Западная окраина Центрального Ирана – район Наин – сложена целым рядом мезозойских офиолитовых меланжей, сформировавшихся в позднемеловую эпоху. Разломы Наин и Даррех Дех, прослеженные на изучаемой территории, являются одними из наиболее крупных. Они имеют север-северо-западное простирание и представляют собой правосторонние транспрессионные активные линеаменты. Основной целью исследования является реконструкция тектонических движений с помощью структурного картирования и геометрического анализа структурных особенностей системы разломов Наин и Даррех Дех. При проведении исследования авторами были использованы полевые наблюдения и спутниковые изображения. Структурный анализ показал, что разрывные нарушения образуют сложную сеть, развитие которой прошло две стадии: 1) формирования надвигов в позднемеловую эпоху и 2) реактивации надвигов в правосторонние взбросо-сдвиги в результате транспрессивных движений в позднем миоцене. Разломы Наин и Даррех Дех активны в настоящее время и имеют правостороннее сдвиговое смещение со взбросовой составляющей.

The western margin of Central Iran – the Nain area – is composed of the Mesozoic ophiolitic mélanges deposited during the Late Cretaceous. The Nain and Darrech Deh faults whose trace indicators can be seen in the study area are among the largest faults therein. These faults have a north-northwest strike and are the right-lateral transpressional active lineaments. The main aim of this research is to perform structural mapping and geometric analysis of structural features along the Nain and Darrech Deh fault system. The research was conducted using satellite imagery and field data. The structural analysis showed that the faults comprise a complex network which formed during two stages: 1) thrust faulting in the Late Cretaceous and 2) reactivation of thrust faults in the form of the right-lateral reverse-slip structures as a result of transpressional movements in the Upper Miocene. The Nain and Darrech Deh faults are presently active and exhibit the right-lateral strike slip displacement with a reverse component.
