Strontium isotopic and micropalaeontological dating used to help redefine the stratigraphy of the neotectonic Hatay graben, Southern Turkey

Öz:
Güney Türkiye'deki Hatay bölgesinde ortaya konulan stratigrafi eksik ve problemlidir. Ölü Deniz Fay Zonu, Doğu Anadolu Fay Zonu ve Kıbrıs yayı arasında aktif olarak deformasyon geçiren kıtasal kabuğun bulunduğu alanın tektonik önemi ve son günlerde çalışma bölgesi üzerine oluşan ilgi dolayısıyla, bšlgedeki Neojen sedimanter istifin yeniden belirlenerek litostratigrafik adlamasının standartlaşması gerekmektedir. Bu inceleme, mikropaleontolojik ve ilk olarak yapılan stronsiyum yaşlandırması ile yeni saha verlerinin kullanılması ve önceki çalışmaların yeniden gözden geçirilmesi şeklinde güney Türkiye'deki Hatay bölgesinde yapılan çalışmayı ortaya koymaktadır. Bu çalışmada aynı zamanda bölgenin sedimantolojisi de ortaya konmaktadır. Bölgedeki Neojen yaşlı sedimanlar, bu çalışmada yeniden tanımlanmayacak olan Geç Kretase döneminde bölgeye yerleşen Kızıldağ Ofiyolitlerini üzerler. Bu çalışmanın ilgi odağı, kıtasal çarpışmanın geç dönemi boyunca Paleosen'den Eosen dönemi boyunca gelişen bölgesel karbonat şelf ortamından, Orta Miyosen'de başlayıp günümüze kadar süregelen güncel kıtasal açılma tektoniğin izlerini taşıyan döneme kadar olan Neojen yaşlı örtü kayalarını kapsamaktadır. Hatay grabenindeki Eosen-Pliyosen yaşlı sedimanter örtü, altı formasyon ve bir üyeye ayrılmıştır. Bunlar: Samandağ Formasyonu (Pliyosen), Vakıflı üyesi (Messiniyen), Nurzeytin Formasyonu (Serravaliyen-Tortoniyen, ~13.2-8.6 My), Sofular Formasyonu (Burdigaliyen-Langhiyen), Balyatağı Formasyonu (Akitaniyen-Burdigaliyen), Kışlak Formasyonu (Eosen), Okçular Formasyonu (Eosen). Karasu riftinin bulunduğu kesimlereki benzer sedimanlar, Gökdere Formasyonu (Tortoniyen-Messiniyen), Kepez Formasyonu (Langhiyen), Kıcı Formasyonu (Burdigaliyen), ve Hacıdağ Formasyonu (Paleosen-Eosen) olarak isimlendirilmiştir.

Neotektonik Hatay grabeninin Senozoyik stratigrafisini yeniden belirlemek üzere stronsiyum izotop ve mikropaleontolojik verilerle yaşlandırılması, Güney Türkiye

Öz:
In this paper we report for the Hatay Graben, new micropalaeotology, the first strontium dating and new sedimentology. The previous lack of a modern systematic stratigraphy was problematic for the study of the Hatay region. With the new data combined with the existing literature we evaluate and redefine the lithostratigraphy following international standards. The focus of this paper is on the Neogene cover rocks that record the transition from a regional carbonate shelf environment during Palaeocene to Eocene times, through late-stage continental collision, to recent continental rift tectonics that were initiated in the Middle Miocene and continue to operate to the present-day. The EoceneÐPliocene sedimentary cover of the Hatay Graben is here divided into six formations and one member; Samandağı Formation (Pliocene), Vakıkflı Member (Messinian), Nurzeytin Formation (Serravalian-Tortonian, ~13.2-8.6 Ma), Sofular Formation (Burdigalian-Langian), Balyatağı Formation (Aquitanian-Burdigalian), Kışlak Formation (Eocene), and Okçular Formation (Eocene). Similar sediments of the Karasu Rift are termed the Gökdere Formation (Tortonian-Messinian), Kepez Formation (Langian), Kıcı Formation (Burdigalian), and Hacıdağı Formation (Palaeocene-Eocene). A brief interpretation of the stratigraphical relationships is also given.
