Abstract

Bu
çalışmada, gömülü bir yapının şekil ve derinliğini eş zamanlı olarak kestiren
bir teknik olan parametrik eğriler tekniği, rezidüel gravite verilerinin
türevlerine uygulandı. Bu metot, kaynağın şekil ve derinliği arasında bir
ilişki kurmak için profil verilerinin karakteristik noktalarını ve orijinini
kullanır. Düşey fay modeli için rezidüel gravite verisinin ikinci dereceden
türevi kullanırken, gömülü küre, yatay silindir, düşey silindir ve yarı sonsuz
düşey dayk modelleri için rezidüel gravite verisinin birinci dereceden
türevleri kullanıldı. Ayrıca, C# dili ve .NET Framework 4.5 kullanılarak bir
yazılım geliştirildi. Yöntem beş sentetik modele uygulandı ve her bir model
için şekil faktörleri belirlendi. Sentetik örneklere ilave olarak, yöntemin
geçerliliğini test etmek için Türkiye’den bir rezidüel gravite haritası
kullanıldı. Çalışma alanından elde edilen üç profil verisine hem önerilen
yöntem hem de güç spektrumu yöntemi uygulandı ve hesaplanan derinlikler birbiri
ile karşılaştırıldı. Son olarak, hesaplanan derinlikler kullanılarak
Erzincan-Çayırlı Baseni’nin üç boyutlu bir modeli oluşturuldu.

Estimation of the Depth and Shape of the Source from Derivatives of Residual Gravity Data Using the Parametric Curves Technique: A Case Study from Erzincan-Çayırlı Region, Turkey

Abstract

In
this study, the parametric curves technique that estimates the shape and depth
of a buried structure simultaneously, was applied to derivatives of residual
gravity data. This method uses the origin and characteristic points of the
profile data to establish a relationship between the shape and depth of the
source. The first-order derivative of residual gravity data was used for buried
sphere, horizontal cylinder, vertical cylinder and semi-infinite vertical dyke
models, whereas second-order derivative of residual gravity data was used for
vertical fault model. Besides, a software was developed to apply the method on
synthetic and field data by using the .NET Framework 4.5 and C# language. This
method was applied to five synthetic models and the shape factors were
determined for each models. In addition to synthetic examples, a residual gravity
map from Turkey was used to test the validity of the method on real data. Both
proposed method and power spectrum method were applied on three profile data
obtained from the study area and estimated depths were compared with each
other. Finally, a 3D model of the Erzincan-Çayırlı Basin was created using the
estimated depths.
