Copper is soft but tough. It is easily mixed with other metals to form alloys such as bronze and brass. Bronze is an alloy of tin and copper and brass is an alloy of zinc and copper. Copper and brass are The Quellaveco porphyry Cu–Mo deposit (Fig. 2) is one of the world’s largest unexploited copper resources with ore reserves of 1.3 billion tonnes at 0.57% Cu (Anglo American, Annual Report 2019). At least six intrusive porphyry phases have been identified at the deposit which form stock and dyke complexes (Fig. 2 ) emplaced over ~ From long-lived batholith construction to giant porphyry copper

Using zircon trace element composition to assess porphyry copper
The Late Triassic Guichon Creek batholith is a large (~ 1800 km2), composite, zoned batholith that hosts several large porphyry Cu-Mo deposits of the Highland Valley Copper district. The batholith consists of intrusive rocks that range in composition from gabbro to quartz monzonite. Adjacent to the mafic margin of the Porphyry copper deposits are copper ore bodies that are formed from hydrothermal fluids that originate from a voluminous magma chamber several kilometers below the deposit itself. Predating or associated with those fluids are vertical dikes of porphyritic intrusive rocks from which this deposit type derives its name.Porphyry copper deposit

Geology and origin of the Zhunuo porphyry copper deposit
Zhunuo is a porphyry deposit in the western GPCB. It was discovered in 2004 by the No. 2 Geology Survey Team of Tibet, China. Zhunuo contains 2.3 Mt copper metals at an average grade of 0.57% (Sun et al. 2018).Previous studies have reported zircon U-Pb ages, geochemistry of igneous rocks and molybdenite Re-Os ages for the Abstract. Porphyry Cu systems host some of the most widely distributed mineralization types at convergent plate boundaries, including porphyry deposits centered on intrusions; skarn, carbonate-replacement, and sediment-hosted Au deposits in increasingly peripheral locations; and superjacent high- and intermediate-sulfidation Porphyry Copper Systems1 Economic Geology GeoScienceWorld

A new model for the optimal structural context for giant porphyry
We tested this hypothesis through an integration of all the relevant data available from the main Andean porphyry copper deposits. This region was selected because it constitutes by far the largest known Cu concentration in the planet (985 Mt of Cu; Sillitoe, 2012) and individual deposits of the belts include the largest known Popov K (2001) Porphyry copper–massive sulphide system in the Radka ore district (Bulgaria).

The importance of H2O in arc magmas for the formation of porphyry
Post-collisional porphyry copper deposit (PCD) is a new genetic type of PCDs discovered in the Himalayan–Tibetan orogenic belt. It is believed that the formation of ore-forming magmas results from the re-melting of a sulfide-bearing, thickened, juvenile mafic lower crust in a magmatic arc associated with the oceanic plate subduction.With ~109,000 Mt of ore, Chile owns 31 porphyry copper deposits ranging in size from 110 Mt to 21,300 Mt and averaging 0.2–1.3% copper, many of which also contain molybdenum, gold and silver (Table A1). 15 of the 31 porphyry copper deposits in Chile are currently being exploited and 7 of them belong to the 20 largest copper mines Copper and critical metals production from porphyry ores and E
