Ore Deposit Types and Their Primary Expressions
Metals are largely derived from the mantle or crust by partial melting and fluid-related leaching. Ligands can be provided from the same sources, or from the atmosphere, hydrosphere and biosphere. Transport is mainly by mechanical or mass transfer mechanisms and by fluids. On and near the surface, biological processes can also concentrate and transport ore components or remove non-ore component...
متن کاملGeochemistry and mineralization of the East Ridge ore zone in Mehdiabad zinc-lead- barite deposit, Yazd Province, Central Iran
Mehdiabad zinc-lead-barite deposit is located in the Central Iran structural zone and about 116 km southeast of Yazd. The host rock of this deposit is Lower Cretaceous dolomitic limestone of the Taft Formation . The main ore minerals in the Mehdiabad East Ridge ore zone include hemimorphite, hydrozincite, cerussite, and chalcophanite. Ore textures are mainly replacement, brecciated, and open-sp...
متن کاملType of mineralization and studies of fluid inclusions of the Bolboli2 copper ore deposit, northeast of Sirjan, SE Iran
The Bolboli2 copper ore deposit is located about 110 km southwest of Kerman and lies in the Dehaj-Sarduieh metallogenic belt (Kerman Cenozoic Mamatic Arc, KCMA). This ore deposit is hosted by the Eocene extrusive igneous rocks (tuff, agglomerate, andesite, and dacite) and the Oligo-Miocene intrusive igneous body (granodiorite). These rocks are host the propylitic, phyllic, and silicic alteratio...
متن کاملThe Application of Artificial Neural Networks to Ore Reserve Estimation at Choghart Iron Ore Deposit
Geo-statistical methods for reserve estimation are difficult to use when stationary conditions are not satisfied. Artificial Neural Networks (ANNs) provide an alternative to geo-statistical techniques while considerably reducing the processing time required for development and application. In this paper the ANNs was applied to the Choghart iron ore deposit in Yazd province of Iran. Initially, a...
