kuhbanan fault system, as one of the intracontinental faults of central iran, is recognized by considerable seismogenic activities and modern morphotectonics evidences with a strike-slip (reverse component) motion. according to the geometric and kinematics data, kuhbanan fault has been divided into 5 segments (s26, s27, s28, s29, s30) in bahabad region. measured geomorphic indices of ratio of v...

Study area is located in the higher folded belt in the Zagros Mountain in the Iraqi Kurdistan. Analyzed geomorphic indices included sixteen sub basins: the stream gradient index (SL), drainage basin asymmetry (AF), hypsometric integral (Hi), Valley floor width-valley height ratio (VF) and mountain front sinuosity (J) is obtained relative of tectonic activity in the study area. These indices abo...

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...

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...

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...

The aim of this work is to propose a first-order estimate of the crustal and lithospheric mantle geometry of the Arabia–Eurasia collision zone and to separate the measured Bouguer anomaly into its regional and local components. The crustal and lithospheric mantle structure is calculated from the geoid height and elevation data combined with thermal analysis. Our results show that Moho depth var...

medicinal species of mountain’s kelavs, scientifically named (kelussia odoratissmia mozaffar.) is an endemic species in iran. kelussia odoratissima is a perennial species and belongs to the umbelliferae. from the ancient times, the local and nomad societies had believed that the species traditionally have anti-ache, anti-inflation and anti-cough effects. seed and root of this species are boiled...

In semiarid climates, a significant component of recharge to basin aquifers occurs along the mountain front. Traditionally called “mountain-front recharge” (MFR), this process has been treated by modelers of basins as a boundary condition. In general, mountain-front recharge estimates are based on the general precipitation characteristics of the mountain (as estimated, e.g., by the chloride mas...
