the late eocene-early oligocene sarnowsar granitic rocks and many dacitic to rhyolitic dykesintruded in metamorphosed and metasomatized shale, sandstone, calcite and dolomite marbles andvolcaniclastic and pyroclastic rocks. as a result several million tons of iron ores formed within carbonaterocks in the sangan area. the sarnowsar granitic rocks are mainly granite to granodiorite, metaluminous,...

objective: to find out the prevalence and relationship of anemia in reproductive age women in rural area of tabas, center of iran. iron deficiency anemia is the most common nutritional problem, affecting about 41.8% of pregnant and 30.2% of non-pregnant women worldwide. materials and methods: a cross-sectional study was conducted on the random sample of 382 reproductive age women in rural areas...

In this study, the isothermal reduction of iron oxide pellets, made of Iranian Chadormalo, Gole-gohar, and Sangan iron ores, was investigated in the temperature range of 900-1100°C. Tabas, Pabdana, Babnizoo, Karmozd, and Shahrood domestic coals were used as reductants. Parametric studies were performed and the effects of such factors as temperature, average particle size of iron ore and coal fi...

Abstract This paper presents organic geochemical evidence pointing to the occurrence of wildfire events at Triassic–Jurassic boundary in Central Iran. The studied outcrop section (the Kamarmacheh Kuh section) is comprised Upper Triassic Nayband Formation which passes conformably into Lower Jurassic Ab-e-Haji with no sharp boundary. Organic petrographical studies reveal a higher concentration se...

in an attempt to reconstruct the paleoenvironments of deposition for the middle jurassic baghamshah formation, samples collected from six outcrop sections along the shotori swell were subjected to detailed geochemical analyses. bulk geochemical and biological marker data indicate a logical trend of the variation of organic input, salinity, and oxicity within baghamshah paleoenvironments across ...
