Chalcophile Element

Chalcophile Element

 

any one of various chemical elements of sulfide ores according to the classification of the Norwegian geochemist V. M. Goldschmidt. Chalcophile elements constitute side groups in the periodic system of elements and include 19 elements: S, Cu, Zn, Ga, Ge, As, Se, Ag, Cd, Ln, Sn, Sb, Te, Au, Hg, Tl, Pb, Bi, and Po. Their metals have a specific affinity for S, Se, and Te.

Chalcophile elements make up 0.046 percent of the mass of the earth’s crust; however, because of their ability to accumulate under certain conditions, they form ore deposits, primarily hydro-thermal vein deposits. Sulfides of copper, lead, zinc, and silver in sedimentary rocks form stratiform (blanket) deposits.

Characterized by a high content of U, Mo, V and some chalcophile elements, the complex is a potential resource of a variety of metals (Hade & Soesoo 2014).
Some siderophile and chalcophile elements such as Au and the Platinum Group elements (PGE's) are more strongly partitioned into immiscible sulfide liquid than Ni.
