Magnetotelluric (MT) imaging results from mineral provinces in Australia and the United States show an apparent spatial relationship between crustal-scale electrical conductivity anomalies major magmatic-hydrothermal iron oxide-apatite/iron oxide-copper-gold (IOA-IOCG) deposits. Although these observations have driven substantial interest use of MT data to image ancient fluid pathways, exact ca...

in this study, the reliability of the primary gold mineralization exploration using multispectral etm+ imagery was investigated in lahroud region, northwest iran, which was conducted by integration of alteration and structural indicators. co-occurrence of the clay minerals and iron oxides is an important criterion in gold deposit exploration; therefore, their alteration zones were mapped using ...

kuh- e -zar gold deposit located 35 km west of torbat-e-heydaryeh, (khorassan e- razavi province), east of iran. this deposit is a specularite-rich iron oxide type (iocg). this mine is situated within khaf-bardascan volcanic plutonic belt. based on recent exploration along this belt, several iocg type system plus kuh-e-zar deposit are discovered. in the study area, several type of tuff and lava...

groundwaters hydrochemistry of ayrakan and cheshmeh shotori areas and geochemistry of rare earth elements, indicate ayrakan alkali granite as the origin of uranium and other dissolved elements in groundwaters of these areas. geochemical and hydrogeochemical studies as well as the trend of uranium and thorium transition and mobility in aqueous environments of these areas indicate uranium adsorpt...

alteration of ophiolitic ultramafic rocks, formation of listwaenite and associated mineralization are interesting phenomena of metallogeny of khoy ophiolite. it seems that the hydrothermal circulations responsible for mercury mineralization were derived from geothermal systems caused by intermediate to acidic magmatism in neogene-pleistocene time. reactivation of brecciated serpentinite with hy...

Formulation of the problem. Modern advances in oceanographic studies sedimentogenesis and orogenesis open up opportunities for in-depth study rocks by fold-nappe systems, including Carpathian region. Review previous research. On territory Carpathians flysch complexes researchers have mainly noted findings carbonates manganese iron nodules.At same time, contain iron-manganese oxide mineralizatio...
