Elazığ ili ve çevresinin çizgisel yapılarının gravite verisine sınır analizi teknikleri uygulanarak belirlenmesi

Öz

Gömülü 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

Abstract

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.
