yeraltı yapılarının yerlerinin ve sınırlarının belirlenmesi, yerbilimlerinde
önemli bir problemdir.  Sınır belirleme
yöntemleri olarak bilinen birçok süzgeç, potansiyel alan verileri
uygulamalarında kullanılmaktadır. Bu çalışmada, 
önce yapay olarak oluşturulan yeraltı modeline süzgeçler uygulanmıştır.
Elde edilen sonuçların yorumlanmasıyla, yöntemlerin becerisi tartışılmıştır.
Gerçek arazi verisi uygulamasında, Doğu Anadolu bölgesinde yer alan, Elazığ ili
ve çevresini içine alan bölgenin, Bouguer gravite anomali verisine sınır
belirleme yöntemlerinin uygulanmasıyla, bölgedeki ana faylar ve fay sistemleri
belirlenmeye çalışılmıştır. Bölgenin hakim tektonik yapıları olan Doğu Anadolu
fayı ve Güney Doğu Anadolu fayı başarılı bir şekilde belirlenmiştir. Bunun
yanında çalışma alanının kuzey kesiminde Elazığ ili ve Elazığ-Pertek-Akpazar
arasında yaklaşık D-B ve GB-KD uzanımlı çizgisellikler belirlenmiştir.

Determination of linear features of Elazığ province and surrounding by applying boundary analyzing techniques to gravity data

Öz

Defining
the location and boundary of the buried features is an important task in earth
science. Many filters, known as edge detection methods, are used in potential
field data applications. In this study, the filters were firstly applied to a
synthetically generated model. The result maps obtained by using the methods to
the gravity anomaly of the model were compared and the skill of the methods
were discussed. In the real data application, main faults and fault systems in
the region have been tried to be determined by applying the boundary detection
methods to the Bouguer gravity anomaly data of Elazığ province and its
surroundings in Eastern Anatolia region. The East Anatolian fault and the South
East Anatolian fault, which are the dominant tectonic structures of the region,
have been successfully determined. In addition to this, approximately E-W and SW-NE
extensional lineaments were determined between Elazığ province and
Elazığ-Pertek-Akpazar in the northern part of the study area.
