“…The boundary between the two formations is marked by sea level markers, as lithodome holes (Figure 5c), which indicate the presence of an ancient coastline (Figure 3a), similar as interpreted by Öğretmen, Cipollari, et al (2018). Considering the 1,500 m of elevation of the upper part of the Sarıkavak Formation, and the end of the sedimentation that occurred around 457 ka (Öğretmen, Cipollari, et al, 2018; Öğretmen, Ferezza, et al, 2018), we relate this terrace level to the first sea level high‐stand occurred after the end of marine sedimentation (MIS11—ca. 425 ka).…”

“…This high‐resolution uplift trend for the Pleistocene phase of uplift at the CAP southern margin is at odds with recent reconstructions that place the uplift phase prior to the Pliocene (Fernández‐Blanco et al, 2019) or during the late Miocene (Meijers et al, 2018). Both these reconstructions do not consider the presence of middle Pleistocene marine deposits up to 1,500 m of elevation in the Gülnar area (Öğretmen, Cipollari, et al, 2018; Öğretmen, Ferezza, et al, 2018). The Pleistocene high‐resolution uplift trend of the CAP southern margin, as provided in this paper, is consistent with the surface uplift signals of thermo‐mechanical models for experiments of subduction‐collision systems (Duretz & Gerya, 2013).…”

“… The CAP southern margin is characterized by a staircase morphology defined by the presence of at least seven marine terraces (T1–T7), from 1,400 m down to 30 m of elevation, due to the interplay between sea‐level changes and tectonic uplift. All of them developed after the deposition of the youngest marine deposits (late middle Pleistocene) recently recognized in the Gülnar area (Öğretmen, Cipollari, et al, 2018; Öğretmen, Ferezza, et al, 2018), which were subsequently uplifted at 1,400–1,500 m of elevation. The LEM allows us to correlate the T1–T7 marine terraces that were recognized in the field and through the analysis of a 12 m resolution TanDEM‐X digital elevation model, with highstands that occurred from MIS 11 (ca. 425 ka) to MIS 3 (ca.…”

“…Recently, lower‐to‐middle Pleistocene deep‐marine deposits (Sarıkavak Formation) were recognized at the CAP southern margin, around the city of Gülnar, at elevations between 1,000 and 1,500 m (Öğretmen, Cipollari, et al, 2018; Öğretmen, Ferezza, et al, 2018). In the Gülnar area, the Pleistocene deep‐marine deposits unconformably cover the Miocene limestones of the Mut Fm.…”

The southern margin of the Central Anatolian Plateau (CAP) records a strong uplift phase after the early Middle Pleistocene, which has been related to the slab break-off of the subducting Arabian plate beneath the Anatolian microplate. During the last 450 kyr the area underwent an uplift phase at a mean rate of ~3.2 m/kyr, as suggested by Middle Pleistocene marine sediments exposed at ~1500 meters above sea level. These values are significantly higher than the 1.0-1.5 m/kyr estimated since the Late Pleistocene, suggesting temporal variations in uplift rate. To estimate changes in uplift rate during the Pleistocene we studied the marine terraces along the CAP southern margin, mapping the remnants of the platforms and their associated deposits in the field, and used the TerraceM software to identify the position and elevation of associated shoreline angles. We used shoreline angles and the timing of Quaternary marine sedimentation as constrains for a Landscape Evolution Model that simulates wave erosion of an uplifting coast. We applied random optimization algorithms and minimization statistics to find the input parameters that better reproduce the morphology of CAP marine terraces. The best-fitting uplift rate history suggests a significative increase from 1.9 to 3.5 m/kyr between 500 and 200 kyr, followed by an abrupt decrease to 1.4 m/kyr until the present. Our results agree with slab break-off models, which suggest a strong uplift pulse during slab rupture followed by a smoother decrease.

ÖZDoğu Akdeniz'de epibatiyal derinlikte oluşmuş en genҫ denizel ҫökeller Kalabriyen-Kibaniyen yaşlı olup, Orta Anadolu Platosu'nun güney kesiminde yakın zamanda keşfedilmiştir. Dolayısıyla Kalabriyen-Kibaniyen yaşlı planktik foraminiferlerin yaşadığı Doğu Akdeniz'in o döneme ait ekolojisi bu zamana kadar incelenmemiştir. Bu ҫalışma Türkiye'nin güneyinde Mersin civarında bulunan Kalabriyen ve Kibaniyen yaşlı iki adet denizel birime ait planktik foraminifer topluluklarını ve Doğu Akdeniz'in yüzey sularının sıcaklık ve besin gibi ҫevresel parametreler bağlamında ekolojik özelliklerini ortaya koymaktadır. Burada planktik foraminiferler arasındaki baskın toplulukları belirlemek iҫin Küme Analizi, ҫok değişkenli istatiksel verisetindeki etkin ekolojik değişkenleri belirlemek iҫin ise Temel Bileşen Analizi uygulanmıştır. Ҫok değişkenli istatiksel analiz sonuҫları, Kalabriyen yaşlı Doğu Gülnar denizel biriminin Globorotalia, Globigerinella, Globigerina, ve Orbulina olarak dört ana toplulukla temsil edildiğine işaret etmektedir. Ҫökelme ortamının Kibaniyen yaşlı daha genҫ kesimi olan Tol istifinin ise Globigerinoides ve Globigerinella obesa, Orbulina ve Globigerinoides, ve Orbulina olmak üzere üҫ ana toplulukla temsil edildiğine işaret etmektedir. Topluluklar arasındaki istatistiksel ilişki incelendiğinde Doğu Gülnar denizel birimi iҫin üҫ temel ekolojik faktör (sıcaklık, besin, kıyıdan uzaklık), Tol birimi iҫin ise tek bir ekolojik faktör (su derinliği) tanımlanabilmiştir. Bu durum, kesitlerin farklı iklimsel koşullarda oluştuğunu göstermektedir.
