Abstract

In this study, in order to determine relative tectonic activity of the Honaz Fault, geomorphic indices such as triangular facets, drainage basin asymmetry (AF), hypsometric integral (HI), drainage basin shape (Bs), ratio of valley-floor width to valley height (Vf), and mountain front sinuosity (Smf) have been calculated. The results of the indice analysis were evaluated and then index of the relative tectonic activity (Iat) were re-evaluated. Base on the different Iat values, the results were divided into four classes that range from the relatively highest to the relatively lowest tectonic activity. The drainage basin area between Honaz Fault and Mount Honaz is an ideal place to test relative tectonic activity. The Honaz fault that is the north boundary fault of the Honaz Mountain has been divided into the Karateke segment and Honaz segment. The indice values calculated from these segments are triangular facets (Lf / Ls: 0.3-0.46), AF (32-77), HI (0.1-0.6), Vf (0.08-0.7), Bs (1.53-5.06) and Smf (1.12-1.41). The results of this study exhibit the presence of high to very high tectonic activity especially in the central part of the Honaz Fault. Based the results, the neotectonics played an important role in geomorphic evolution of this part of the Honaz Mountain. In addition to the results obtained, evidence of seismic activity, travertine occurrences due to thermal springs and alluvial fans in front of fault zones support high tectonic activity in the region.

Özet

Bu çalışmada, Honaz fayının göreceli tektonik aktivitesinin belirlenmesi için, dağ önü sinüslülük oranı (Smf), üçgen yüzler, vadi taban genişliğinin vadi yüksekliğine oranı (Vf), drenaj havzası asimetrisi (AF), hipsometrik integral (HI) ve drenaj havzası şekli (Bs) gibi jeomorfik indisler hesaplanmıştır. İndis analizlerinin sonuçları değerlendirilmiş ve daha sonra göreceli tektonik aktivite indisi (Iat) olarak tekrar değerlendirme yapılmıştır. Farklı Iat değerlerine dayanarak, sonuçları nispeten en düşükten en yüksek tektonik aktiviteye kadar dört sınıfa bölünmüştür. Honaz Fayı ile Honaz Dağı arasındaki drenaj havzası alanı, göreceli tektonik aktiviteyi test etmek için ideal bir yerdir. Honaz Dağı'nın kuzey sınır fayı olan Honaz fayı morfolojik olarak Karateke ve Honaz segmentlerine ayrılmıştır. Bu iki segmentte hesaplanan indis değerleri, Smf (1.12-1.41), üçgen yüzeyler (Lf/Ls: 0.3-0.46), Vf (0.08-0.7), AF (32-77), HI (0.1-0.6) ve Bs (1.53-5.06)’dır. Bu çalışmanın sonuçları Honaz Fayının özellikle orta kesimlerinde çok yüksek ve yüksek tektonik aktivitenin varlığını ortaya koymaktadır. Araştırmanın sonucu, Honaz Dağı’nın bu bölümünün jeomorfik evriminde neotektonizmanın önemli bir rol oynadığını göstermektedir. Elde edilen sonuçların yanı sıra bölgedeki sismik aktivite, sıcak su kaynaklarına bağlı traverten oluşumları ve fay hatlarının önündeki alüvyon yelpazelerinin varlığı bölgedeki yüksek tektonik aktiviteyi desteklemektedir.
