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 CuMoAu 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 ).
Much gold has been found in iron pyrite as a contaminant, and ever rarer it is sometimes discovered a telluride where it is combined with the element tellurium. Many of the same minerals as found in sand can also be found in occurances of lode gold, but there are several other minerals that are just too soft to survive the rigors of weathering, they include . . .
Summary statistics for trace elements associated with selected CuAu skarn deposits are presented in tables 1 to 3. Ranges and means for elements (As, Cd, Se,
STATISTICAL STUDY OF SELECTED TRACE ELEMENTS WITH REFERENCE TO GEOLOGY AND GENESIS OF THE CARLIN GOLD DEPOSIT, NEVADA By MICHAEL HARRIS and ARTHUR S. RADTKE ABSTRACT Linear regression and discriminant analyses techniques were I applied to gold, mercury, arsenic, antimony, barium, copper,
Carlin, epithermal, and orogenic gold deposits, today mined almost exclusively for their gold content, have similar suites of anomalous trace elements that reflect similar lowsalinity ore fluids and thermal conditions of metal transport and deposition. Many of these trace elements are commonly referred to as critical or nearcritical elements or metals and have been locally recovered

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
On a Periodic Table, elements often found to associate with gold have been group/classified. Elements Universally Associated with Gold Elements Typical in Minerals Commonly Associated with Gold Elements Concentrated in Gold Bearing Mineral Associations of Individual Orebodies Elements Characteristic of Gold Only Ores Elements with Traces Commonly found in Gold and its
Gold is actually a relatively scarce element on the crust of the earth, but it occurs in trace quantities spread throughout many different kinds of rocks and in many different geological environments. Although Anomalous amounts of gold or elements known to be associated with gold in valuable deposits such as arsenic or Mercury,
These elements (Hg, Sb, and Tl) are closely associated with eath other in epithermal deposits, but do not covary with gold. Furthermore, Bi, Te and W are less enriched in epithermal deposits as

It is fairly common that new deposits can be found along this linear zone of deposition by looking for extensions along the line of deposition. Similar Geologic Areas Nearby: If a certain rock type or geologic environment has been productive for gold in one area, and the same rock type or environment occurs a few miles away in the same mountain range, it may well be worthwhile to investigate.

#0183;#32;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 ( McCandless et al., 1997, Outridge et al., 1998, Penny, 2001).
#0183;#32;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 #176;C (Gammons and WilliamsJones, 1997), and with decreasing temperature being the primary mechanism causing gold
