Nodoushan clay deposit is located about 130km southwest of Yazd city in the Uromieh-Dokhtar volcano-plutonic belt. Based on the field, mineralogical and geochemical studies, the rocks of Nodoushan area are of volcanic type and are composed of dacite, andesite and olivine-basalt, the pyroclastic type (crystalline tuff), and the microgranodioritic intrusive rocks. According to Zr/TiO2 versus SiO2...
the relationship between topography, soil factors, and distribution of ecological vegetation groups in the nodoushan arid rangelands of yazd province (iran) was investigated. the present species were recorded in each vegetation group using a randomized-systematic sampling method. plant cover and density were estimated quantitatively using the transect and quadrate methods, and the two-way indic...
L2 learners’ individual differences are crucial factors that deserve attention in L2 education. Focusing on 2 main areas of individual differences (i.e., field (in)dependence and multiple intelligences), this study explored their relationships with L2 reading performance. Participants were 64 TEFL undergraduates and postgraduates. To assess the participats’ degree of field (in)dependence and mu...
Destructive mining operations are affecting large areas of natural ecosystems, especially in arid lands. The present study aims at investigating the impact iron mine exploitation on vegetation and soil Nodoushan (Yazd province, central Iran). Based dominant wind, topography, slope, area, parameters close to were recorded analyzed according distance from mine. To obtain cover, a transect plot wi...

Mineralogy and geochemistry of Nodoushan Zn-Pb deposit: A transitional deposit in UDMA, Central Iran
Eocene magmatism with intermediate-acid tuffs and volcanic rocks, the host to the Nodoushan deposit in Yazd province, intruded by Oligocene early diorite and later granite plutonic rocks. The former involved in iron skarn (containing epidote and euhedral grossularite) to the north and northern part of the deposit, the latter contributed to fault-controlled Zn-Pb deposit. The structural features...
The present study discusses a method used to produce updated information about vegetation cover in arid and semi-arid zones, using RS data and GIS technique. In this method, Landsat ETM+ data in 2002 was collected in an area of about 60000 ha in Nodoushan basin, Yazd, Iran. To collect the necessary ground data, 50 sites of different vegetation types were selected and the percentage of vegetatio...
To determine readiness of range for entry and exit livestock, achieving information such as vegetation characteristics, grazing behavior, soil moisture content and Environment temperature, is necessary. Therefore, in this study, the major plants phenological stages, Monthly temperature and precipitation data and Estimating soil moisture were investigated in the 4-year period (1386-1389). The st...
