The main goal of this research work was to detect the different Cu mineralized zones in the Sungun porphyry deposit in NW Iran using the Spectrum-Volume (S-V) fractal modeling based on the sub-surface data for this deposit. This operation was carried out on an estimated Cu block model based on a Fast Fourier Transformation (FFT) using the C++ and MATLAB programing. The S-V log-log plot was gene...

کانی فیروزه (turquiose) که با فرمول cual6(po4)4(oh)8.4h2o شناخته می شود، جزء کهن ترین کانیهای گرانبها محسوب می شود. شهربابک از جمله مناطقی است در ایران که نمونه های بسیار زیبا و متنوع فیروزه در آن یافت می شود. کانسار مس پورفیری میدوک در شمال شرق شهر بابک در استان کرمان واقع شده است. سنگ میزبان این کانسار سنگ های آتشفشانی و آذرآواری ائوسن می باشد که توسط توده های نفوذی متعددی از جنس گرانودیوریت ...
The Maherabad gold-rich porphyry copper prospect area is located in the eastern part of Lut block, east of Iran. This is the first porphyry Cu-Au prospecting area which is discovered in eastern Iran. Fifteen mineralization-related intrusive rocks range (Middle Eocene 39 Ma) in composition from diorite to monzonite have been distinguished. Monzonitic porphyries had major role in Cu-Au mineraliza...
Regional setting and geochronology of the Late Cretaceous Banatitic Magmatic and Metallogenetic Belt
Abstract The 1,500-km-long Banatitic Magmatic and Metallogenetic Belt (BMMB) of Romania, Serbia and Bulgaria is a complex calc-alkaline magmatic arc of Late Cretaceous age. It hosts a variety of magmatic-hydrothermal Cu, Au, Mo, Zn, Pb and Fe deposits, including Europe’s only world-class porphyry-copper deposits. Regional metallogeny can be linked to subduction of the Vardar Ocean during the La...
Airborne magnetic and radiometric datasets have, over the past few years, become powerful tools in identification of porphyry systems which may host economic copper–gold–molybdenum ore bodies. Magnetisation contrasts with unaltered rocks, coupled elevated signature, compared to rock, makes large-scale copper possible. Integrating these two different stream sediment data other geochemical explor...
The Grouh area is located about 19 km north-east of Sarduyeh city in Kerman Province. The major lithological units in this area include Eocene andesite and andesitic basalt. Oligo-Miocene intrusive units include diorite, quartz diorite and granodiorite; while pyroclastic units include tuff and breccia. The alteration in the Grouh area is remarkable due to the penetration of the intrusive masses...
