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.
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.
6], first natural niobium-rich sulfide from the Khibina alkaline complex, Russian Far North: evidence for chalcophile behavior of Nb in a fenite.
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.
