The geochemical and isotopic (strontium, boron, radium, oxygen, hydrogen) variations of geothermal waters from five different regions in Morocco were investigated in order to evaluate the sources of solutes and the mechanisms of water-rock interaction. During 2008 to 2010, twenty-two geothermal water samples were collected from the southern, central, and northern parts of Morocco. The water sam...
Pyritic shale horizons of the Newland Formation (Belt Series, Mid-Proterozoic) show striking similarities to Proterozoic pyritic shales elsewhere that are host to major lead-zinc deposits, such as Mt. Isa and McArthur River. However, in contrast to these deposits the pyritic shales of the Newland Formation contain only minute quantities of lead and zinc. Elevated concentrations of lead and zinc...
Gazu copper deposit is located in the boundary of Tabas and Lut block, 65km southeast of Tabas and 15km southwest of Deyhouk. The dominant lithology in the area consists of Shotori dolomite and limestone and Shemshak shale and sandstone. Intrusive rocks with intermediate composition are widespread and numerous in the area. They consist of diorite, monzonite, and quartz monzonite to granite. Mi...
Antimony mineralization occured in Hamedan district (Faghireh) which is related to Alvand Granitoids. The mineralization occurcd as a series of veins. Thickness of veins are variable and reach up to 0.7m. The veins are emplaced along high angle faults. These faults acted as a pathway for migration of are nuids. Veins are composed of stibnite, pyrite, realgar and orpiment with quartz as a g...
Mineralization along continental suture zones is facilitated through the frequent presence of pathways from fertile mantle source regions to crustal repositories. Due their inherent rheological weakness, these are often concealed, which hinders surface-based observations. Here, we use zircon U-Pb and sericite 40Ar/39Ar dating, whole-rock geochemical data, investigate crystallization mineralizat...
The article presents the results of study Ilmeno-Vishnevogorsky and Buldym carbonatite complexes in Urals. It has been established that carbonatites complex are represented by high-temperature calciocarbonatites (sövites I II) with pyrochlore ore mineralization. U-Ta-rich populations uranium pyrochlores (I) fluorocalciopyrochlores (II) crystallize miaskite-pegmatites sövites I; (III) Sr-REE-pyr...
In this study, we have compiled new and existing mineralogical geochemical data on Fe-Mn mineralization from the Aegean region [Attica (Grammatiko, Legrena, Varnavas), Evia Milos islands], aiming to provide insights genesis of in that its potential environmental implications. A common feature those deposits is relatively low Cr, Co, V, Ni, Mo, Cd content, whereas Ba, As, W, Cu, Pb, Zn show rema...
Exploratory Geochemical Studies to Determine the Mineralization Zones Around the Zarshuran Gold Mine
The method of weights of evidence is one of the most important data driven methods for mineral potential mapping in GIS. In this method, considering the characteristics of known mineralized locations, we can prospect new mineralized areas. In this research work, the method of weights of evidence has been used for hydrothermal gold potential mapping in Torbat-e-Heydarieh area, east of Iran. As a...
