different types of iron oxides deposits have been identified along the khaf – dorouneh volcanic and plutonic belt in north east of iran. kuh-e-zar is one of these ore deposits known as fe- oxide gold deposit. the main purpose of this paper is to detect and discriminate the iron oxide minerals in this area based on the etm+ data. data processing has been done by envi (environment for visualizing...

sorkheh-dizaj apatite-iron oxide deposit is located 32 km southeast of zanjan. the area is situated within the tarom subzone of western alborz-azarbaijan structural zone. the oldest units at the sorkheh-dizaj area are eocene trachyte, trachyandesite, olivine basalt and volcanoclastic brecciate tuff and lapilli tuff which intruded by a quartz-monzonite, monzonite and granite subvolcanic pluton o...

Polyphenols from green tea were used to electrolessly deposit gold on silk cocoons (SCs) and nanoporous aluminum oxide (AAO) templates. The gold coated cocoons were used as electrodes in supercapacitors and showed a capacitance as high as 254 F g(-1) and a specific power of 2287 W kg(-1). A metal coated AAO template was used for molecular separation.

The Jagpura Au-Cu deposit is situated within the Aravalli craton in northwestern part of India. In present work, petrography, mineral chemistry, fluid inclusion and sulfur isotopic compositions were used to study deposit. ore association arsenopyrite, loellingite, chalcopyrite, pyrrhotite pyrite, along with native gold, magnetite apatite. gold fineness ranges from 914–937‰ (avg. 927‰). presence...

barika gold (and silver) rich massive sulfide deposit is located 18 km east of sardasht, north western part of sanandaj-sirjan metamorphic zone. rock units outcropped in this area are cretaceous metamorphosed volcano-sedimentary rocks in green schist facies, and include association of meta-andesite, meta-tuffite, phyllite and slate rocks, where the meta-andesitic unit (kmv1) is host rock to the...
