“…In general, the upper Cretaceous Senonian limestones are characterized by microbreccia, calciturbidites and slumps, as recognized in other areas (Bourli et al, 2019a). In total, microfacies analysis from all the studied sections, showed in general a deep-sea environment of sedimentation, with a few exceptions that indicate a shallower environment character, introducing the possibility for the existence of platforms, close to the studied sections.…”

“…This axially basin changes could be related with along the basin restrictions, which could be related with the synsedimentary transfer fault activity. The synchronous activity of transfer faults with the major normal faults produced during the sedimentation phase paleo valleys where the Vigla shales were accumulated (compare the proposed model of Bourli et al, 2019a).…”

“…These deposits are mostly composed of calciturbidites interbedded with breccia-microbreccia deposits. According to Bourli et al, (2019a) the studied outcrops from Araxos area (internal Ionian sub-basin) showed that the breccia -microbreccia deposits are structureless, with a channelized geometry and calciturbiditic blocks internally to the channels; whereas most of the clasts were sourced from the underlying Lower Cretaceous "Vigla limestones". Moreover, microfacies analyses indicate deep-water deposits and reworked shelf deposits.…”

Sedimentological studies of the Cretaceous limestones in the central Ionian basin (Amfilochia, Arta as well as Kerasonas areas) indicate that these deposits are composed of calciturbidites interbedded with breccia-microbreccia deposits. In the Amfilochia new cross-section, with a NNW-SSE direction, the lower Cretaceous Vigla limestones and Vigla shales were outcropped for the first time. This section is directed parallel to the paleo Ionian basin axis and the fact of the lateral discontinuity of Vigla limestones and Vigla shales indicate that during the sedimentation of these two Formations there was a restriction along the paleo basin axis, probably due to synsedimentary transfer fault activity. Forty-two (42) samples from Vigla shales were analyzed for their content in CaCO3 and TOC, showed that these sediments present poor to fair hydrocarbon potential. In the Arta new cross-section, with a NE-SW direction, the Upper Cretaceous Senonian deposits showed strong deformation that took place during the compressional regime that affected the Ionian basin after sedimentation. This deformation appears stronger in the western part being close to a major thrust, and thus it is possible that this deformation could be responsible for the high secondary porosity of Upper Cretaceous deposits. Microfacies analysis of these deposits showed in general that deep-sea depositional environments prevailed, nevertheless in a few cases indications for the presence of environments with a shallow character imply the existence of isolated carbonate platforms close to the studied sections. In the studied sections with an E-W direction, no lateral changes were observed in the depositional conditions within the same Formation introducing standard depositional conditions across the paleo basin.

“…Others have proposed that the basins were originally broad sag basins that were later tilted and faulted (Rodger, 2003; Schlische and Withjack, 2005). The tectonic evolution of rift basins has been studied by many researchers in different locations in the world such the Fushan Depression in China (Li et al., 2016), Luanping basin in northeast China (Zhu et al., 2016) and the eastern Ionian Basin, southwestern Greece (Bourli et al., 2019).…”

Study of three dimension seismic data of Merjan survey, central Iraq has showed that the Jurassic – Cretaceous succession is affected by faulting system. Seven major normal faults were identified and mapped. Synthetic traces calculated from sonic and density logs of the well Me-1. Two exploration wells were drilled in the area Me-1 and Wkf-1 wells. The area is characterized by extension phase led to graben system forms rift sub-basin. The structural components of rift sub-basin has identified and visualized in three dimensions. Discussion about the effect of this system on the sedimentary package has been presented. Faulting framework can be divided into two groups: the first affects the Jurassic and lower Cretaceous rocks and the second affects the upper Cretaceous and lower Tertiary rocks. The first group is associated with the post rift thermal sag, passive margin progradation and gravitational collapse (lower Jurassic – mid Turonian 190–92 ma); approximately during the Sargelu – NahrUmr depositional time. The second group is limited and is associated with the rifting creating the Euphrates graben as collision wanes (Late Turonian – Maastrichtian 90–70 Ma) approximately during the Tanuma shale/Sadi – Shiranish depositional time.

This study integrates provenance and statistical data, along with published sedimentological results, applied on the Lower Oligocene submarine‐fan deposits in Pindos foreland basin. Twelve outcrops were analysed using conglomerate clast composition, petrographic and statistical analysis and this integration suggests that the studied deposits were sourced by the Pindos Orogen. Conglomerate clast composition analysis suggests that the studied deposits contain mainly limestone clasts, followed by sandstone and chert clasts. This conclusion is further supported by the petrographic and cathodoluminescence analyses that have been conducted on the conglomerate matrix and, additionally, suggest the influence of a low‐grade metamorphic source. Potential source rock candidates in the Pindos Orogen that provided the detritus in the succession are represented by the Mesozoic carbonates (limestone and chert), the Cenozoic transitional (mixed carbonate and siliciclastic) and the Cenozoic clastic submarine‐fan deposits (sandstone). The rock units of Pelagonian zone likely represent the low‐grade metamorphic source rock. The principal component and cluster analysis of clast lithologies suggest the existence of three compositional clusters, with the first one being controlled by black chert clasts, the second one by sandstone clasts and the third one by limestone and red chert clasts. The upward increase of chert and lithic fragment abundances is ascribed to the progressive unroofing of the Pindos orogenic source regions. This study utilizes the Pindos foreland basin as an example to unravel the contribution of orogenic processes on sedimentary provenance of the adjacent pro‐foreland basins. Furthermore, this study highlights the advantage of implementing a multi‐faceted approach, including statistical treatment in sedimentary provenance.
