ORTA ANADOLU BÖLGESİ ATMOSFER-KABUK ARA YÜZEYİ KABUK YOĞUNLUĞUNUN FRAKTAL BOYUTLAR İLE BELİRLENMESİ

Öz

Bu çalışma, Orta Anadolu bölgesine ait Serbest Hava Gravite verisindeki topoğrafik etkileri rejyonal ölçekte en aza indirgeyen atmosfer-kabuk ara yüzeyi kabuk yoğunluğu değerinin belirlenmesini amaçlamıştır. Bu amaç doğrultusunda bölgenin yükseklik verileri kullanılarak Serbest Hava Gravite verilerinin çeşitli kabuk yoğunluğu değerleri için topoğrafik etkilerinin indirgemesi yapılmış ve uygulanan her bir yoğunluk değerine ilişkin basit Bouguer Gravite anomalileri elde edilerek bunların Fraktal boyutları hesaplanmıştır. İndirgeme işlemlerinde kullanılan değişken kabuk yoğunluğu değerlerine karşılık elde edilen basit Bouguer Gravite anomalilerinin Fraktal boyutlarının grafiksel analizleri sonucunda Orta Anadolu bölgesi Serbest Hava Gravite verilerindeki topoğrafik etkiyi rejyonal ölçekte minimize eden atmosfer-kabuk ara yüzeyi kabuk yoğunluğu değeri 2.59 gr/cm3 olarak hesaplanmıştır.

DETERMINATION OF ATMOSPHERE-CRUST INTERFACE CRUSTAL DENSITY OF THE CENTRAL ANATOLIA REGION BY THE FRACTAL DIMENSIONS

Öz

This study aimed to determine the crustal density value at the atmosphere-crust interface that minimizes the topographic effects in the free air gravity data of the Central Anatolia region on a regional scale. For this purpose, using the elevation data of the region, topographic effects were reduced for various crustal density values of Free Air Gravity data and fractal dimensions were calculated of the simple Bouguer Gravity anomalies obtained for each density value. As a result of the graphical analysis of the fractal dimensions of the simple Bouguer Gravity anomalies obtained in response to the variable crustal density values used in the reduction processes, the crustal density value at the atmosphere-crust interface, which minimizes the topographic effect in the free air gravity data on a regional scale, was calculated as 2.59 gr/cm3 for the Central Anatolia region.
