Zavarian epitermal gold (copper) deposit is located in an intracontinental volcanic cone (stratovolcano) with the Early Miocene age, in the middle of the Urmia-Dokhtar magmatic arc. The host rocks of this mineralization include a set of basaltic, andesitic-basaltic, andesitic, dacitic, as well as granodiorite and tonal units that have been exposed in volcanic form (lava and pyroclastic) and sem...

Firouzkuh prospect area is located about 35 km northeast of Torbat-e- Jam, Khorasan Razavi Province. Geology of the area includes metamorphosed rocks of Miankouhi Formation, which has intruded by monzogranitic to dioritic intrusions. The magnetic susceptibility of the intrusive rocks varies from 0 to 43 ´ 10-5 SI and they belong to reduced granitoids of ilmenite series. These rocks are affected...

Shelgerd area is located south of Mashhad, N.E of Iran, within Binalud Structural Zone. This region is affected by regional metamorphism, slate and phylite are the main metamorphic rocks of the area. Teriassic slate, phyllite, sandstone and Jurassic conglomerates crop out parallel to Sang bast- Shandize fault. Mineralization occurred as vein type, with trend of N65E to N50W with 75 degrees to t...

25 26 The Tropicana gold deposit is located adjacent to the margin of the Yilgarn craton in 27 the Albany–Fraser orogen, Western Australia. The deposit is hosted in granulite facies 28 quartzo-feldspathic gneisses of the Archean Tropicana Gneiss. Ore bodies comprise 29 biotite-pyrite alteration concentrated in shear zones that formed during NE-SW 30 shortening in the late Archean, and clearly p...

Ulug-Sair Au-Bi-Te-Se mineralization is one prospect for native Au in the Western Tuva, and its origin remains debated. Mineralization consists of gold–sulfide–quartz veins host sedimentary rocks (conglomerates, siltstones, shales), quartz–tourmaline, quartz–carbonate–sericite–altered rocks. To determine origin, we examined mineralogical–geochemical features, formation conditions, fluid sources...

Geological and geochemical studies of gold mineralization in Bode-Saadu axis, Southwestern Basement Complex, Nigeria have been conducted order to study their mode occurrence, structural settings, pattern distribution potential. reveal that granite gneiss are the prominent rocks area exist north-eastern, north-western southwestern part whereas mica amphibole schist occur as low-lying exposure. P...
