Geological major elements are defined as those elements that compose 95% of the earth's crust. They are Si, Al, Ca, Mg, Na, K, Ti, Fe, Mn and P. Major element (whole rock) geochemistry has traditionally been done by X-ray fluorescence (XRF) but such analysis can now be performed by inductively coupled plasma (ICP) technologies.

Gold is one of the group 11 elements, the others being silver and copper. It is among the least reactive solid elements in the periodic table. This is why gold is found naturally in the environment in rocks, alluvial deposits and veins. Sometimes it is also found as a compound with the element .

Gold is usually alloyed in jewellery to give it more strength, and the term carat describes the amount of gold present (24 carats is pure gold). It is estimated that all the gold in the world, so far refined, could be placed in a single cube 60 ft. on a side. The most common gold compounds are auric chloride (AuCl 3) and chlorauric acid (HAuCl ...
