Trace elements and rare earth elements (REE) of the sulfide minerals were determined by inductively‐coupled plasma mass spectrometry. The results indicate that V, Cu, Sn, Ga, Cd, In, and Se are concentrated in sphalerite, Sb, As, Ge, and Tl are concentrated in galena, and almost all trace elements in pyrite are low.

ABSTRACT Trace element analysis of placer gold can be used as a valuable exploration tool in order to determine the original deposit source and
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.
associated granite suites may elsewhere be associated with Sn-W and W-Mo-Bi-(Sn) mineralisation. • Trace elements in alteration associated with fractionated granites can include F, B, Cs, Rb, and Li. Yttrium-, Th- and REE-bearing minerals such as xenotime can be present in associated greisens and veins. Surficial geochemical criteria
Pathfinder element patterns likely reflect the temperature-controlled substitution of trace elements into pyrite and the distribution of base metal sulphides and Bi-Pb-Ag sulphosalt minerals associated with gold (Figure 4; Figure 5). Bismuth shows the closest spatial and

Gold Pathfir Trace Element Gemhemishy JAMBOREE PROPERTY May 1991 Page I 1.0 INTRODUCITON In 1991 139 soil samples and 31 rock samples taken within the Jamboree 1-4, 18 mineral claims were submitted to Acme Labs, Vancouver, B.C., for analysis for gold pathfinder elements: As, Sb, Bi, Ge, Se, Te and Hg. Am of the program was to help locate target areas
Chemical elements such as Ag, As and Sb are trace elements that are enriched in almost all types of gold deposits and have higher average crustal abundances than gold. Consequently, identification of anomalous concentrations of these is a valuable tool in gold exploration. Other pathfinder elements associated with some gold deposits are B. Ba, Bi, C, Cd, Cu, Hg. Pb. Te, Ti and Zn.
Trace elements in minerals The investigated metals and semimetals could be present in porphyry copper type mineralization as own minerals (such as gold, molybdenite), but also as trace elements in the network of some sulfides and sulfosalts such as pyrite, chalcopyrite, bornite, tetrahedrite-tennantite etc.
Significant advances in our understanding of rare-element deposits have been made over the last fifteen years, and this, together with the increased demand for rare-elements, has created a need for a new summary of our understanding of rare-element geochemistry and mineral deposits. Most rare-element mineral deposits are associated with highly ...
