    This study discusses the composition and age of calcarenite deposits and aeolianite overlying the upper Cretaceous ophiolites in the eastern Mediterranean north of the Asi River Delta. They record the Mediterranean–Red Sea water connection in the Late Pleistocene. Petrographic analysis and microfossil determination showed that these deposits are classified as micritic calcarenite and biocalcarenite, indicating deposition in a high-energy shoal environment and carbonate aeolianite with abundant rhizoliths as residuals of rootlet calcification. The invasive species of Amphistegina lobifera Larsen and Peneroplis pertusus (Forskal) found in the calcarenite and aeolianite make it clear that the Indo-Pacific Ocean waters reached the Levantine Sea basin during the periods MIS 5e and/or MIS 5c by following a palaeo-channel along the Gulf of Suez.

    Raised braided stream gravels on Mount Keldağ, Hatay (Eastern Mediterranean coast, Turkey): implications of transformation to beachrock and ensuing tectonic uplift
    (Springer Science and Business Media B.V., 2019) Erginal, Ahmet Evren; Polymeris, Georgios S.; Karataş, Atilla; Giannoulatou, Valeria; Şahiner, Eren; Meriç, Niyazi; Erenoğlu, Oya
    On the seaward northwest slopes of Mount Keldağ, Hatay, the combination of an unconformably overlapping sequence of cemented gravels on a wave-cut platform, and a raised notch and irregular pits left by grazing molluscs on the walls of this notch, carved in an NE-trending high-angle fault plane, retain the record of raised braided stream gravels transformed into beachrock. From the OSL ages, this study reveals that deposition of this sequence occurred between 232.30 ± 31.62 and 214.01 ± 27.42 ka during the penultimate interglacial. The four distinct facies identified are massive matrix-supported conglomerate, massive to crudely stratified gravel, cross-stratified gravel, and clast-supported open-work gravel. Extending to the paleo-coastline during the MIS7 highstand, this sequence was cemented by carbonate and iron-oxide cements and records an uplift of around 0.1 mm/year up to the present. © 2019, Springer Nature Switzerland AG.
