Abstract Porphyry Cu ore deposits are a rare product of arc magmatism that often form spatiotemporal clusters in magmatic arcs. The petrogenetic evolution igneous rocks cover the temporal window prior to and during porphyry deposit formation may provide critical insights into processes key generating these systems. This study documents Palaeocene–Eocene Yarabamba Batholith, Southern Peru, was i...

Porphyry Cu and epithermal deposits are spatially and temporally related to specific volcanic and plutonic rocks emplaced during the formation of long-lived magmatic arcs formed along convergent plate boundaries (e.g., Sillitoe, 1972; Sutherland Brown, 1976; Titley, 1982; Sawkins, 1990; Bissig et al., 2003). Recognizing the presence, types of deposits, and age of the mineralized volcanoplutonic...

Abstract The Xiong’ershan district in central China hosts broadly coeval porphyry Au (Qiyugou deposit), Mo (Leimengou and barren (Huashan pluton) systems. key controls on the ore potential different mineralization styles these systems are not well understood, with first-order differences fluid chemistry melt sources being main alternatives. inclusion characteristics of all three have been studi...

eastern iran has great potential for porphyry copper deposits, as a result of its past subduction zone tectonic setting that lead to extensive alkaline to calc-alkaline magmatic activity in tertiary time. maherabad is the first porphyry cu-au prospecting area which is discovered in eastern iran. this is related to a succession o f monzonitic to dioritic porphyries stocks that were emplaced with...

Iranian Cenozoic magmatic belt, known as Urumieh-Dokhtar, is recognized as an important polymetallic mineralization which hosts porphyry, epithermal, and polymetallic skarn deposits. In this regard, multivariate analyses are generally used to extract significant anomalous geochemical signature of the mineral deposits. In this study, stepwise factor analysis, cluster analysis, and concentration–...

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 ...

Abstract Porphyry deposits are the main source for global Cu and Mo production. The generation of hydrous silicate magmas subsequent separation volatile-rich magmatic fluids with hydrothermal alteration significant processes leading to formation porphyry deposits. However, a specific understanding these has been limited by lack direct mineralogical records in evolving magmatic-hydrothermal syst...
