This sulfur contained abundant inclusions of pyrite (Fe[S.sub.2]), covellite (CuS), and Cu-As sulfosalts, as well as measurable amounts of Au, Ag, Ga, Ge, Tl, and other chalcophile elements.
Our data show that Ebeko sulfur is enriched in volatile chalcophile elements.
Mineralogists and geochemists explore highly siderophile elements, which strongly prefer metal, and chalcophile
elements, which strongly prefer sulfide, relative to silicate or oxide phases, at very high temperatures.

PC4 was made up of a mixture of lithophile (Be and Y) and chalcophile
(Cd and Zn), suggesting that the elements were associated with silicates and sulphides, respectively.
(1995) indicated presence of three levels of chocolate brown coloured clay layers, less than 1 cm thick and separated from each other by 25 - 30 cm, heavily enriched with Ir, Os and other siderophiles together with chalcophiles
(Se, Sb, Ag, As and Zn) and depleted in lithophiles (Sc, Hf and Al) within the intertrappean bed of Anjar, in the western periphery of the Deccan volcanic province (Fig.1).
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.
A total of 10 chalcophile
elements (Ag, As, Bi, Cd, Cu, Hg, Pb, Sb, Se, and Zn) were examined for evidence of glacial dispersal.
Creaser titled "A review of the Rhenium-Osmium (Re-Os) isotope system with application to organic-rich sedimentary rocks" emphasizes the importance of the Re-Os isotope system to the direct dating of sedimentary rocks, particularly black shales in which these broadly chalcophile
and siderophile elements are concentrated by reductive extraction from seawater.
His four classifications are still used today: the lithophiles (rock-lovers), the chalcophiles
(ore- or sulfur-lovers), the atmophiles (gas-lovers) and siderophiles, the iron-lovers.
The radial differentiation of the aforementioned chalcophiles
in the soils of different elementary geochemical landscapes is displayed so that it quite clearly reflects the material composition of genetic horizons of the respective soils, the concentration of total carbon in them and the effect of activities of geochemical barriers related with them.
