List Minerals Associated with Gold

To know what type of rock is gold associated with you must see that the minerals most common in placer deposits are platinum, iridosmine, magnetite, iron pyrites, ilmenite, zircon, garnets, rutile and barytes; wolfram, scheelite, brookite and diamonds are less common. Diamonds are associated with gold in Brazil, and also occasionally in the Urals and in the United States. In auriferous quartz ...

Plutonic-Related Gold Deposits of Interior Alaska ...

Plutonk-relcttcd gold deposits in interior Alaska occur in the apexes of middle Cretaceous (mostly 93-86 Ma) reduced plutons and in spatially associated sedimentary and metamorphic rocks. Hydrothermal micas from these deposits have cooling ages 0 to 2 m.y. younger than those of magmatic micas and amphiboles from hosting intrusions.

1-5-2008· A review of studies on the trace element composition of native Au from various deposits shows that (1) a large number of trace elements have been detected in Au, (2) each deposit has its own suite of detectable elements, and (3) absolute concentrations of detected elements can vary considerably between deposits (e.g. McCandless et al., 1997, Outridge et al., 1998, Penny, 2001).

Our distinction of fluid end members based on trace elements is supported by data reported from other hydrothermal ore deposits. Fluid inclusion analyses from Bingham Canyon and other porphyry Cu-Mo-Au deposits confirm selective enrichment of B and As in magmatic vapor, in contrast to enrichment of Rb, Cs, and K in magmatic brines ( Fig. 3 ; Heinrich et al., 1999 ; Landtwing et al., 2010 ).

Iron oxide copper gold ore deposits - Wikipedia

Iron oxide copper-gold deposits are also often associated with other valuable trace elements such as uranium, bismuth and rare-earth metals, although these accessories are typically subordinate to copper and gold in economic terms. Some examples include the Olympic Dam, South Australia, and Candelaria, Chile, deposits.

1-7-2011· 3. The geochemical behavior of gold in hydrothermal systems. The occurrence of gold mainly depends on temperature, pressure, pH values, Cl − concentration, and fugacity of H 2 S in a hydrothermal system. Gold mostly occurs as AuCl − 2 in a system with temperature higher than 400 °C (Gammons and Williams-Jones, 1997), and with decreasing temperature being the primary mechanism causing gold ...

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 ...
