The first studies on sulfur isotope geochemistry were performed approximately sixty years
ago (eg, Thode et al. 1949; Trofimov 1949). Since these early measurements on terrestrial …

Abstract The Xiarihamu Ni–Cu deposit of Qinghai Province, China, is located in the central
region of the Eastern Kunlun Orogen (EKO), which is bordered by the Qaidam block (QDM) …

Conceptual models that describe the essential characteristics of groups of similar deposits
have a long and useful role in geology. The first models were undoubtedly empirical …

Nickel-copper sulfide deposits are found at the base of mafic and ultramafic bodies. All their
host rocks, except the Sudbury Igneous Complex, are thought to be mantle-derived melts …

Understanding the source of metamorphic sulfur is critical to clarifying the complete cycle of
ore genesis, from source to sink, for several mineral deposit types. In this study, a mass …

The importance of externally derived sulfur in the genesis of sulfide-rich, magmatic Ni-Cu-
(platinum group element [PGE]) deposits remains a key, yet unresolved, issue. Calculations …

Abstract Magmatic Ni-Cu sulfide deposits form as the result of segregation and
concentration of droplets of liquid sulfide from mafic or ultramafic magma, and the …

This book is written by a leading authority on the subject of magmatic sulfide deposits. An
overview of deposit types, accompanied by a summary of the resources of nickel, copper …

Empirical equations to predict the sulfur content of a mafic magma at the time of sulfide
saturation have been developed based on several sets of published experimental data. The …

Process models for ore formation in magmatic Ni–Cu–platinum group element (PGE) sulfide
systems require that S saturation is achieved in a mafic–ultramafic magma. Traditional …
