Sulfur Isotope Composition of Ru–Os Sulfides from the Verkh-Neivinsky Dunite-Harzburgite Massif (Middle Urals, Russia): New Data

Аннотация

This study presents the first data set of sulfur isotope compositions of primary Ru–Os sulfides, represented by laurite (RuS₂) – erlichmanite (OsS₂) series, within a primary platinum-group mineral (PGM) assemblage derived from the Verkh-Neivinsky dunite-harzburgite massif, a typical example of the mantle ophiolite association at the Middle Urals. The S-isotope signatures of Ru–Os sulfides studied are consistent with derivation of the ore material from a mantle source.
