element composition of vein material from epithermalgold deposits. Commonly, only the vein mineralogy is reported for these deposits,and is used to inferthe corresponding geochemical response (it can be safely assumed that where tellurides,for example,are generallypresent in veins, Te is a geochemical componentof the vein).

Mineral deposit, aggregate of a mineral in an unusually high concentration.. About half of the known chemical elements possess some metallic properties. The term metal, however, is reserved for those chemical elements that possess two or more of the characteristic physical properties of metals (opacity, ductility, malleability, fusibility) and are also good conductors of heat and electricity.

The Olympic Dam deposit is unusual in that it contains large amounts of rare earth elements and uranium. An economic method for recovering rare earth elements from these deposits has not yet been found. Many other deposits of this type have been identified around the world, but information on their rare earth elements content is generally lacking. Trace amounts of rare earth elements have also ...

Hydrothermal mineral deposit, any concentration of metallic minerals formed by the precipitation of solids from hot mineralladen water (hydrothermal solution).The solutions are thought to arise in most cases from the action of deeply circulating water heated by magma. Other sources of heating that may be involved include energy released by radioactive decay or by faulting of the Earth''s crust.
