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...

The Tethyan Himalaya is the fourth metallogenic belt discovered to date within Tibetan Plateau and contains chromite, gold Sb–polymetallic mineralization. records a series of complex tectonic–magmatic events that include break-up, subduction, collision, detachment, obduction Eastern Gondwana continent, all which generated ideal conditions for ore formation. However, this area remains under-expl...

Abstract Many porphyry molybdenum deposits are hosted in multi-phase plutons, but it is unclear some how these magmas originated and whether the pluton intruded as fractionated or was by new batches of magma. New mapping has clarified field relationships between units White Pine Mo system Little Cottonwood stock, Utah (western United States), including intrusion, Red porphyry, rhyolite dikes, p...

gomish-tappeh zn-pb-cu (ag) deposit is located 90 km southwest of zanjan, in northwestern part of urumieh-dokhtar volcano-plutonic zone. exposed rocks at the area include oligo-miocene volcano-sedimentary and sedimentary sequences as well as pliocene volcano-plutonic sequence (andesite porphyry dykes, dacitic subvolcanic dome and rhyodacitic volcanics). alteration in the deposit developed as si...

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 ...
