Doğu Pontidler, Arabistan-Avrasya levhalarının yakınlaşmasından dolayı sıkışmalı fay geçişi (transpressional) içerisinde, 0,5 mm’den fazla bir hızla “push-up” geometrisiyle yükselen aktif bir dağ kuşağıdır. Söz konusu yükselim, Karadeniz’e cephe dağ önlerinde ilk kez bu çalışmada haritalanan ara aşmalı (en échelon) geometrili eğim/verev atımlı normal fay segmentleri tarafından karşılanmaktadır. Yaklaşık 65 km uzunluğunda ve 1 km genişliğinde 9 farklı parçadan oluşan Güneydoğu Karadeniz Fay zonu boyunca yapılan kinematik çalışmalarda eğim açıları 60^o-90^o ve kayma açıları (rake) 32^o-90^o arasında değişen ve sahil kesimindeki dağ önlerini denetleyen çok sayıda fay düzlemi ölçülmüştür.  Bu çalışmada varılan sonuçlar, (i) Doğu Pontidler’in kıyı şeridinde gözlenen bu faylanma, başlangıçta σ1’in yatay konumlu olduğu sıkışmalı bir ortamda oluşan bindirme fayı ve ters bileşenli doğrultu atımlı faylar nedeniyle kabuk kalınlığını artırdığını ve bunun sonucunda yatayda olan σ1 düşey konuma geçerek eski zayıflık zonlarının normal faylar şeklinde yeniden çalıştığını, (ii) Güneydoğu Karadeniz Fayı olarak tanımlanan bu zayıflık zonunun Kuvaterner’de yüzey faylanmasıyla sonuçlanmış depremler ürettiğini ve bu nedenle Türkiye Diri Fay Haritası’nda “Kuvaterner Fayı” sınıfında değerlendirilmesi gerektiğini göstermektedir.

Field Evidence for Southeast Black Sea Fault of Quaternary Age and Its Tectonic Implications, Eastern Pontides, Turkey

Öz

The Eastern Pontides, which is the under transpressional deformation zone, is an active mountain belt in northern Turkey that has been uplifting at a rate of more than 0.5 mm/year, along with push-up geometry. This uplift is accommodated by the dip/oblique slip normal fault segments of an en-echelon geometry mountain front mapped here for the first time. According to our geological mapping studies, the Southeast Black Sea Fault zone is about 65 km total long and more than 1 km wide and comprises nine fault segments. In the kinematic analysis conducted along the fault zone, fault planes have dip angles between 60^o-90^o to the north. The measured fault planes have rake angles range from 32^o to 90^o. Our findings indicate that (i) the faulting observed in the mountain front of the Eastern Pontides, the crustal thickness has increased due to thrust component strike-slip faults formed in a compressive regime where σ1 was horizontal at the initially, as a result of this, σ1 which is the horizontal position went into a vertical position, and lastly the former weakness zones were re-activated as normal faults, (ii) this weakness is defined as an Southeast Black Sea Fault that produces earthquakes have resulted in surface rupture in the Quaternary and therefore this fault should be considered in the class of “Quaternary Fault” in Turkey’s active fault maps.The Eastern Pontides, which is the under transpressional deformation zone, is an active mountain belt in northern Turkey that has been uplifting at a rate of more than 0.5 mm/year, along with push-up geometry.
