Abstract (2. Language): 
The purpose of this study is to elucidate the structural style of Azmar structure, a major anticlino-rium within the imbricate partition of Zagros fold-thrust belt in northeastern Iraq. Structural analysis of this anticli-norium demonstrated that it consists of four main NNW-SSE trending anticlines. They are imbricated SW ward through NE dipping reverse faults merge to a deep seated detachment. Furthermore, analysis of minor folds on hinge and limbs of the main Azmar anticline revealed the versatile style of such minor folds and their opposing vergencies. These features emphasize the role of faulting in development of the major fold and the minor folds. This interpretation has been supported by hinge angularity, as well as by association of hinge and limb disrupting reverse slip mesofaults with those minor folds. Therefore a progressive fault related folding is proposed for Azmar structure in this work.

Abstract (Original Language): 
Bu çalışmanın amacı, kuzeydoğu Irak'taki Zagros Kıvrım-Bindirme Kuşağının kiremit yapılı bölümünde yer alan ve Azmar yapısı olarak bilinen temel antiklinoryumun yapısal tipini ortaya çıkarmaktır. Yapılan yapısal ana¬liz bu antiklinoryumun KKD-SSB doğrultulu dört ana antiklinalden meydana geldiğini göstermiştir. Bunlar KD'ya eğim yapan ters faylarla GB yönünde kiremitlenirler ve derinde bir ayrılma fayı üzerinde birleşirler. Bunun yanında Ana Azmar Antiklinalinin sırt ve kanatları üstündeki küçük kıvrımların analizi bu tip küçük kıvrımların çok yönlü tiplerini ve karşıt yönelimlerini ortaya çıkarmıştır. Bu özellikler faylanmanın ana ve küçük kıvrımların gelişiminde¬ki rolünü açıklar. Bu yorum, ters atımlı mezofaylar ve kestikleri küçük kıvrımların sırt ve kanat ilişkisi kadar sırt açısallığı ile de desteklenmiştir. Bu nedenle, çalışmada Azmar yapısı için aşamalı faya bağlı kıvrımlanma öne¬rilmiştir.
