Melts, magmas, metals and magmatic sulfides: Source variability and multi-stage sulfide saturation

摘要：

Economically significant magmatic sulfide deposits form in a variety of tectonic settings throughout geological time. Many deposits are associated with preserved high-level Large Igneous Provinces (LIPS) or their exposed root zones. The difference in tectonic setting is often reflected in the chemistry of donor melts which is diverse with respect to initial melt composition in terms of major element variability and the level of trace-element enrichment.Geochemical data from a number of Active systems (A), Kambalda, Jinchuan, Norilsk - Talnakh, Voiseys Bay and Kabanga; Transitional systems (T), Platreef and Duluth Complex; will be contrasted with data from Passive systems (P), Bushveld Complex; in order to highlight the variability in initial melt composition and the impact this has on sulfide saturation, sulfide processing and sulfide composition.
