Kalchoyeh copper deposit is located about 110 km east of Isfahan, in Central Iran, Urumieh- Bazman volcanoplutonic belt. Host rocks of this deposit are Eocene volcanic rocks and tuffs which are pyroxene andesitic lava and sandy and lithic tuffs. Sandy tuffs are the main host rocks of the deposit. Ore mineralization is taken place as veins and veinlets and quartz is the main gangue mineral. Hypo...

The Shotorkhosb kaolin deposit is located about 7 km southeast of Torbat-e-Heydariyeh, Khorasan Razavi Province, northeast Iran. This deposit is a part of the Khaf-Kashmar-Bardaskan metallogenic zone. Field observations and laboratory studies indicate that this deposit is a product of alteration of Eocene andesitic rocks. In this study, different analytical techniques, such as XRD, SEM-EDS, FE...
The Tang Zagh iron deposit is located about 117 km Northeast of Bandar Abbas, Hormozgan Province in the structural folded-thrusted zone of the Zagros basin. Iron mineralization occurs in the form of iron oxides (hematite) within the salt dome and/or in fractures and between the layers of the younger strata with the Tertiary age. Based on the microscopic studies, dolomitic fragments of the host ...
The Baiyanghe uranium deposit is a currently important medium-sized deposit in the Xuemisitan area, Xinjiang. The hydrothermal alteration in this deposit is closely related to the uranium mineralization of the deposit. In this study, hyperspectral data are collected from drill cores in the Baiyanghe uranium deposit using a FieldSpec4 visible-shortwave infrared spectrometer to study the hydrothe...
The objective of this study was to test the combined effect of offstream water and trace mineral salt on cattle distribution in a riparian meadow and its adjacent uplands. From July 15 to August 26, 1996 and 1997, three treatments were each randomly assigned to one pasture in each of three blocks. Sixty cow/calf pairs were then randomly allotted to the grazed pastures. The treatments included 1...
کانسار مسگرماب در50 کیلومتری شمالشرق شهرستان قائن، در قالب برگه زمین شناسی 1:100.000 آبیز و زون شرقایران واقع شده است. سنگهای آتشفشانیکانسار مسگرماب به سن پالئوسن بالایی- ائوسن، شامل تناوبی ازگدازهها (آندزیت، تراکیآندریت، آندزیت-بازالت و بازالت) و موادآذرآواری (انواع توف وآگلومرا) هستند. این سنگها، بر اساس دادههای ژئوشیمیایی عناصر اصلی وکمیاب، شباهت زیادی بهگدازههای کالکآلکال...
