“…This zone is probably equivalent to the Pseudorhipidionina laurinensis TRZ of Saint-Marc (1975), together with the P. dubia -P. laurinensis TRZ of Chiocchini et al (2001) and P. dubia -B. bentori Cenozone of Tasli et al (2006).…”

“…However, the Wynd (1965) scheme is still used as a reference for most biostratigraphic studies in the Zagros, and is here correlated with biozonation schemes developed for other parts of the world (e.g. Saint-Marc, 1975;Chiocchini et al, 2001;Tasli et al, 2006). Based on benthic foraminifera and following the Wynd (1965) biozonation scheme, five biozones were identified ( Figs.…”

“…Chiocchini et al (2001) considered this as the TRZ of P. dubia -P. laurinensis for the upper part of the Middle Cenomanian and the upper part of the Upper Cenomanian of central Italy. Tasli et al (2006) considered this zone (TRZ of P. dubia -P. laurinensis) as the Cenozone of P. dubia and Biconcave bentori for south Turkey.…”

Cretaceous carbonates host major hydrocarbon reserves in SW Iran and elsewhere in the Arabian Plate. Tectonic activity combined with eustatic sea-level changes resulted in periodic exposure of these carbonates which were subsequently modified by meteoric diagenesis under a warm and humid climate. Long-term exposure led to the formation of several disconformity surfaces within the middle Cretaceous succession which had important effects on the interval's reservoir characteristics. These disconformity surfaces in the Dezful Embayment were investigated using microfacies, diagenetic and geochemical studies at five subsurface sections. Facies differences across these boundaries, together with features such as karstification, palaeosol development and collapse-dissolution breccias, were used to identify emergent surfaces. Stable oxygen and carbon isotope ratios and trace element profiles indicate intense meteoric diagenesis. Disconformities were dated using biostratigraphic studies. The results indicate the presence of two major erosional disconformities: one is located at the Cenomanian -Turonian boundary separating the middle Sarvak Formation from its upper part; and the other is in the mid-Turonian at the boundary between the Sarvak and Ilam Formations. The latter disconformity is correlatable throughout the Arabian Plate.

“…The individual clasts and blocks have a brownish mudrock (shale/phyllite) matrix, which is lithologically similar to the meta-mudrock forming the highest levels of the underlying intact platform succession (Figures 5 and 6(a), (b)). A similar unit occurs between the Mesozoic carbonate platform and ophiolitic rocks in many areas of the Taurides (Yavça-type facies) (Parlak & Robertson, 2004;Robertson et al, 2012;Taslı, Özer, & Koç, 2006).…”

We have carried out a several-year-long study of the Amanos Mountains, on the basis of which we present new sedimentary and structural evidence, which we combine with existing data, to produce the first comprehensive synthesis in the regional geological setting. The ca. N-Strending Amanos Mountains are located at the northwesternmost edge of the Arabian plate, near the intersection of the African and Eurasian plates. Mixed siliciclastic-carbonate sediments accumulated on the north-Gondwana margin during the Palaeozoic. Triassic rift-related sedimentation was followed by platform carbonate deposition during Jurassic-Cretaceous. Late Cretaceous was characterised by platform collapse and southward emplacement of melanges and a supra-subduction zone ophiolite. Latest Cretaceous transgressive shallow-water carbonates gave way to deeper-water deposits during Palaeocene-Eocene. Eocene southward compression, reflecting initial collision, resulted in open folding, reverse faulting and duplexing. Fluvial, lagoonal and shallow-marine carbonates accumulated during Late Oligocene(?)-Early Miocene, associated with basaltic magmatism. Intensifying collision during Mid-Miocene initiated a foreland basin that then infilled with deep-water siliciclastic gravity flows. Late Miocene-Early Pliocene compression created mountain-sized folds and thrusts, verging E in the north but SE in the south. The resulting surface uplift triggered deposition of huge alluvial outwash fans in the west. Smaller alluvial fans formed along both mountain flanks during the Pleistocene after major surface uplift ended. Pliocene-Pleistocene alluvium was tilted towards the mountain front in the west. Strike-slip/transtension along the East Anatolian Transform Fault and localised sub-horizontal Quaternary basaltic volcanism in the region reflect regional transtension during Late Pliocene-Pleistocene (<4 Ma).

“…It is known in Lower Aptian, Bedoulian Stage, strata in the Karst Dinarides with zonal foraminifers: Praeorbitolina cormyi, P. wienandsi and Mesorbitolina lotzei (Veli c, 2007). V. murgensis occurs in southern Turkey in Lower Aptian carbonates with Praechrysalidina infracretacea (Tasli et al, 2006).…”
