Mantle-derived magmas and magmatic Ni-Cu-(PGE)

2021-7-26  Magmatic Fe-Ni-Cu ± platinum-group element (PGE) sulfide deposits form when mantle- derived mafic and ultramafic magmas become saturated in sulfide and segregate immiscible sulfide liquid, commonly following interaction with crustal rocks.

Mantle-derived magmas: intraplate, hot-spots and mid

2015-11-1  1. Introduction. In the plate tectonics paradigm for the modern Earth, it is generally accepted that the primary differentiation of Earth’s crust from the upper mantle is the result of intrusion and extrusion of basalts at mid-ocean ridges, augmented by other intraplate basaltic

The mineral system approach applied to magmatic Ni-Cu-PGE ...

Most magmatic Ni-Cu-PGE sulphide deposits occur within long-lived magma pathways fed by high degree partial melts of the mantle. Holistic mineral-system analysis for such deposits has some parallels with dominantly hydrothermal systems, but also some important differences. Major provinces are associated with large volumes of magma erupted at ...
