The Sungun Cu-Mo porphyry deposit forms part of the Ahar–Arasbaran Magmatic Belt (AAMB). Its host Miocene stock is quartz monzonitic in composition and cut by intermediate dykes that post-date mineralization. These contain pyroxene enclaves ambiguous origin. Dykes microdiorite are observed within diorite dykes, whereas later three different kinds (diorite, hornfels) sizes between 1 10 cm. Encla...

jian cu deposit is hosted by surian volcano-sedimentary complex of permo-triassic age on the eastern edge of the sanandaj-sirjan metamorphic zone at a distance of 195 km from shiraz, southwestern iran. the complex consists mainly of metabasalt, chlorite-quartz schist, chlorite-muscovite schist, mica schist and graphite schist. pyrite is the most important sulfide and chalcopyrite is the major c...

Increases in the magnitude of positive Ce anomalies zircons from igneous rocks are often interpreted to be controlled by progressive melt oxidation and have been used provide evidence for elevated redox state magmas associated with porphyry Cu deposits. In this paper, we test idea comparing trace element compositions Resolution Cu-Mo deposit, Arizona, numerical models systematics zircon-melt pa...

Abstract Chemical exchange between silicate magmas and carbonate rocks has major implications for igneous fractionation, atmospheric CO2 flux, formation of mineral deposits. However, this process is only partly understood, long-standing questions whether, where, how can be digested by melts remain controversial. We describe evidence pervasive chemical melt rock in a shallow porphyry setting dri...

The Northparkes district, central New South Wales, hosts several economic Cu–Au deposits associated with discrete, thin, porphyry intrusive complexes emplaced in the Late Ordovician during formation of Macquarie Arc. recently discovered Two-Thirty Cu–Au–(Mo) prospect is a mineralised magmatic–hydrothermal breccia complex that hosted by moderately east-dipping Goonumbla Volcanic Complex on weste...

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...

This work presents the application of a geostatistical-based modeling approach for building up electrical properties acquired from a geophysical electrical tomography survey deployed for the purpose of porphyry Cu exploration at the Takht-e-Gonbad deposit, in the central domain of Iran. Electrical data were inverted in 2D along several profiles across the main favorable zones of Cu-bearing mine...
