Goldschmidt classification
The Goldschmidt classification , named after Victor M. Goldschmidt , is a classification of chemical elements commonly used in geochemistry according to their affinity to different carrier phases in siderophil ( iron- loving, from σίδηρος (sideros, Greek) = iron), lithophil ( silicate - loving, from λίϑο? (lithos, Greek) = stone; rock), chalcophilic ( sulfur- loving, from χαλκός (chalkos, Greek) = ore, metal, especially copper) and atmophilic ( gas- loving, from atmosphere). The Goldschmidt classification plays a role in the differentiation of an initially chemically homogeneous planet or asteroid . H. in the formation of an iron core, as well as a mantle and a crust. For example, siderophilic elements are preferably found in the iron core and lithophilic elements are preferably found in the mantle or crust of a planet.
The Goldschmidt classification represents a successful application of the principles of the HSAB concept .
Classification
- Atmophile elements: H , N , noble gases
- Chalcophilic elements: Ag , As , Bi , Cd , Cu , Ga , Hg , In , Mo , Pb , Po , S , Sb , Se , Te , Tl , Zn
- Lithophilic elements: Al , At , B , Ba , Be , Br , Ca , Cl , Cr , Cs , F , I , Hf , K , Li , Mg , Mn , Na , Nb , O , Rb , Sc , Si , Sr , Ta , Th , Ti , U , V , Y , Zr , W , lanthanoids
- Siderophilic elements: Au , C , Co , Fe , Ge , Ir , Ni , Os , P , Pd , Pt , Re , Rh , Ru , Sn
- Highly siderophilic elements: Au , Ir , Os , Pd , Pt , Re , Rh , Ru
Only the main affinities are considered here. Some elements have an affinity for several phases, e.g. B. Oxygen (O) is lithophilic and atmophilic.
