In order to explore probable blind mineralized zones of the Aliabad deposit, it is necessary to evaluate the element concentrations towards depth or margins of the deposit. Modelling primary geochemical haloes could be useful in this stage. Ore bodies at the Aliabad deposit are primarily controlled by structural features, which provide an opportunity to investigate the zonality in primary halos...
The fifth Bahram one of the Sassanid kings has attracted the attention of historians, writers and researchers from many aspects in Iranian poetry and prose works. One of the striking issues about the fifth Bahram is his nickname; Most of the sources referred to him as Bahram Gour. Although, historical and literary narratives are Narrateed the title of guor for Bahram, itchr(chr(chr('39')39chr('...
The Kuh-Sorbi barite-Pb ± Cu deposit, which is located southeast of Mashhad in Khorasan Razavi Province of Iran, occurs as vein, open space filling, host rock replacement, and cement within the fault breccia in the Upper Triassic Nayband Formation metamorphosed carbonate rock unit. This deposit contains of barite (80–85%) and galena (10–15%), with small amounts of chalcopyrite and quartz. Barit...
The RoudMajan kaolin deposit is located about 35 km northwest of Torbat-e- Heydarieh city, Khorasan Razavi Province, in the Great Kavir Block subzone. Field evidence and laboratories results indicate that this deposit is genetically associated with the alteration of basaltic andesite rocks (Lower Eocene). According to the microscopic evidence and various analytical techniques (XRD, SEM-EDS, FE-...
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 ...
the effect of an electroless ni-cu-p coating on the fatigue behavior of quenched and tempered ck45 steel has been investigated. the fatigue tests under rotating bending conditions have been conducted in three different conditions of uncoated, as-deposited and shot peened prior to the coating deposition. the results indicate that plating of the base steel leads to a fatigue life reduction. the d...
Trace metals in the aquatic environment are generally concentrated o n solid geochemical phases which eventually become incorporated into estuarin e and marine sediments . The mechanism of trace metal concentration is believe d to be adsorption with various geochemical phases such as hydrous metal oxides , clays, and organic matter . Metals in estuarine or marine sediments can thu s be expected...
principal skarn deposits along the northern margin of the ahar batholith from west to east include mazraeh, vine and gowdoul skarn deposits. among these skarn deposits, the mazraeh cu-fe skarn deposit is the most typical skarn deposit in the nw iran. this skarn deposit is located 5 km. north of mazraeh village and 20 km north of ahar town. the origin and development of the skarn can be related ...
introduction the senj deposit has significant potential for different types of mineralization, particularly porphyry-like cu deposits, associated with subduction-related eocene–oligocene calc-alkaline porphyritic volcano-plutonic rocks. the study of fluid inclusions in hydrothermal ore deposits aims to identify and characterize the pressure, temperature, volume and fluid composition, (ptx) cond...
