the zagros fold- thrust belt as a part of alpine- himalayan orogenic belt, is one of the most active continental collision zones on the earth, which extends from the tarus mountains in south eastern turkey to the minab fault in the east of the strait of hormoz in southern iran. structurally, its formation is related to the continuing convergent movement between the arabian plate to the southwes...
Abstract Naturally, fractured reservoirs play a considerable part in the study, production, and development of hydrocarbon fields because most Zagros Basin are naturally fractured. Production from those is usually affected by presence system connected fractures. In this Tabnak field on fold–thrust belt at zone Persian plate has been analyzed facies models, folding mechanism analysis to identify...
Introduction The study of lake sediments has been widely used in recent decades to identify past climate and environmental changes. Lake basins have significant spatial and temporal patterns and provide valuable evidences of physical and chemical changes. However, in general, the climate of the Holocene period has been more stable and uniform than previous glacial and interglacial periods. How...
quantitative assessment of relative tectonic activity in the alamarvdasht river basin, south of iran
tectonic processes are major factors controlling landform development in tectonically active areas. in order to evaluate quantitative measurement of tectonic activities in the alamarvdasht basin in the south of iran, six different morphological indices including stream-gradient index (sl), drainage basin asymmetry (af), hypsometric integral (hi), valley floor width-valley height ratio (vf), dra...
biofacies and palaeoecology of the limestone of the jahrum formation in the lar area in the southwest of iran (zagros basin) is addressed in this paper. our detailed analysis of biofacies and palaeoecology shows that the jahrum formation in the studied area were deposited in a carbonate open shelf dominated by heterozoan and, subordinately, photozoan skeletal assemblages. based on analysis of l...
Objective: The Asmari Formation is characterised by alternation thick carbonate and marl sequence of the Oligocene- Miocene in the Zagros Basin, southwest of Iran that were deposited on the shelf of Eastern Paratethys. Methods: This formation is exposed at Tang-e-Khoshk in the Fars subcoastal zone with a thickness of 286 m comprising alternation of medium and thick to massive bedded carbonates,...
The Kermanshah Ophiolite Complex (KOC) lies in the structural – tectonic zone of western Iran in northern part of Zagros main thrust and is a part of highly dismembered Kermanshah – Panjvin Ophiolitic belt. The best outcrops of the sheeted and isolated dykes in this complex are present in south of Sahneh area. They are basic in composition. The geochemical studies show parent magma is in its in...

در میدان نفتی مارون، جنوب غرب اهواز، سازند آسماری ( الیگوسن - میوسن ) غالبا متشکل از سنگهای کرتاسه همراه با میان لایههایی از شیل، ماسه سنگ، آهک ماسه ایی و آهک رسی است که به صورت پیوسته روی شیلهای سازند پابده و با پیوستگی در زیر نهشتههای سازند گچساران قراردارد. فونایی نسبتا متنوع شامل فرمهای مختلف فرامینیفرهای بنتونیک و پلانکتونیک در نهشته های سازند آسماری در چاه 312 میدان نفتی مارون شناسایی شده...
Natrix natrix (Linnaeus, 1758) is a common species distributed from Central Europe to Asia. In this range, it forms four subspecies that include several mitochondrial evolutionary lineages. One of the lineages, so-called mtDNA lineage 8, has wide distribution Baltic area Anatolia and Kazakhstan. Anatolia, meets others, however, their occurrence unclear, especially in south-eastern Türkiye where...
