principal skarn deposits along the northern margin of the ahar batholith from west to east include mazraeh, vine and gowdoul skarn deposits. among these skarn deposits, the mazraeh cu-fe skarn deposit is the most typical skarn deposit in the nw iran. this skarn deposit is located 5 km. north of mazraeh village and 20 km north of ahar town. the origin and development of the skarn can be related ...

Abstract Porphyry deposits are the main source for global Cu and Mo production. The generation of hydrous silicate magmas subsequent separation volatile-rich magmatic fluids with hydrothermal alteration significant processes leading to formation porphyry deposits. However, a specific understanding these has been limited by lack direct mineralogical records in evolving magmatic-hydrothermal syst...

Abstract Ore formation in porphyry Cu-Au-(Mo) systems involves the exsolution of metal-bearing fluids from magmas and transport metals magmatic-hydrothermal plumes that are subject to pressure fluctuations. Deposition ore minerals occurs as a result cooling decompression hydrothermal partly overlapping shells. In this study, we address role vapor-like through numerical simulations metal using G...

The copper ore in Chilean porphyry deposits is often associated with molybdenum minerals. This copper–molybdenum (Cu–Mo) sulfide generally mined from various locations the mining site; thus, mineral composition, oxidation degree, particle size, and grade vary. Therefore, operation, it common to blend ores spots then process them using flotation. In this study, floatability of five types Cu–Mo b...

Base metal mineralization at the Baal Gammon and Isabel deposits of Herberton Mineral Field (HMF) is hosted in metamorphosed greywacke beds Hodgkinson Formation, which were intruded by granite, porphyry dykes overlain volcanic rocks Kennedy Igneous Association during Carboniferous Permian. The tin deposit a silicified, chlorite-altered, quartz-feldspar (UNA Porphyry). polymetallic veins hosting...
