The leaves of Arum conophalloides (Araceae) were used in some west areas of Iran as a dessert. The aerial parts of the herb were collected from Sahneh Mountains, Kermanshah Province, West of Iran and was hydrodistilled by Klevenger-type apparatus. Composition of the essential oil was determined by GC and GC/MS. Totally, 18 components (92% of total essential oil) were identified. The oil contain...
Drought is one of the phenomena that has recently been identified as a major challenge , and has incurred a lot of damage in different parts of the world. The purpose of this study was to investigate and map drought in Kermanshah Province using the CZI index in ArcGIS for 1995-2016 using data from synoptic stations of Kermanshah, Kangavar, Sahneh, Harsin, Mahidshah, Sararood, Paveh, Ravansar, S...
There are three serpentine polymorphs (Lizardite, Chrysotile and Antigorite) in the serpentinites of ophiolitic mélange of south Sahneh. Lizardite is observed as flake structure in the matrix of peridotites while antigorite is overgrown on lizardite and chrisotile development is just restricted to the micro fractures as a development is restricted to the micro fractures as golden and transparen...
Ophiolitic complex of Sahneh could be considered as part of ophiolite sequences in the Zagros Suture Zone.This complex is a part of 3000 km belt, which is started from Syria after crossing south Turkey and Zagros leading to Oman. The studied ophiolitic complex is curvature in shape which is situated in south of Sahneh. No complete ophiolite sequence were seen in this complex. In general, t...
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...
Subduction initiation processes, such as those evidenced in the Izu-Bonin-Mariana (IBM) forearc crust are a key feature of modern-style plate tectonics. However, evidence for this process Precambrian is limited, due to scarcity ophiolite suites and particular lack typical complete ophiolitic sequences similar observed Phanerozoic ophiolites. Mineral analyses olivine, orthopyroxene, chrome spine...
Abstract In shallow-water limestones of the Plassen Formation in Tirolic nappe Northern Calcareous Alps, bauxite was formed on karstified and tilted platform margin grainstones to boundstones around ?Kimmeridgian/Tithonian boundary, or Early Tithonian as proven by Protopeneroplis striata Weynschenk, Labyrinthina mirabilis Salpingoporella pygmaea Gümbel. The established top obducted ophiolite st...
In order to determine morphological characteristics of Fusarium species associated with root and stem of maize in Kermanshah province, duringtwo growing seasons of 2006-2008, 110 samples, mostly from diseased plants were collected from different geographic regions of the province. The collecting localities were Gilan Gharb, Sarpol Zohab, Qasr Shirin, Sonqor, Kangavar, Bisotun, Ravansar, Kermans...
Two of this volume’s coeditors persuaded the third into commenting on his own paper. There are three clear alternatives as a “classic paper” on California terranes. In the first of these, Hamilton (1969) first mentioned the North American Cordillera as a collage of exotic terranes and argued that the continental margin of North America was built out from the shelf edge by material carried to it...
