copper ore and its tectonic setting

Porphyr Copper • GeoLearning • Department of Earth Sciences

Tectonic setting of porphyry copper and epithermal ore deposits. Porphyry copper, skarn and epithermal ore deposits are the most common type of hydrothermal ore deposits. They are genetically linked to convergent tectonic margins characterized by calcalkaline magmatism.

Temporal–spatial distribution and tectonic setting of

Oct 01, 2015· 1. Introduction. Porphyry copper systems are mainly developed at convergent plate margins, including continental margin and island-arc settings (Sillitoe, 2010, and references therein), where subduction of oceanic crust is related to arc-type magmatism that generates most of the hydrous, oxidized upper crustal granitoids genetically related to ores.. In these magmatic arcs, deformation can

Porphyry copper deposit Wikipedia

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. In later stages, circulating meteoric fluids may interact with the magmatic

Metal source and tectonic setting of iron oxide-copper

Mar 01, 2017· The tectonic setting of IOCG mineralisation is such that Mesozoic and Cainozoic examples occur dominantly in ocean-facing continental arc settings (the Andes; Groves et al., 2010), whilst those in the older geological record are dominantly in collisional and post-orogenic settings. This strongly indicates that the history of mineralisation for

Tectonic setting of the pebble and other copper-gold

The Pebble Cu-Au-Mo deposit in southwestern Alaska, containing the largest gold resource of any known porphyry in the world, developed in a tectonic setting significantly different from that of the present-day. It is one of a series of metalliferous middle Cretaceous porphyritic granodiorite, quartz monzonite, and diorite bodies, evolved from lower crust and metasomatized lithospheric mantle

Copper extraction Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).

Porphyry Copper Deposits Geology for Investors

Oct 17, 2019· The only reason these ore bodies are economic is because porphyries are huge, with hundreds of millions of tonnes available in a fairly low-cost mining setting. Many porphyry copper mines have significant economic amounts of secondary minerals including gold (usually called a gold copper porphyry), molybdenite (in the south-western USA), and
