studies of three selected sulfide-silicate assemblages from ore samples from the sar cheshmeh porphyry copper deposit led to some ore genetic conclusions. the presence of chalcopyrite blebs in the groundmass orthoclase and quartz from the stock suggests liquid immiscibility in a cooling late-magmatic melt. this is in favor of the orthomagmatic model proposed for porphyry copper deposits. the pr...

Monitoring the water contaminants is of utmost importance in resource management. Prediction total dissolved solid (TDS) particularly essential for quality management and planning areas exposed to a mixture pollutants. TDS primarily includes inorganic minerals organic matters, various salts increasing concentration causes esthetic problems. The reflection pollutant burden aquatic system can rem...

1. introduction the pattern has been the same for the planning and management of agriculture in rural areas, which is applied to various forms of state failure and inefficiency of the agricultural development programs. because this planning and management have not been designed based on needs, talents, and abilities of the rural areas, but based on consensus over the potential and actual needs ...

The effects of Range Management Plans (RMP) on soil and vegetationcharacteristics were studied in Eshtehard rangelands at Alborz province. The parameters ofyield, canopy cover, range condition and trend, bulk density, Organic Matter (OM%),Nitrogen (N), Phosphorous (P) and Potassium (K) were estimated on soil samples in sitesof Ghenzel Cheshmeh as RMP and sanctum of Rahmanyeh village. The data w...

Granted that literacy is a social practice involving different values, attitudes, feelings, and social relationships, this study attempts to examine literacy practices and the potential changes made through a history of forty years. The study was conducted in the village of Cheshmeh, near Mashhad, Iran, where the social definition of literacy emerged. The data have been collected through partic...

The recovery process of selenium from Iranian Sar-Cheshmeh copper anode slimes employing hydrometallurgical methods has been investigated. The copper anode slimes are made up of those components of  the anodes, which are not soluble in the electrolyte. They contain varying quantities of precious metals like gold, silver, selenium and tellurium. They are being extracted as a by product in th...
