We report the iron (n = 13), copper sulfur 25) and lead 31) isotope compositions of mineralized samples from porphyry, skarn epithermal mineralization in Yenice region that lies east Biga Peninsula, Turkey. The vast majority isotopic data were analyzed world-class Arapuçandere Pb-Zn-Cu (Ag-Au) deposit is one best example intermediate sulfidation deposits within Serbo-Macedonian-Rhodope metallog...

The Lapeh-Zanak copper deposit is located about 15 km east of Tehran, in the southern part of the Central Alborz Zone. The rock units exposed in this area include a sequence of volcanic and pyroclastic rocks (basalt, andesite, trachy-andesite and dacitic and vitric tuff) belonging to the Fajan Formation with the Paleocene-Lower Eocene age, which are cut by subvolcanic igneous masses with a comp...

Large albitite bodies associated with explosive brecciation, fenite aureoles, intrusive carbonate rocks, olivine dolerites, and copper mineralization are described from the Dead Sea rift region in the south-eastern Sinai Peninsula. The main carbonate phases comprise breunnerite and dolomite with actinolite the main phase in the fenites. Field and isotopic evidence indicates that the intrusive c...

Abstract Porphyry Mo deposits are important suppliers of molybdenum for industrial applications, but the origin and source metals in these remain debated. Here, we present isotope data Miocene mineralized porphyritic monzogranites (MPMs) Paleocene barren biotite tuffs (BMTs) from Bangpu porphyry (Cu) deposit Gangdese metallogenic belt. The results show that MPMs display radiogenic Sr Pb isotope...

The Bozjani copper deposit is located about 30 km west of Fariman city, Khorasan Razavi Province. Host rocks to mineralization are mostly pridotites and basalts of Fariman ophiolitic sequence. Ore body consists of two parts: lower and upper. Lower part has formed a stringer of primary sulfides as stockwork, veinlets, and disseminated. Uppermost part has lenticular shaped dominated by ribbon-lik...

The Pb-Zn-Cu deposit of Ulldemolins occurs within the Carboniferous sedimentary series of the southernmost Catalonian Coastal Ranges. It consists of sulphide-bearing calc-silicate assemblages, with epidote, Ca-amphiboles and Ca-garnet, which develop selectively along a dolomicrite bed near the contact with a granite porphyry. Two mineralisation styles can be differentiated: a) banded and b) irr...

Copper, obtained from porphyry deposits formed in arc settings, is a critical resource, and primarily sourced magmas. However, the processes that shape copper contents of magmas are up for debate. Existing models place emphasis on different petrological agents explain large-scale trends systematics. Previous studies have noted ’Cu paradox,’ where with high Sr/Y ratios, indicative ore-forming po...

The Sorkheh deposit in northwestern Iran exhibits several readily visible general characteristics of sediment-hosted stratiform copper (SSC) mineralization. It consists of fine-grained disseminated base-metal sulfides within gray sandstones (gray beds, the basal whitish Miocene sandstone and shallow-water) that overlie a thick sequence of red beds (Miocene Upper Red Formation). The host gray be...

The purpose of mineral exploration is to find ore deposits. The main aim of this work is to use the fuzzy inference system to integrate the exploration layers including the geological, remote sensing, geochemical, and magnetic data. The studied area was the porphyry copper deposit of the Kahang area in the preliminary stage of exploration. Overlaying of rock units and tectonic layers were used ...
