the takmeh-dash region comprises a wide variety of igneous bodies that have been developed from early to late neogen. the granitic rocks and related aplite apophyses have been developed along fault-dominated structures which defines a well pronounced mineralized zone. according to isotopic and fluid inclusion studies, most of the quartz-pyrite units are solution-related with some traces of cu, ...

isotopic and microthermometry results from sheikh-darabad cu-au indices in mianeh region, east-azarbaijan province, indicate cenozoic post-magmatic activities with developed adularia facies through an extended and neogene related alteration that is given rise to occurring silica vein systems as the main hosting locations for epithermal mineralization. the research evidence also has been coincid...

introduction a wide variety of world-class porphyry cu deposits occur in the urumieh-dohktar magmatic arc (udma) of iran.the arc is composed of calc-alkaline granitoid rocks, and the ore-hosting porphyry intrusions are dominantly granodiorite to quartz-monzonite (zarasvandi et al., 2015). it is believed that faults played an important role in the emplacement of intrusions and subsequentporphyry...

A large number of intermediate basic volcanic rocks and porphyry Cu-Mo deposits as well volcanic-hosted magnetite deposit have been recently discovered in the Xilekuduk area. However, no reports concerning petrogenesis age or their relationship with mineralization published to date. The purpose this study was make up for absence previous studies on Devonian activities area confirm between two s...

Abstract The Southern Permian basin in central Europe contains a number of important high-grade sediment-hosted Cu deposits. Laterally extensive stratabound and Zn-Pb sulfide mineralized rocks are located at major stratigraphic redox boundary, where coarse-grained continental sandstones the uppermost Rotliegend Group overlain by carbonaceous mudstones (T1) limestones (Ca1) Zechstein Formation. ...

In this study, we have processed the spectral bands of airborne hyperspectral data Advanced Visible Infrared Imaging Spectrometer-Next Generation (AVIRIS-NG) for delineating surface signatures associated with base metal mineralization in Pur-Banera area Bhilwara district, Rajasthan, India.The primaryhost rocks Cu, Pb, Zn are Banded Magnetite Quartzite (BMQ), unclassified calcareous silicates, a...

The Lower Yangtze River Belt (LYRB) is a well-known and important base area with regard to Cu polymetallic resources in China. Large deposits the LYRB are strongly associated Cretaceous adakitic rocks. However, petrogenesis of Early adakites temporal–genetic relationship mineralization still disputable. Dongguashan (DGS) deposit Tongling ore cluster one largest LYRB. DGS intrusion mainly compri...

The Hirvilavanmaa (Au-only) and Naakenavaara (Cu-Co-Au-Ni) deposits, located only 5 km apart in the Paleoproterozoic Central Lapland belt (CLB) northern Finland, represent two types of orogenic gold mineralization that dominate CLB: (1) Au-only (2) Au with atypical metal association, respectively. In this study, we compare these deposits order to pinpoint origin differences their associations. ...

The trace element composition of detrital magnetite grains recovered from six local streams around the Casino high-grade porphyry Cu-Au-Mo deposit, west-central Yukon, is compared with igneous and magmatic-hydrothermal mineralized unmineralized host rocks at deposit. Linear discriminant analysis 12 elements (Mg, Al, Ti, V, Mn, Co, Cr, Ni, Cu, Zn, Ga Ge) plots Ti versus Ni/Cr are used to discrim...

the darreh-zar porphyry copper deposit, located in the urumieh – dokhtar magmatic belt, lies about 10 km southeast of sar-cheshmeh porphyry copper deposit. the ore body with hydrothermally altered zones including potassic, chlorite-sericite, sericite, argillic and propylitic all related to the darreh-zar porphyry stock intruded the eocene volcanic rocks. pyrite, chalcopyrite, molybdenite, with ...
