Sixth millennium BC Dalma ceramics from the northwestern and central Zagros have previously been described as beingimpossible to distinguish using decorative style analysis in spite of the great distance between the two regions. In thisstudy, petrographic (thin section) analysis and a small-scale electron microprobe project was carried out on the ceramicsof the two regions, as well as a small s...

There are various vegetation sampling methods regarding objectives of Management at forests. To aim of this study, we undertook a comparative study at Shineh Ghelaee protected forest at middle Zagros using single-scale sampling, single-scale sampling based on transects, and multi-scale sampling methods to investigate the herbaceous layer diversity. In order to know the situation of the region a...

we usewe use ml shear wave velocity to derive a high resolution 2d ml shear wave velocity map for the iranian plateau. the ml amplitudes and arrival times are routinely measured for the calculation of local magnitude. ml shear wave velocity is very sensitive to the lateral change of crustal thickness and switches between the velocity of lg and sn waves. an lg wave will die out as soon as encoun...

تپه ی کلنان متعلق به دوره ی مس و سنگ میانه است و در شرق استان کردستان واقع شده است. داده های به دست آمده از گاهنگاری مقایسه ای و مطلقِ این تپه نشان دهندۀ استقرار در آن از 4050 تا 3650 ق.م است. به دلیل نبود لایه نگاری محوطه های مس و سنگ در استان کردستان در مقایسه با سایر نقاط ایران، تپه ی کلنان در شهرستان بیجار لایه نگاری شد. در اینجا عاوه بر گاهنگاری نسبی و مطلق، گونه شناسی مواد فرهنگی نیز مورد ...

Climate change has a great impact on the species distribution range and many endangered plant species. Fritillaria imperialis as a species that is native to Central Zagros, Iran is a medicinal plant with great ecological and commercial profits. Its population has decreased considerably and the species would be endangered in later decades. Understanding the habitat needs of this species, evaluat...

In this study, the active tectonics, paleoseismicity, and seismic hazards of Doroud Fault are examined through high-resolution satellite image interpretations, field investigations, outcrop trench excavations, dating geochronology samples. The (DF), one essential segments Main Recent in northern margin Zagros mountain range, has a historical instrumental background high seismicity. We present f...

In the current study, conservation strategies were employed for the spatial analysis of forest fragmentation and field assessment approaches in a forest landscape of Central Zagros, in the western part of Isfahan province, Iran. Vegetation and soil properties were accordingly studied in 15 forest sites with various densities including dense, semi-sparse and sparse-forests with 839.2 km2. In the...

Introduction The final phase of Late Paleolithic of Zagros Mountains has been introduced as the Zarzian of the Epipaleolithic (EP), which was defined based on the assemblage from type site of Zarzi Cave in Iraqi Kurdistan. This techno-complex has been much less investigated and introduced in comparison to the earlier groups of Upper Paleolithic. The Zarzian is a microlithic industry with smal...
