biogeochemistry is a useful tool for assessing geochemical dispersion patterns. sari gunay epithermal gold deposit was selected in order to assess the application of biogeochemical exploration for gold in northwestern iran. in this study, four sites were sampled in a profile perpendicular to mineralized vein with a control site two km far-off mineralized vein. a sample from each dominant plant ...

The Tareek Darreh gold deposit is located 40km north of Torbat-e Jaam in the Khorassan-Razavi province, NE-Iran. The study area mainly comprises slightly metamorphosed, sedimentary rocks of Jurassic age including alternation of shale, siltstone, and sandstone. These rocks have been intruded by plutonic rocks such as gabbro-norite, diorite, quartz-diorite, and rhyodacite. The ore bodes are expos...

The purpose of the present study is to evaluate mass fractions group noble metals (gold, silver, platinum, ruthenium, osmium, palladium, iridium, rhodium) in ores and host rocks Pioneer deposit (the Upper Amur Region, Russia) determine their migration activity hydrochemical classification ore by sizes. object primary oxidized ores, as well hosting this mineralization. employs method quantitativ...

introduction pyrite is the most abundant sulfide mineral in low sulfidation ore deposits. experimental studies have shown that low-temperature ( 200°c) from hydrothermal or metamorphic fluids (butler and rickard, 2000). framboidal pyrite mostly occurs in sedimentary environments, though it could also form during metamorphism and hydrothermal alteration (scott et al., 2009). the pyrite formed te...

Gold mineralisation is the result of physico-chemical and thermal processes of the earth’s interior. We may view a geological process of gold mineralization as a stochastic process Z(x): xD, where D may be considered as a mineral deposit. In the case of gold mineralization, samples drawn at regular intervals may be considered as following a discrete stochastic process. The point of interest is...

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...
