: Recent detailed examination of the internal deformation of the Turkish-Iranian Plateau in the hinterland of Bitlis-Zagros Suture Zone, which is related to the collision of the Arabian and Eurasian plates, indicates multiple intersection points between the right-and left-lateral strike-slip structures explained by an inevitably broad left-lateral strike-slip shear zone, the Anatolian Diagonal. The faults bounding and internally deforming the Anatolian Diagonal were closely examined by using high-resolution satellite images, focal mechanism solutions of the earthquakes, and published seismic reflection data in the offshore areas. The Anatolian Diagonal is a NE-SW trending left-lateral shear zone having a 170 km width between the Central Anatolian and the East Anatolian fault zones and an 850 km length between Erzincan and the Cyprus Arc. It has at least four intersection points with the right-lateral North Anatolian Fault Zone and the Southeast Anatolian-Zagros Fault Zone. As the offshore continuation of the Ecemiş-Deliler Fault of the Anatolian Diagonal, the Biruni Fault reaches the Cyprus Arc and Piri Reis (Mediterranean) Ridge Front west of Cyprus. This structure creates a restraining stepover with the left-lateral Antalya-Kekova Fault Zone and causes NW-SE trending thrusts of the Florence Rise and Antalya Thrust in the Antalya Basin. There is another restraining stepover between the Antalya-Kekova Fault Zone and the Pliny-Strabo Fault Zone, where the thrust-controlled northern margin of Rhodes basin developed. In

The study investigated phosphate-rich sedimentary rocks in the Late Cretaceous Karababa Formation in the Mardin-Mazıdağ region, which represents the northern part of the Arabian Plate. The stratigraphic succession is divided into three members as i) Karataş: ellipsoidal gray-colored, largely weathered, fossiliferous shelly micritic limestone, ii) Ekinciler: dolomitic cherty limestone interbedded with marls, and iii) Evciler: argillaceous limestone with common phosphatic horizons. Large numbers of hand samples, collected from the outcrop successions, were carefully studied with optic microscopy (OM) and scanning electron microscopy (SEM). They indicate the presence of optical isotropic pelletic apatite minerals (37% P2O5), bone fragments, fish teeth, and invertebrate fossil fragments like brachiopod shells in phosphorite rocks and micritic limestone. The phosphorites in the Karababa Formation are interpreted to have been deposited in a very shallow, near-shore or low energy environment.

Total trace element concentrations in apatite minerals range from 2436 ppm to 2456 ppm, with total concentrations normalized to chondrite (ppm) higher than North America Shale Composite (NASC) at 664.98 ppm for P, 208.33 ppm for Sr and 33.66 ppm for Y. Common occurences of apatite, palygorskite/sepiolite, and smectite clay minerals in various sections of the Karababa Formation were interpreted as authigenic minerals in the marine environment. However, occurrences of mixed layered clay minerals were interpreted as a result of neoformation and/or transformation processes. The phosphate occurences in the Karababa Formation are considered to form due to mineral formation processes occurring via biogenic and biogeochemical activities that developed with the changes in sea level linked to tectonic movements associated with the evolution of the Neotethyan ocean during the Upper Cretaceous period.
