Footprints of Fe-oxide(-Cu-Au) systems

چکیده
Recognizing footprints of Fe-oxide(-Cu-Au) ("IOCG") mineralization depends on the perspective that the beholder has on the nature and origin of these deposits. This follows from the fact that no simple descriptive model can adequately capture the diversity of the systems that are included in this family (any more than for epithermal deposits or similar broad classes). Nor, is there any semblance of a consensus on the mode(s) of origin. Hence application of the footprint concept depends on working with a number of descriptive and genetic models. This discussion touches on features common to most descriptions of IOCG and related systems, a range of possible origins, and the implications of this range for recognizing such systems.

Qaleh-Zari is a Fe-oxide Cu-Ag-Au vein type deposit located 180 km south of Birjand, in eastern Iran. Host rocks are mainly Tertiary calc-alkaline to K-rich calc-alkaline with transition to shoshonitic andesite and andesitic basalts, but in the central part shale and sandstone of Jurassic age. Andesitic rocks from the western region of Qaleh-Zari were dated to 40.5 ± 2 Ma. Four trends of faults...

Modeling based on equilibrium thermodynamic and physicochemical condition suggests that Bi-rich melts can efficiently scavenge Au from hydrothermal fluids, even if these fluids are highly undersaturated with respect to Au minerals. At this study the Kuh-e Dom prospecting area in northeastern of Ardestan city (northern part of Anarak metallogenic province) as the prominent sample of Iron Oxide C...

The spin-polarized calculations in generalized gradient approximation density–functional theory (GGA–DFT) have been used to show how the existence of second metals can modify the atomic hydrogen adsorption on Au (100), Cu (100), and Pt (100) surfaces. The computed adsorption energies for the atomic hydrogen adsorbed at the surface coverage of 0.125 ML (monolayer) for the monometallic Au (100), ...

The Qaleh-Zari specularite- rich Cu-Au-Ag deposit is located 180 Km south of Birjand. Host rocks are mainly Tertiary andesites and andesitic basalts and some Jurassic shales and sandstones. Andesitic rocks from the western region of Qaleh-Zari were dated to 40.5±2 Ma. Four trends of faults and joints are identified in the mine area. The oldest is mineralized. Three major sub-parallel quartz ve...
متن کاملMethanol Steam Reforming Catalyzing over Cu/Zn/Fe Mixed Oxide Catalysts
Methanol steam reforming plays a pivotal role to produce hydrogen for fuel cell systems in a low temperature range. To accomplish higher methanol conversion and lower CO production, the reaction was catalyzed by CuZnFe mixed oxides. Various ratios of Fe and Cu/Zn were coprecipitated in differential method to optimize the CuZnFe structure. The sample containing 45Cu50Zn5Fe (Wt. %) revealed its m...
