trace elements associated with gold deposits

Trace elements in fluid inclusions of sediment-hosted gold

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

Metals and Other Trace Elements USGS.gov

Many human activities also contribute trace elements to the environment—mining, urban runoff, industrial emissions, and nuclear reactions are just some of the many manmade sources. Trace elements tend to concentrate in sediment, but also can dissolve to some degree in water, and can present a risk to human and aquatic health.
