This study provides a multi-disciplinary overview of the seismology and geodetic data with tectonics analysis in order to provide an evaluation stress trajectories, probabilistic fault rupture hazard assessment. Based on different scenarios obtained from comparison several overviews their interpretation, we investigated kinematics active structural zones. In this study, magnitudes directions se...

the occurrence of soil water repellency and its intensity were studied in three sites under pinus teada, petrocarya fraxinifolia and sombucus ebulus in talesh township, western part of guilan province. seventy nine undisturbed soil samples from 0–5 cm depth were collected for water repellency and water-soil contact angle to be determined in a dry season. soil water repellency was assessed using...

feldspar grains, as a significant provenance indicator, of two terrigenous formations from central iran, the upper red formation, and moghan area, zivah formation, are used for provenance determination and the study of transportation and depositional history. the upper red formation (urf) is volumetrically the most important siliciclastic unit of the central iran and zivah formation (zf) repres...

Feldspar grains, as a significant provenance indicator, of two terrigenous formations from Central Iran, the Upper Red Formation, and Moghan area, Zivah Formation, are used for provenance determination and the study of transportation and depositional history. The Upper Red Formation (URF) is volumetrically the most important siliciclastic unit of the Central Iran and Zivah Formation (ZF) repres...

introduction one of the factors affecting in the control of environmental hazards, is the stability of the structure landforms. human activities especially in the case transportation, and also the need to expand it in different areas, can significantly affect on the region geomorphologic structures and causing high damages on life and financial. as a result, human activity can operate as a fact...

The purpose of this study is to determine the woody species diversity in Sweet chestnut tree, Hazel-tree and Italian cypress ecosystems in the Guilan forests. A lozeng 0.5 ha sample plot was selectively established on each site. In the Sweet chestnut ecosystems , 4 sites were classified, whereas 10 sites of Hazel tree and Italian cypress ecosystems were classified based on species composition. ...

Tectonic stresses governed by the Arabia – Central Iran collision are transferred throughout Iranian Plateau. The orientation of maximum horizontal stress (σ 1 ) significantly changes (~90°) in Persian block NW Iran. However, exact spatial extent and boundary conditions for these poorly defined. This study investigates late Cenozoic regime a key region including Mahneshan Mianeh Basin (MMCB), G...
