The objective of this research is to determine all processes in the magmatic evolution and related hydrothermal activities that created the volcanic rocks and associated ore-forming systems of the Bafq ‎mining district. Several iron oxide-apatite (IOA) deposits were investigated in this area with a focus on the Sechahun ore deposit. The Bafq ‎mining district is well known for hosting significan...

The transport of fluid, heat ,and particles (bubbles and solid inclusions) in flowing molten steel is investigated in steel refining ladles, the continuous casting tundish, continuous casting mold and strand, and steel ingot casting processes. The two-equation k-ε model is used to simulate the turbulence. Multiphase fluid flow is numerically simulated with a Lagrangian-Eulerian approach, an Eul...

introduction the ahangaran pb-ag deposit is located in the hamedan province, west iran, 25 km southeast of the city of malayer . . the deposit lies in the strongly folded sanandaj-sirjan tectonic zone, in which the ore bodies occur as thin lenses and layers. the host rocks of the deposit are early cretaceous carbonates and sandstones that are unconformably underlain by jurassic rocks. ore miner...

Gardaneshir Pb–Zn deposit is hosted by dolomitic carbonates which is located in the SW Ardestan, central Iran. Ore body is stratabound type in this deposit. Primary ores in this type are composed of sphalerite, galena, barite and quartz with massive, banded, veined and disseminated structures. Evaluation of ore-grade at the Gardaneshir Pb-Zn deposit, based on chemical analysis which indicates a...

The distribution of organic species is explored using data acquired from a new dual quadrupole system that routinely measures eighteen gaseous species. The process of condensation and its affect on gas distribution is modeled, and a new discrimination diagram based on total gaseous species and the CO2/N2 ratio is introduced. We conclude that organic species concentrations indicate source; that ...
