Yeylagh-e-Gharechi porphyry copper deposit is located in the Arasbaran metallogenic belt at northwestern Iran, 25 kilometer of Ahar. Porphyry mineralization at the Yeylagh-e-Gharechi deposit occurred in post-Oligocene quartz monzonite and monzonite bodies which was hosted by Eocene volcanic rocks. Mineralization occurred as veins, veinlets and dissemination in hypogene zone. Supergene zone has ...

Arasbaran is one of the most important protected regions in Iran located in NW of the country and east of E Azarbaijan Province. Several reports have been published on the mycobiota of this region however there is only few records about rust fungi of Arasbaran. Our research on rust fungi of Arasbaran region get started since 2006. During this study, several rust taxa collected and identified fr...

In this paper, nine species of bolete fungi belonging to genera Boletus, Leccinum, Suillus and Xerocomus are reported from Arasbaran (E. Azarbaijan Province, N.W. Iran).From identified species Boletus edulis, B. erythropus, B. fechtneri, B. fragrans and X. ferrugineus are reported from Arasbaran as new for Iran.B. pulverulentus, L. pseudoscabrum, S. collinitus and S. granulatus have already bee...

Due to the importance of the Arasbaran forest (E. Azarbaijan, N.W. Iran) as a biosphere preserve and having a rich flora and fauna, macrofungi flora of Arasbaran region, were studied from 2003. This is the first in a series of publications on floristic studies of macrofungi of Arasbaran forests. In this paper, species of the genus Cortinarius, subgenus Myxacium are studied.The genus Cortinarius...

Ecological Role of Altitude on Quantitative Characteristics Caucasian Oak (Quercus macranthera Fisch. & C.A.Mey. ex Hohen.) Stands in Arasbaran Forest

Ecological Relationships of Slope and Elevation with Rowan (Sorbus aucuparia L.) in Arasbaran Forests

This article proposes a new formulation for the maximum leaf spanning tree problem (MLSTP) using network flow concepts to ensure graph connectivity of problem’s solutions. Since MLSTP is NP hard, genetic algorithm (MGA) also developed solve large-scale instances. The proposed optimally solved 37 out 41 instances existing benchmarks, comparable with results available formulations in literature. ...

this research has been carried out with the aim of the determination of the land-use changes of the forests in the protected area of arasbaran. the determination of the changing points and the factors influencing these changes by the use of gis and remote sensing are the main aims of this research. accordingly, the satellite pictures pertaining to the years 1987 and 2005 along with other necess...

The essential oils of the aerial parts of A. armeniaca and A. incana, collected from Arasbaran area (East Azarbaijan province, Iran) were extracted by hydrodistillation and analyzed by GC-MS. In total, 16 and 40 constituents were identified and quantified in the oils of A. armeniaca and A. incana representing 80.5% and 84.6% of the oils, respectively. The essential oil of A. armeniaca was mainl...
