Introduction The Islamic Republic of Iran (Figure 1) has an area of 1,648,000 km 2 and a population of 65 million people (1995 estimate). The country has arid and semiarid climates and the occurrence of rainfall is unreliable, with a coefficient of variation as high as 70%. The average annual precipitation over the country is around 250 mm. Two mountain ridges, the Alborz and Zagros (Figure 1),...

The Main Recent Fault is a major right-lateral strike-slip fault in the western Zagros mountains of Iran. geodetic and geological studies estimate low slip rate 1–6 mm/yr at an unknown depth which, when combined with non-ideal geometry, makes difficult but interesting target for InSAR analysis. This analysis would further cement estimated provide opportunity to base locked seismogenic zone, bot...

Charcoal canker of oak, which has recently increased in southern Iran, could pose a serious threat to the entire forest ecosystem near future. In addition, it seems that climate change and its consequences, such as drought regions have exacerbated this phenomenon. Consequently, objective study was identify fungal pathogens cause charcoal disease oak forests South Zagros. It also sought find ass...

Abstract. Recognition of a new angular unconformity and the synthesis detrital zircon U–Pb (U–Th) / He provenance records, including double dating, from NW Zagros region elucidate basin dynamics foreland wedge-top intermontane units, as well tectonic processes in source terranes response to different geodynamic phases. In this contribution, we present field observations data hinterland basins r...

the rijab area with189 square kilometers is located in northwest of zagros and north of sarpol zahab city. its main skeleton is made of hard and resistive layers of shahbazan dolomite and asmari lime, that its eastern part is pressed as an anticlinorium form but its western part as a syncline form. as a result of kerend fault practice most of the tectonically activities are seen in middle parts...

BACKGROUND The Hajar Mountains of Oman and the United Arab Emirates (UAE) is the highest mountain range in Eastern Arabia. As a result of their old geological origin, geographical isolation, complex topography and local climate, these mountains provide an important refuge for endemic and relict species of plants and animals with strong Indo-Iranian affinities. Among vertebrates, the rock climbi...
