc.

Contrasting Styles of Salt‐Tectonic Processes in the Ionian Zone (Greece and Albania): Integrating Surface Geology, Subsurface Data, and Experimental Models

“…The names given in Greece and Albania to these thrust sheets vary, but we propose the following correlation from innermost (east and shallower) to outermost (west and deeper): Berati or Internal Ionian, Kurveleshi or Middle Ionian, and Ҫika or External Ionian (BP, 1971; IFP, 1966; Karakitsios & Rigakis, 2007; Mazzoli et al., 2022; Papanikolaou, 2021; Velaj, 2015b; Zelilidis et al., 2003, 2015). In Albania, another thrust sheet, the Sqepuri thrust sheet (Figure 8a), has been locally differentiated (Bare et al., 2001; Meço et al., 2000; Roure et al., 2004; Sadekaj et al., 1992; Sejdini et al., 1994; Velaj, 2001; Velaj et al., 1999; Xhomo et al., 2002). Due to its position and deep structure, we interpret the Sqepuri as an imbricate of the Kurveleshi (Middle Ionian) sheet.…”

Contrasting Styles of Salt-Tectonic Processes in the Ionian Zone (NW Greece and S Albania)

“…Our interpretation of the general structure of the IZ is given in the two regional cross sections in Figure 8 (Institut_Francais_du_Pétrole_Mission_Grèce, 1966;Karakitsios & Rigakis, 2007;Papanikolaou, 2021;The_B.P._Co_Ltd., 1971;Zelilidis et al, 2015;Zelilidis et al, 2003). In Albania, another thrust sheet, the Sqepuri thrust sheet (Figure 8a), has been locally differentiated (Bare et al, 2001;Meço et al, 2000;Roure et al, 2004;Sadekaj et al, 1992;Sejdini et al, 1994;Velaj, 2001;Velaj et al, 1999;Xhomo et al, 2002). Due to its position and deep structure, we interpret the Sqepuri as an imbricate of the Kurveleshi (middle Ionian) sheet.…”
