Difference Between Chalcophile and Siderophile Elements

Chacophile elements are chalcogen-loving elements, while siderophile elements are the iron-loving elements. The key difference between chalcophile and siderophile elements is that chalcophile elements occur near the surface of the earth, whereas siderophile elements occur near the core of the earth.

What are Chalcophile elements?

The term chalcophile (derived from the Greek for copper- loving) was originally introduced by Goldschmidt (1923) to describe the group of elements that are concentrated in sulfide minerals in meteorites. Traditionally this group is defined as the elements Ag, As, Bi, Cd, Cu, Hg, In, Pb, S, Sb, Se, Te, Tl, and Zn.

What are Siderophile elements Lithophile elements?

The siderophile elements include the highly siderophilic ruthenium, rhodium, palladium, rhenium, osmium, iridium, platinum, and gold, the moderately siderophilic cobalt and nickel, in addition to the "disputed" elements mentioned earlier – some sources even include tungsten and silver.

What is a Lithophile?

Lithophile is a term used to refer to elements that are prefer- entially partitioned into silicate minerals as opposed to sul- fides or metals. The Goldschmidt Classification of the Elements. Goldschmidt (1929; 1937) used various chemical consider- ations to classify elements as lithophile (coined from the.

What is geochemical affinity?

geochemical affinity Affinity of an element for a particular environment. A Dictionary of Earth Sciences. × "geochemical affinity ."

What two elements make up most of the earth's core?

Unlike the mineral-rich crust and mantle, the core is made almost entirely of metal—specifically, iron and nickel. The shorthand used for the core's iron-nickel alloys is simply the elements' chemical symbols—NiFe. Elements that dissolve in iron, called siderophiles, are also found in the core.

What are high field strength elements?

This term is restricted to elements whose ions have a small radius and high charge, therefore high associated electric field: high field strength. ... In geochemistry the term high field strength is mostly reserved for elements Hf, Zr, Ti, Nb and Ta as a group.
