May 28, 2014· Porphyry Copper deposits play an important role in the global economy. These deposits provide over 60% of the world''s copper and include other important metals such as molybdenum, gold and silver. Porphyry copper deposits are known for their low grades and very high tonnage.

Porphyry System (religion, spiritualism, and occult) The Porphyry, or Porphyrian, system is one of the older systems of house division, obtained by evenly trisecting the ecliptic in each of the four quadrants. It was named after the neoplatonic philosopher Porphyry, who is said to have devised it.
Introduction PORPHYRY Cu systems are defined as large volumes (10−>100 km3) of hydrothermally altered rock centered on porphyry Cu stocks that may also contain skarn, carbonatereplacement, sedimenthosted, and high and intermediatesulfidation epi .
continuum of porphyry systems from CuAu, through AuCu, to the Aurich and Cupoor counterpart (Sillitoe, 1979; Sillitoe, 2000; Seedorff et al., 2005). Porphyry gold systems are not a very common type of gold deposit. Deposits assigned to this group include a few porphyries in the Chilean Maricunga belt
Porphyry Cu systems host some of the most widely distributed mineralization types at convergent plate boundaries, including porphyry deposits centered on intrusions; skarn, carbonatereplacement, and sedimenthosted Au deposits in increasingly
Copper, gold, and molybdenum are among the important minerals extracted from these deposits. For modeling purposes a simplified porphyry model was constructed based on known geologic information (Titley, 1982, and Pierce, 1995). An idealized porphyry copper system is shown in Figure
Porphyry and epithermal systems the state of play at end of 1960s (2) Ages of copper and gold belts and provinces poorly defined (isotopic dating in its infancy) Zoning patterns of hydrothermal alteration in porphyry and epithermal deposits poorly appreciated ; Porphyry gold and goldrich porphyry copper deposits undefined (notwithstanding Panguna)
Reconstruction of the porphyry systems suggests that goldbearing quartz stockworks were generated 600 to 1,000 m beneath porphyry mineralization in the Maricunga belt is closely comparable to that in the Philippines because of the association with dioritic to quartz dioritic porphyry stocks intruded into andesitic ...

1. Introduction. Porphyry copper deposits contain up to 100 t of gold and are among the largest reservoirs of gold in the upper crust (Kerrich et al., 2000).They are commonly surrounded by deposits and country rock containing gold that is thought to have been derived from them (Jones, 1992).Gold can be removed from porphyry copper systems by vapors that separate at high temperatures or by ...
Sep 25, 2019· The planned 1,600metre hole has been designed to test for gold and copper mineralization within a known porphyry intrusive body located in the footwall of the Veta Sur vein system .

Oct 26, 2017· This alteration zoning from propylitic to phyllic is typical of porphyry systems moving toward the typically mineralized core. Photo 1: C1724 980988 is the carbonatelatite porphyry contact, note the chaotic folding and brecciation. Photo 2: C1724 is a photo of the latite porphyry showing the phyllic alteration.
PDF | Analysis of 55 porphyry copper deposits demonstrates a continuum between porphyry coppergold deposits emplaced at a median depth of 1 km, with a median size of 160 million metric tons of ...
systems have allowed us to apply time to porphyry systems and better understand their staged evolution as well as the evolved hydrothermal fluids which participate in low sulphidation epithermal vein formation (figure 3). Porphyry AuCuMo Although porphyry AuCuMo deposits display considerable variation, some broad generalisations are possible.
The system is host to a spectacular and diverse range of rocks and alterationmineralization textures that facilitate a detailed understanding of its evolution, in particular the nature and controls of porphyryrelated propylitic alteration.
Porphyry deposits are one of the most important sources of copper and molybdenum, and are also major sources of silver, gold, and addition, porphyry deposits may host valuable byproducts ...
